Non-equilibrium physics: from spin glasses to machine and neural learning
… in disordered systems through statistical physics. We chart a roadmap for our efforts in this thesis based on two axes: learning mechanisms (long-term memory vs. working memory) and learning dynamics (artificial vs. natural). We begin our exploration from the long-term memory and artificial …

Collective structure and dynamics of colloids far-from equilibrium
… this simplified model system, many aspects of physics of life, such as pattern formation, swarming/flocking behavior and response to heterogeneous environment, can be explored. More importantly, by stepping bravely from the conventional equilibrium framework of thinking, active matter opens a …

Strongly interacting Fermi gases : non-equilibrium dynamics and dimensional crossover
… gases address fundamental problems in many-body physics. This thesis describes experiments on strongly-interacting gases of fermionic atoms, with a focus on non-equilibrium physics and dimensionality. One of the fundamental dissipative processes in two-component gases is the transport of spin due …

Symmetry and its Signatures in Quantum Many-Body Dynamics
… properties of “typical” states and dynamics in equilibrium, even when keeping track of the precise dynamics of a particular many-body system is impossible. This challenge of tracking allowable states and dynamical transitions is only exacerbated for non-equilibrium systems, where one cannot rely …

Pattern-forming in non-equilibrium quantum systems and geometrical models of matter
… condensates can be modelled by means of a non-linear PDE which is strictly related to the Gross-Pitaevskii and the complex Ginzburg-Landau equations. Numerical simulations of this equation are used to investigate the robustness of the rotating vortex lattice which is predicted to …

Equilibration of deep neural networks and carrier chirality in Rashba systems
… whereas the second part with the decay of non-equilibrium states in strongly Rashba-coupled systems at low temperature. Deep learning is a conceptually simple, highly effective, and widely used tool, yet there remains insufficient understanding for why it works. The optimisation of deep …

Tuneable homogeneous Bose fluids close to and far from equilibrium
… phenomena in different regimes from adiabatic equilibrium to ‘true’ far-from-equilibrium. We first outline a cooling effect driven by three-body recombination, which has traditionally been associated with heating and adverse effects. Three-body loss in a partially condensed three-dimensional …

Strongly correlated quantum fluids and effective thermalization in non-Markovian driven-dissipative photonic systems
… essential features. This interference phenomenon called ``quantum degeneracy'' which occurs at weak temperatures, leads to spectacular collective behaviours such as the celebrated Bose-Einstein Condensation (BEC) phase transition, where a macroscopic fraction of a bosonic system of particles …
