Molecular dynamics study on characteristics of reflection and condensation molecules at vapor-liquid equilibrium state.

open access: yesPLoS ONE, 2021
The kinetic boundary condition (KBC) represents the evaporation or condensation of molecules at the vapor-liquid interface for molecular gas dynamics (MGD).

The Effect of Different Pressure Conditions on Shock Waves in a Supersonic Steam Ejector

open access: yesEnergies, 2022
The complex flow phenomena in a three-dimensional supersonic steam ejector were simulated with a non-equilibrium condensation model including real physical properties in different pressure conditions.

Impact of phase state and non-ideal mixing on equilibration timescales of secondary organic aerosol partitioning [PDF]

open access: yesAtmospheric Chemistry and Physics, 2023
Evidence has accumulated that secondary organic aerosols (SOAs) exhibit complex morphologies with multiple phases that can adopt amorphous semisolid or glassy phase states.

Zero range condensation at criticality [PDF]

open access: yes, 2011
Zero-range processes with decreasing jump rates exhibit a condensation transition, where a positive fraction of all particles condenses on a single lattice site when the total density exceeds a critical value.

Non-equilibrium atomic condensates and mixtures: collective modes, condensate growth and thermalisation

open access: yesJournal of Physics B: Atomic, Molecular and Optical Physics, 2016
The non-equilibrium dynamics of trapped ultracold atomic gases, or mixtures thereof, is an extremely rich subject. Despite 20 years of studies, and remarkable progress mainly on the experimental front, numerous open question remain, related to the growth, relaxation and thermalisation of such systems, and there is still no universally-accepted theory ...

Strongly non-equilibrium Bose–Einstein condensation in a trapped gas [PDF]

open access: yesPhysics Letters A, 2001
We present a qualitative (and quantitative, at the level of estimates) analysis of the ordering kinetics in a strongly non-equilibrium state of a weakly interacting Bose gas, trapped with an external potential. At certain conditions, the ordering process is predicted to be even more rich than in the homogeneous case.

Polariton lasing and energy-degenerate parametric scattering in non-resonantly driven coupled planar microcavities

open access: yesNanophotonics, 2021
Multi-level exciton-polariton systems offer an attractive platform for studies of non-linear optical phenomena. However, studies of such consequential non-linear phenomena as polariton condensation and lasing in planar microcavities have so far been ...

A discussion of deuterium excess production in rain water

open access: yesShui kexue jinzhan, 2012
Study on the characteristic of hydrogen and oxygen isotopes in precipitation is an important aspect of water cycle research.However,the production process of deuterium excess(D-excess) in rain water has not been fully explained.From the perspective of ...

Analytical framework for non-equilibrium phase transition to Bose–Einstein condensate

open access: yesQuantum, 2022
The theoretical description of non-equilibrium Bose–Einstein condensate (BEC) is one of the main challenges in modern statistical physics and kinetics. The non-equilibrium nature of BEC makes it impossible to employ the well-established formalism of statistical mechanics.
