Journal of High Energy Physics, 2021 Traversing a continuous phase transition at a finite rate leads to the breakdown of adiabatic dynamics and the formation of topological defects, as predicted by the celebrated Kibble-Zurek mechanism (KZM).

Critical quenches, OTOCs and early-time chaos
Journal of High Energy Physics, 2022 In this article, we explore dynamical aspects of Out-of-Time-Order correlators (OTOCs) for critical quenches, in which an initial non-trivial state evolves with a CFT-Hamiltonian.

Phases of quench dynamics in the presence of fluctuations
Physical Review Research, 2023 We study the effect of thermal fluctuations on a sourced quench in a system with Z_{2} symmetry. By ignoring the fluctuation of finite momentum modes and tracing the dynamics of zero momentum mode driven by a spatially homogeneous source near the ...

MHD modeling of shattered pellet injection in JET
Nuclear Fusion, 2023 Nonlinear 3D MHD simulations of shattered-pellet injection (SPI) in JET show prototypical SPI-driven disruptions using the M3D-C1 and NIMROD extended-MHD codes.

Quantum quenches and thermalization in SYK models [PDF]
Journal of High Energy Physics, 2019 AbstractWe study non-equilibrium dynamics in SYK models using quantum quench. We consider models with two, four, and higher fermion interactions (q= 2,4, and higher) and use two different types of quench protocol, which we call step and bump quenches. We analyse evolution of fermion two-point functions without long time averaging.

Inhomogeneous thermal quenches [PDF]
Physical Review D, 2017 We describe holographic thermal quenches that are inhomogeneous in space. The main characteristic of the quench is to take the system far from its equilibrium configuration. Except special extreme cases, the problem has no analytic solution. Using the numerical holography methods, we study different observables that measure thermalization such as the ...

Transient response of an electrolyte to a thermal quench [PDF]
Physical Review E, 2019 We study the transient response of an electrolytic cell subject to a small, suddenly applied temperature increase at one of its two bounding electrode surfaces. An inhomogeneous temperature profile then develops, causing, via the Soret effect, ionic rearrangements towards a state of polarized ionic charge density $q$ and local salt density $c$. For the

Journal of High Energy Physics, 2019 A macroscopic version of Einstein-Podolsky-Rosen entanglement is obtained by quenching a quadratic coupling between two O(N) vector models. A quench of the mixed vacuum produces an excited entangled state, reminiscent of purified thermal equilibrium ...

New Journal of Physics, 2022 The topological phase of the Su–Schrieffer–Heeger (SSH) model is known to exhibit two edge states that are topologically protected by the chiral symmetry. We demonstrate that, for any parameter quench performed on the half-filled SSH chain, the occupancy
