**ACTIVE PROJECTS**

GUnDHam- Generating unstable dynamics in dispersive Hamiltonian fluids | ||

Consolidator Grant 2023-2028 | PI: ALBERTO MASPEROMathematics | |

Energy cascades associated with turbulence and extreme phenomena, such as the formation of anomalous waves are commonly observed in oceans, planetary atmospheres, and replicated in experimental laboratories. However, their mathematical description is still in its early stages. The GUnDHam project aims to help fill this knowledge gap by providing a solid theoretical foundation for their mathematical understanding. The research project will rigorously demonstrate the emergence of instability phenomena in certain dispersive Hamiltonian equations that govern the dynamics of fluids on large spatial scales, including water waves and geophysical fluids. |

FLEXIN- Context-dependent flexibility in innate behaviours and their underlying neural circuitry | ||

Starting Grant 2023-2028 | PI: KATJA REINHARDNeurobiology | |

Avoiding danger is one of the most essential and conserved set of behaviors, observed in most species from crabs to primates. To optimize an animal’s survival, the type, magnitude, and kinetics of avoidance responses need to be flexible and adaptable to the current context. However, the neural circuit elements that allow for this flexibility in behavioural output are largely unknown. Our aim is to identify how information about the environment and state can adapt behavioural decision making. |

CeleBH - The celestial road to a holographic description of black holes | ||

Starting Grant 2023-2028 | PI: LAURA DONNAYTheoretical Particle Physics | |

Black holes are at the root of the most striking puzzles that arise when attempting to combine Einstein's theory of gravitation with quantum mechanics; they are therefore thought to be key to a formulation of a theory of quantum gravity. In recent years, the so-called holographic correspondence has provided theoretical physicists with a very powerful approach to quantum gravity, but it has not been developed so far for realistic kinds of spacetimes, such as the universe we live in. By exploiting the powerful constraints implied by newly discovered symmetries that arise at spacetime boundaries, CeleBH aims at unveiling a holographic description of gravity for realistic spacetimes (celestial holography) and quantum properties of black holes. |

GeoSub - Geometric analysis of sub-Riemannian spaces through interpolation inequalities | ||

Starting Grant 2022-2026 | PI: LUCA RIZZIResearch Field: Mathematical Analysis, Modelling, and Applications | |

Sub-Riemannian spaces are geometrical structures that model constrained systems, and constitute a vast generalization of Riemannian geometry. In the last 10 years, a surge of interest in the study of geometric and functional inequalities on sub-Riemannian spaces revealed unexpected behaviors and intriguing phenomena that failed to fit into the classical schemes inspired by Riemannian geometry. GeoSub aims to develop a unified framework of geometric and functional interpolation inequalities adapted to sub-Riemannian manifolds and to use this theory to tackle old and new problems concerning the geometric analysis of these structures.

NP-QFT - Non-perturbative dynamics of quantum fields: from new deconfined phases of matter to quantum black holes | ||

Consolidator Grant 2020-2025 | PI: FRANCESCO BENINIResearch Field: Theoretical Particle Physics | |

When the degrees of freedom that constitute a quantum physical system are strongly coupled among each other, their collective low-energy behaviour can exhibit exotic, surprising and unconventional phenomena. At the same time, though, our most sophisticated tool to describe the quantum world ̶ quantum field theory ̶ becomes extremely difficult to use. A variety of examples is provided by deconfined quantum states of matter. Another context is gravity: by the AdS/CFT correspondence, a fully-consistent quantum gravity in Anti-de-Sitter space can be described in terms of an ordinary ̶ but strongly coupled ̶ quantum field theory in one dimension less. This project will develop innovative techniques to tame strong coupling, will exploit them to discover new deconfined phases of matter, and will unravel mysteries of quantum gravity and the quantum physics of black holes. |

MaMBoQ - Macroscopic Behavior of Many-Body Quantum Systems | ||

Starting Grant 2019-2024 | PI: MARCELLO PORTAResearch Field: Mathematical Physics | |

The project aims at developing mathematical methods for the rigorous description of the collective behavior of many-body quantum systems. The central theme is the notion of emergent effective theories: simplified models capturing the macroscopic features of complex systems. A main goal is to put on rigorous grounds the validity of effective theories of relevance in condensed matter physics, combining methods from functional analysis and statistical physics. The project focuses on applications to transport for graphene-like models, topological insulators and Weyl semimetals, and on the low-energy and non-equilibrium properties of large quantum systems in different scaling regimes. |

GRAMS - GRavity from Astrophysical to Microscopic Scales | ||

Consolidator Grant 2019-2024 | PI: ENRICO BARAUSSEResearch Field: Astroparticle Physics | |

General Relativity describes gravity on a huge range of scales, field strengths and velocities. However, despite its successes, it has been showing its age. Cosmological data support the existence of a Dark Sector, but may also be interpreted as a breakdown of our understanding of gravity. Indeed, gravitational theories can be built to reproduce the large-scale behaviour of the Universe (i.e. the existence of Dark Energy and/or Dark Matter) without any actual Dark Sector, while at the same time passing local tests of gravity thanks to non-perturbative screening mechanisms. GRAMS will explore the possibility that this non-perturbative screening may fail in the strong-field, highly dynamical systems that emit gravitational waves for LIGO and Virgo. This will allow for using gravitational wave observation to confirm or rule out a modified gravity origin for the Dark Sector. |

