Non-equilibrium polymeric complex fluids
… larger than atomic. Their usage is typically in non-equilibrium conditions, however traditional methods for measuring rheology are not appropriate for measuring samples with gradients present, such as temperature and concentration. In this work a safe and easy to use optical tweezer (OT) …

Laser diagnostics of non-equilibrium plasmas
… loading into N2 , as a first step towards the non-thermal synthesis of NO for fertilizer production. The complicated system that a non-equilibrium plasma represents requires sophisticated diagnostics. Such diagnostics have to be species specific and provide spatial and time resolved information …

Relaxation phenomena during non-equilibrium growth
… constant. The global quantities depend in a non-trivial way on two different times. We discuss the dynamical scaling forms of global correlation and response functions. For global functions related to the surface width, we show that the scaling behavior of the response can depend on how the …

Non-equilibrium phase separation in active matter
… environment locally, forms an important class of non-equilibrium systems. Recently there has been a surge of interest in active systems with chemical reactions, fuelled in particular by studies in biomolecular condensates, or ‘membraneless organelles’, within cells. In contrast to their passive …

Fluctuation-induced phenomena in non-equilibrium systems
… in systems away, possibly even far, from equilibrium due to their motion either in or out of thermal equilibrium. This subject encompasses several topics in physics including the dynamical Casimir effect in the presence of moving boundaries, and non-contact friction between objects in …

Kinetic algorithms for non-equilibrium gas dynamics
… schemes have been developed for flows with nonequilibrium thermodynamics and chemistry. These schemes are derived from the Boltzmann equation with the resulting Euler schemes developed as moments of the discretized Boltzmann scheme with a locally Maxwellian velocity distribution. Application …

Non-Equilibrium Dynamics of Second Order Traffic Models
… is unstable, and small perturbations grow into nonlinear traveling waves, called jamitons. The case where the SCC is satisfied has been studied extensively. However, what is essentially unstudied is the question: which jamiton solutions are dynamically stable? To understand which stop-and-go …

Contributions to the Theory of Non-Equilibrium Thermodynamics
… a generalization of the current theory of non-equilibrium thermodynamics. The current theory was presented in 1953 by Onsager and Machlup, its mathematical context goes back to the 1930 paper of Uhlenbeck and Ornstein on Brownian motion, and the physical foundations for that approach go …

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 …

First principles calculations on ZnO non-equilibrium phase
… the electronic and optical properties for the non-equilibrium boron-nitride phase of ZnO have been studied. To understand the difference between the BN phase and the equilibrium WZ phase, first principles approaches such as DFT, hybrid functional and the GW approximation have been studied and …

Rare events and dynamics in non-equilibrium systems
… study classical Cosserat systems, and numerous non-classical variations. As a paradigmatic example we first study the Cosserat rod model, we identify its configuration space as a curve in $SE(3)$, the Lie group of translations and rotations on Euclidean space, and use the Lie algebra-Lie group …

Focused Ion Beam Fabricated Non-equilibrium Superconducting Devices
The developments over the last decade in Focused Ion Beam (FIB) instrument technology have reached a point where there is sufficient control of an ion beam to make cuts, trenches, and other shapes in a sample on a scale of tens of nanometers. This work concentrates on the use of an FIB instrument …

Lithium-ion battery modeling using non-equilibrium thermodynamics
… focus of this thesis work is the application of non-equilibrium thermodynamics in lithium-ion battery modeling. As the demand for higher power and longer lasting batteries increases, the search for materials suitable for this task continues. Traditional battery modeling uses dilute solution …
