Mechanistic investigation of coordinated conformational changes in multisubunit ion channels and enzymes
… where ATP hydrolysis takes place, unexpected non-equilibrium gating is observed on longer time scales. These results imply that channel gating is coupled to non-equilibrium processes other than ATP hydrolysis by SUR1. The second system studied for coordinated conformational change was ClpAP.

Physical interpretation of coarse-grained bead-spring models of complex fluids
… accounting for both thermal fluctuations and non-equilibrium processes. This has proven to be challenging with traditional approaches of energy minimization and perturbation in field theories. At the same time, simulations of highly coarse-grained particle-based models, such as lattice chain …

Non-equilibrium self-assembly processes of complex dipolar colloids
… influence of induced dipolar interactions on the non-equilibrium structure formation in quasi-two dimensional colloidal systems. On the one hand, theoretical models for certain experimentally realized systems are developed and investigated by means of Brownian Dynamics Simulations. To estimate …

Spin Systems far from Equilibrium: Aging and Dynamic Phase Transition
Among the many non-equilibrium processes encountered in nature we deal with two different but related aspects. One is the non-equilibrium relaxation process that is at the origin of \'aging phenomena••, and the other one is a non-equilibrium phase transition, called ••dynamic phase transition••. …

Studies of hydrophobic organic pollutant interactions with cyclodextrin: implication for groundwater remediation
… Hoff equation for all HOPs tested. A three-phase equilibrium model was used to interpret air-water-CD partitioning data. Our results show that HOP CD-water partition coefficients decrease linearly with increasing temperature. Adsorption isotherms of TCE to the granular activated carbon (GAC), …

Understanding surface reactivity, local structure, and lithium-metal dendrite initiation in garnet solid electrolytes
… using an Onsager formalism to model the various non-equilibrium processes involved in lithium metal plating at the lithium metal electrode - electrolyte interface and possible solutions to increase ICCD in solid electrolytes are proposed.

Non-Markovian Dynamics of Open Quantum Systems
… been coarse grained away. This model describes non-equilibrium processes more general than scattering-matrix formulations. Furthermore, the microscopically-derived environment provides a model of noise, dissipation and decoherence far more general than Markovian (white noise) models. The latter …

Non-equilibrium dynamics in three-dimensional magnetic spin models and molecular motor-inspired one-dimensional exclusion processes
… the relaxation dynamics of two distinct non-equilibrium processes: relaxation of three-dimensional antiferromagnetic lattice spin models with Heisenberg interaction following a critical quench, and a one-dimensional exclusion process inspired by the gear-like motion of molecular motors. …

Single-molecule microscopy reveals details of heterochromatin reorganisation at the onset of mouse ES cell differentiation
… were found, as well as evidence for non-equilibrium processes. Transient slowdown in HP1β diffusion upon differentiation was observed, potentially reflecting a change in the nuclear environment. However, analysis of small-scale chromatin movement showed no change in dynamics between …

Operando Optical Tracking of Ion Dynamics and Degradation in Battery Electrodes
… our ability to follow and understand the dynamic processes occurring in functioning materials under realistic conditions, in real time, and on the nano- to meso-scale. Currently, *operando* imaging of lithium-ion dynamics requires sophisticated synchrotron X-ray or electron microscopy techniques, …

Aspects of Quantum Fluctuations under Time-dependent External Influences
The vacuum of quantum field theory is not empty space but filled with quantum vacuum fluctuations, which give rise to many intriguing effects. The first part of this Thesis addresses cosmic inflation, where the quantum fluctuations of the inflaton field freeze and get amplified in the expanding …

Non-Equilibrium Disordering Processes In binary Systems Due to an Active Agent
In this thesis, we study the kinetic disordering of systems interacting with an agent or a walker. Our studies divide naturally into two classes: for the first, the dynamics of the walker conserves the total magnetization of the system, for the second, it does not. These distinct dynamics are …

Processing and irradiation-driven evolution of refractory microstructures
… two lenses: one driven by processing under non-equilibrium conditions, and the other driven by non-equilibrium or extreme environments experienced during service-like conditions (specifically, under irradiation). The broad goal is to understand how underlying mechanisms can drive …
