Quantum quench dynamics of the Bose-Hubbard model at finite temperatures
, 2011 We study quench dynamics of the Bose-Hubbard model by exact diagonalization. Initially the system is at thermal equilibrium and of a finite temperature. The system is then quenched by changing the on-site interaction strength $U$ suddenly.

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.The stability criteria affecting the formation of high‐entropy alloys, particularly focusing in supersaturated solid solutions produced by mechanical alloying, are analyzed. Criteria based on Hume–Rothery rules are distinguished from those derived from thermodynamic relations. The formers are generally applicable to mechanically alloyed samples.

Investigating the effect of heat treatment on the fatigue behavior of casting aluminum bronze containing nickel, iron and manganese [PDF]
Fanāvarī-i āmūzish, 2007 Solution heat treatment followed by Quench and return is one of the important processes in the production of cast aluminum aluminum castings and significantly improves the microscopic structure and mechanical properties and changes the temperature of the

Aligning thermal and current quenches with a high density low-Z injection
Nuclear FusionThe conventional approach for thermal quench (TQ) mitigation in a tokamak disruption is through a high- Z impurity injection that radiates away the plasma’s thermal energy before it reaches the wall.

Thermal shock resistance of ceramic fibre composites characterized by non-destructive methods [PDF]
Processing and Application of Ceramics, 2008 Alumina based ceramic fibres and alumina based ceramic were used to produce composite material. Behaviour of composite ceramics after thermal shock treatments was investigated. Thermal shock of the samples was evaluated using water quench test.

Handbook of Establishing and Maintaining Oxygen‐Free Atmospheres
Advanced Engineering Materials, EarlyView.This study presents a practical framework for creating oxygen‐free atmospheres at ambient pressure using silane‐doped inert gases. The results show that ultra‐low oxygen levels and strongly reduced water content can be achieved through controlled silane dosing, drying systems, and sensor monitoring.

Validation of a Coupled Thermal-Electromagnetic Quench model for Accelerator Magnets [PDF]
, 2007 Quench simulation in superconducting magnets is a challenging task due to the interdependence of thermal, electrical, and magnetic phenomena. We present a new quench-simulation module in the CERN magnet-design program ROXIE.

Universality of fast quenches from the conformal perturbation theory
Journal of High Energy Physics, 2018 We consider global quantum quenches, a protocol when a continuous field theoretic system in the ground state is driven by a homogeneous time-dependent external interaction.

Dileptons from Disoriented Chiral Condensates [PDF]
, 1997 Disoriented chiral condensates or long wavelength pionic oscillations and their interaction with the thermal environment can be a significant source of dileptons. We calculate the yield of such dilepton production within the linear sigma model, both in a
