Nonlinear dissipative dynamics of optomechanical and laser arrays
In this thesis, we study nonlinear dissipative dynamics of two different systems: (i) synthetic dynamical gauge fields for photons in optomechanical arrays and (ii) laser arrays with a topologically nontrivial structure. The chosen models are relevant to state-of-the-art optomechanical experiments …

Counterion Behavior in Biopolymers
… to observe inter-ion correlations. From the dissipative dynamics of an unexpected acoustic phonon-mode associated with the counterions, we show that the counterions behave as a dense hard-sphere fluid and obtain an inter-ion distance which can be controlled by changing ion number density …

Dynamics of impurities and trapped Bose-Einstein Condensates
… new frontiers in the context of non-equilibrium dynamics. These possibilities can be used for a wide variety of applications, ranging from quantum simulations to quantum metrology. In this thesis, we investigate designing the confinement of tightly trapped impurities in a BEC reservoir to study …

Exploring Interacting Bose Gases in and out of Equilibrium
… lead to a complex interplay between coherent and dissipative dynamics. By disentangling these two processes, we have caught a glimpse of the promises that the unitary Bose gas holds. In particular, we observe the emergence of universal behavior, and find that the gas features a well defined …

Perturbative and non perturbative effects in the Standard Model and orbifolded ADS/CFT based theories
… the Higgs vacuum expectation value given by the dynamics of the StandardModel and study the non-adiabatic production of both bosons and fermions, which is intrinsically non-perturbative. In theHartree approximation, we analyze the general expressions that describe the dissipative dynamics due to …

The role of topological defects and textures in the kinetics of phase ordering
… on the phase-ordering proceSs and point defect dynamics following a quench into both the uniaxial and biaxial nematiC phases of a quasi-2-dimensionalliquid crystalline system. The time dependences of the correlation function, structure factor, energy density, and number densities of topological …

Computational approaches to stochastic systems in physics and biology
… fluids, which incorporates a conservative and dissipative part, and I also allow the fluid to be externally forced by a normal fluid. I use then this model to calculate scaling laws arising from the stochastic interactions of the topological defects exhibited by the modeled fluid while …

Dissipative Matsubara Dynamics
The two most widely used path-integral chemical dynamics methods are Ring-polymer molecular dynamics (RPMD) and Centroid molecular dynamics (CMD). Both of these were originally proposed as heuristic approximations, which were justified by analytic limits and empirical evidence.In 2015, the …
