Nonequilibrium Phenomena in Multiphase Flow, Transport, and Phase Change in Porous Media: Pore-Level Physics, Network Modeling, and Upscaling
… assumption is oftentimes violated due to the nonequilibrium physical processes in the complex pore spaces within each REV. This dissertation aims to test the equilibrium assumption and study the impact of pore-scale nonequilibrium physics on the REV-scale behaviors in subsurface environment …

Nanocircuits with superconductivity: Nonequilibrium studies
… nanoelectronics and, in particular, nonequilibrium phenomena which come about when the concept of temperature loses its significance in nanoscale electric circuits. Under more conventional circumstances, these nonequilibrium phenomena are smothered by thermal motion or die away at …

Theory of nonequilibrium transport based on a class of chaotic fluctuations
… particle under the action of a class of nonequilibrium chaotic fluctuations. By considering a perturbative Perron-Frobenius approach on a strongly damped particle in a potential field, we arrive at a transport equation in the form of an inhomogeneous Smoluchowski equation with a source …

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 …

Discrete time crystals beyond the MBL paradigm
… time, avoid ergodicity, and realize a novel nonequilibrium phase of matter. In most previous proposals of DTCs, this peculiar behavior relied on the presence of (strong) disorder. Indeed, according to the celebrated mechanism of many-body localization (MBL), disorder can avert the otherwise …

Flashing flow of refrigerant HFC-134a through a diabatic capillary tube
… liquid to a vapor-liquid mixture. Metastable phenomena in the flow, i.e. a thermal nonequilibrium phenomena, may exist within a flashing process. Whereas a literature survey showed that the metastable flow of refrigerant was only observed in adiabatic capillary tubes, the experiment …

Control of stochastically interacting systems on networks
… processes, smart manufacturing, and transport phenomena. In the first part of the thesis, control of spreading processes on lattices is considered. Analysis and control of spreading processes is difficult because the dimensionality of state space is often large. A common approach to this issue …

Coffee-Rings and Glasses: Colloids Out of Equilibrium
… experiments that utilize colloids to explore nonequilibrium phenomena. Specifically, the deposition of particles during evaporation and the glass transition are explored. In the first set of experiments, we found that particle shape has a profound effect on particle deposition. We evaporated …
