Some problems on nonequilibrium systems
In this thesis, we study the evolution of two nonequilibrium systems: one is of practical significance for present technologies, and the other is of conceptual importance for future theoretical research.

Statistical dynamics of some nonequilibrium systems
… some statistical mechanical models that have nonequilibrium features either because of: external time-dependent fields; forces not satisfying detailed balance; nonpotential forces.

Some problems on spatial patterns in nonequilibrium systems
… study the evolution of spatial patterns in two nonequilibrium systems. In Chapter 1, we study the steady state of a 1-d cellular automata (CA) model of chemical turbulence. Empirically there are two interesting types of space-time patterns (depending on model parameters): aS phase which seems to …

Monte Carlo and Series Expansion Studies of the Anisotropic Driven Ising Lattice Gas Phase Diagram
While the statistical mechanics of systems in thermal equilibrium is a well established discipline, nonequilibrium systems are fundamentally much less well understood, even though most natural phenomena fall into the latter category. In particular, there is as yet no nonequilibrium analog for the …

Sensitivity and Memory in Physics and Biology
… abilities arise raises very basic problems in nonequilibrium physics. In Part I, I focus on dissipation and its role as a constraint on nonequilibrium behavior. In Part II, I present a set of simple, universal identities and inequalities constraining the sensitivity properties of nonequilibrium …

ADIABATIC PUMPING IN THE FLOQUET TOPOLOGICAL SYSTEMS
… recent two decades, as some observables in such systems are robust against local disorders due to the topological protection. The extension of the topological insulators to the nonequilibrium systems opens a new playground for physicists. Rich topological phases which have no static counterparts …

Statistical mechanics of strongly driven Ising systems
… based on the master equation to handle such nonequilibrium systems is introduced and applied to a mean field approximation, and one- and two-dimensional variants of the model. A novel type of phase transition related to spontaneous symmetry breaking and dynamic freezing occurs which depends …

Physics motivated algorithms for partial differential equations
Many nonequilibrium phenomena are spatially extended, and the most popular means to model them is the partial differential equation (PDE). Resultant PDEs are, however, often nonlinear, defying analytical approaches. Thus, devising efficient numerical algorithms to solve PDEs is important for the …

The edge of thermodynamics : driven steady states in physics and biology
… statistical mechanics dealt primarily with systems in thermal equilibrium, where detailed balance forbids the directed motion characteristic of living things. Formal variational principles have recently been discovered for nonequilibrium systems that characterize their steady-state …

Fluctuation theorems and work relations for single polymer rheology
… the molecular properties of polymeric systems ultimately determine their bulk macroscopic response and behavior in equilibrium and highly nonequilibrium conditions. As a result, the field of single polymer rheology can play a key role in establishing a molecular level understanding of …

Stochastic processes in T-cell signaling
… transitions can drive cellular systems out of stable states and lead to spurious responses. We proposed a theoretical and computational framework to identify key reactions or species that are responsible for regulating such stochastic transitions. The identification of these …

Floquet theory of electronic stopping processes of projectiles in solids
… based on Floquet theory for time-periodic systems. Floquet theory allows to find the solutions of time-periodic Hamiltonians through the same techniques used in time-independent problems: this provides the new framework with an intrinsic advantage over the the real time first principles …