NEMO - New states of Entangled Matter Out of equilibrium | ||

Consolidator Grant 2018-2024 | PI: PASQUALE CALABRESEResearch Field: Statistical Physics | |

When a quantum system is suddenly brought out of thermodynamic equilibrium all excitations collectively participate in the ensuing dynamics, causing a plethora of unconventional and exotic effects. The theoretical study of the non-equilibrium dynamics is hampered by the fact that the time dependent many-body wave function is highly entangled on spatial scales which rapidly grow in time. Consequently, a satisfactory description of this dynamics is a challenge whose solution cannot prescind from a characterisation of the entanglement. The ambitious goal of this project is to find and characterise new non-equilibrium states of matter guided by their entanglement content. |

AGEnTh - Atomic Gauge and Entanglement Theories | ||

Starting Grant 2018-2023 | PI: MARCELLO DALMONTEResearch Field: Statistical Physics,Theory and Numerical Simulation of Condensed Matter | |

The overall aim of this project is to establish novel routes for the investigation of highly entangled quantum matter in atomic many-body systems, by addressing three complementary challenges along the way – probing, new phenomena, and implementations. The main goals are: i) devising scalable protocols for measuring entanglement in atomic quantum systems; ii) proposing gauge-theory-based mechanisms for the realization long-sought, highly-entangled states of matter, including topological phases supporting parafermion edge modes, and quantum spin liquids; iii) developing new tools for the implementation and understanding of atomic gauge theories. |

FIRSTORM - Modeling First-Order Mott Transitions | ||

Advanced Grant 2016-2023 | PI: MICHELE FABRIZIOResearch Field: Theory and Numerical Simulation of Condensed Matter | |

Mott insulators are “unsuccessful metals”, where conduction is impeded by strong Coulomb repulsion. Over the very last years experiments on narrow-gap Mott insulators have disclosed an unprecedented scenario where light pulses or applied bias voltage stabilize metal phases that were only metastable at equilibrium, which foreshadows exciting potential applications. These new data call for a theoretical understanding so far missing, which is indeed the scope of FIRSTORM ERC project. |

ARGOS will provide novel computational technologies to foster the important potential of scientific computing in industry, medicine, environmental sciences. The topic is strongly connected and integrated with Industry 4.0 as well as with digital twins developments. |

Stripe-o-Morph - Morphing tubular structures for adaptive biomedical devices | ||

Proof of concept grant 2022-2024 linked to MicroMotility Advanced Grant | PI: ANTONIO DE SIMONEResearch Field: Mathematical Analysis, Modelling, and Applications | |

Morphing tubular structures are extensively used in interventional medical devices (e.g., stents). Current solutions lack adaptability to complex geometries and to patient-specific needs. Stripe-o-Morph proposes the use of devices with superior morphing capabilities, bio-inspired by motile micro-organisms, previously investigated in the ERC AdG “MicroMotility”, and based on the concept of morphing-by-sliding of parallel strips. |

Advanced Grant 2012-2017 | PI: MATHEW E. DIAMONDResearch Field: Cognitive Neuroscience | |

CONCEPT examined how the brain transforms the neuronal representation of physical parameters into the neuronal representation of meaningful objects. An ideal platform for the inquiry is the rat whisker sensory system: it produces fast and accurate judgments of complex stimuli, yet can be broken down into accessible neuronal mechanisms. By combining behavioral tasks with measurements on neuronal activity throughout the cerebral cortex, CONCEPT has helped us understand the general principles for the cortical construction of perception. | ||

EDEQS - Entangling and Disentangling Extended Quantum Systems | ||

Starting Grant 2011-2016 | PI: PASQUALE CALABRESEResearch Field: Statistical Physics | |

The main aim of this project was to utilize entanglement measures to fully classify states of matter in low-dimensional systems. In addition, entanglement measures were used to benchmark the performance of numerical algorithms based on tensor network states. A second main aim of this project was to use the entanglement to identify the most important features of the non-equilibrium time evolution after a “quantum quench,” with a view to solve exactly the quench dynamics in strongly interacting integrable models. A particular question we addressed is which observables “thermalize,” which is an issue of tremendous current experimental and theoretical interest. |

SUPERBAD - Understanding high-temperature superconductivity from the foundations | ||

Starting Grant 2009-2015 | PI: MASSIMO CAPONEResearch Field: Theory and Numerical Simulation of Condensed Matter | |

The SUPERBAD project has contributed to developing a unified picture of high-temperature superconductivity in different classes of materials, including cuprates, iron-based materials, and fullerides. In all these materials, superconductivity appears as a "cure" for the bad metallic behavior arising as a consequence of strong electron-electron repulsion, which is responsible for the anomalies of the parent compounds and of the metallic state. We have successfully unified the phase diagram of these materials and explained a number of experimental results within a single theoretical scheme. |

FroM-PDE - Frobenius Manifolds and Partial Differential Equations | ||

The basic idea of the project was to apply the methods and results of the theory of integrable systems to non-integrable partial differential equations (PDEs). We do not promise to solve any PDE; however, in many cases, the solutions to a conservative non-integrable PDE in certain strongly nonlinear regimes exhibit integrable behavior. |
