A method for detecting nonequilibrium dynamics in active matter
… It is important to determine the extent of such nonequilibrium activity during cellular processes to understand cell function. Here we present a framework for measuring nonequilibrium activity in biological active matter using time reversal asymmetry based on the Kullbeck-Leibler Divergence …

Modeling and simulation of the equilibrium and nonequilibrium dynamics of DNA
… have been made to understand the underlying dynamics of the formation and dissipation of these structures by means of novel experiments. In these experiments, single molecules of DNA are subjected to forces and torques similar to the ones they would experience within the cell in order to …

Low frequency charge-density wave dynamics
The low frequency dynamics of the charge-density waves in NbSe$\sb3$ and TaS$\sb3$ were investigated using low frequency conductance fluctuations. Simultaneous measurements of the fluctuations in the voltage and the differential resistance revealed a theory of threshold voltage fluctuations can …

Pattern Formation in Active Nematics
… presents analytical and numerical studies of the nonequilibrium dynamics of active nematic liquid crystals. Active nematics are a new class of liquid crystals consisting of elongated rod-like units that convert energy into motion and spontaneously organize in large-scale structures with …

Dynamics from an equilibrium lattice model of a microemulsion
… behavior has been extended to investigate the nonequilibrium dynamics of such system. The model is based on "Dynamical Monte Carlo" simulations which apply a coarse-grained velocity field onto a conventional Monte Carlo lattice, so as to represent realistically interactions between particles, …

Dynamical pairing states in cold gases
… Ginzburg-Landau theory are not applicable. 'The nonequilibrium dynamics can be explored in cold Fermi gas at a Feshbach resonance, a system with magnetically tunable interaction. Motivated by recent experiments, in Chapters 2 and 3 we study the pairing of fermions when a sudden switch of …

Non-equilibrium dynamics of adsorbed polymers and filaments
… work, we discuss two subjects related to the nonequilibrium dynamics of polymers or biological filaments adsorbed to two-dimensional substrates. The first part is dedicated to thermally activated dynamics of polymers on structured substrates in the presence or absence of a driving force. The …

Nonlinear resonance and excitability in interconnected systems
… behaviour. While in the context of equilibrium dynamics there is a well-developed theory that can account for robustness and optimality in this process, we still lack a corresponding methodology for nonequilibrium dynamics and in particular oscillatory behaviours. With the aim of fostering such …

Time resolved dynamics of charge density waves in solids : an uncorrelated and a correlated case
… scattering. However, little is known about their nonequilibrium properties following photoexcitation. In this thesis, we use time resolved optical measurements to characterize the nonequilibrium dynamics of charge density wave systems. In the time resolved optical experiments in this work, an …

Nonzero temperatures and emergent disorder in spin liquids
… of the plateaux. Finally, I consider the nonequilibrium dynamics of quantum spin liquids in closed systems at finite energy density. In this context, the emergent (self-generated) nature of the disorder plays a crucial role, allowing the system to generically exist in a superposition of …

Understanding neural mechanisms of strategic learning: correlates, causality, and applications
… which equilibria might arise as a consequence of nonequilibrium dynamics among agents with bounded rationality. Empirically, learning models have been widely used to describe the evolvement of observed behavior over the course of field and laboratory experiments. While game theorists are trying to …

Atomistic Insights into Alloy Solidification using Machine-Learning Potentials
… reveal that alloy processing can lead to nonequilibrium steady states of SRO that differ qualitatively from any equilibrium configuration. We attribute this behavior to an inherent ordering bias introduced by nonequilibrium dynamics during solidification. These findings suggest that …
