Novel Relaxation Time Approximation to the Relativistic Boltzmann Equation. [PDF]
Physical Review Letters, 2021 We show that the widely used relaxation time approximation to the relativistic Boltzmann equation contains basic flaws, being incompatible with micro- and macroscopic conservation laws if the relaxation time depends on energy or general matching ...

Transmon qubit with relaxation time exceeding 0.5 milliseconds [PDF]
, 2021 By using the dry etching process of tantalum (Ta) film, we had obtained transmon qubit with the best lifetime (T1) 503 us, suggesting that the dry etching process can be adopted in the following multi-qubit fabrication with Ta film.

How to "measure" a structural relaxation time that is too long to be measured? [PDF]
Journal of Chemical Physics, 2020 It has recently become possible to prepare ultrastable glassy materials characterized by structural relaxation times, which vastly exceed the duration of any feasible experiment.

Thouless and relaxation time scales in many-body quantum systems [PDF]
Physical review B, 2018 A major open question in studies of nonequilibrium quantum dynamics is the identification of the time scales involved in the relaxation process of isolated quantum systems that have many interacting particles.

Theoretical Model for the Structural Relaxation Time in Coamorphous Drugs. [PDF]
Molecular Pharmaceutics, 2019 We propose a simple approach to investigate the structural relaxation time and glass transition of amorphous drugs. Amorphous materials are modeled as a set of equal sized hard spheres.

The non-equilibrium attractor for kinetic theory in relaxation time approximation [PDF]
Journal of High Energy Physics, 2018 I demonstrate that the concept of a non-equilibrium attractor can be extended beyond the lowest-order moments typically considered in hydrodynamic treatments.

Slow relaxation in the two dimensional electron plasma under the strong magnetic field [PDF]
, 2006 We study slow relaxation processes in the point vortex model for the two-dimensional pure electron plasma under the strong magnetic field. By numerical simulations, it is shown that, from an initial state, the system undergoes the fast relaxation to a ...
