Renormalized kinetic theory of classical fluids in and out of equilibrium [PDF]

, 2011
We present a theory for the construction of renormalized kinetic equations to describe the dynamics of classical systems of particles in or out of equilibrium.

Atomic Size Misfit for Electrocatalytic Small Molecule Activation

Advanced Functional Materials, EarlyView.
This review explores the application and mechanisms of atomic size misfit in catalysis for small molecule activation, focusing on how structural defects and electronic properties can effectively lower the energy barriers of chemical bonds in molecules like H2O, CO2, and N2.

Appearances are deceptive: can graviton have a mass?

Journal of High Energy Physics
We study the dynamics of linear gravitational perturbations on cosmological backgrounds of massive fermionic fields. We observe that, when gravitational and matter action are expanded to quadratic order in gravitational perturbations on cosmological ...

Wigner Function and Entanglement Entropy for Bosons from Non-Equilibrium Field Theory

, 2018
We propose a new method of calculating entanglement entropy of a many-body interacting Bosonic system (open or closed) in a field theoretic approach without replica methods.

Population trapping and inversion in ultracold Fermi gases by excitation of the optical lattice - Non-equilibrium Floquet-Keldysh description

, 2013
A gas of ultracold interacting quantum degenerate Fermions is considered in a three dimensional optical lattice which is externally modulated in the fre- quency and the amplitude.

Resummation of perturbation series in non-equilibrium scalar field theory [PDF]

Physics Letters B, 1995
The general behaviour of perturbation series in non-equilibrium scalar field theory is analysed in some detail, with a particular emphasis on the ``pathological terms'', generated by multiple products of $ $-functions. Using an intuitive regularization method, it is shown that these terms give large contributions at all orders, even when considering ...

Rational Fine‐Tuning of MOF Pore Metrics: Enhanced SO2 Capture and Sensing with Optimal Multi‐Site Interactions

Advanced Functional Materials, EarlyView.
A pore tuning strategy to amplify the multi‐site MOF‐SO2 interactions is proposed to achieve an enhanced trace SO2 capture and chemiresistive sensing in highly stable isostructural DMOFs by annelating benzene rings. This work provides a facile strategy to achieve tailor‐made stable MOF materials for specific multifunctional applications.

Loop corrections in Minkowski spacetime away from equilibrium. Part I. Late-time resummations

Journal of High Energy Physics, 2023
Loop corrections to unequal-time correlation functions in Minkowski spacetime exhibit secular growth due to a breakdown of time-dependent perturbation theory.
