Abstract: We investigate the dynamics of quantum scrambling, characterized by the out-of-time ordered correlators (OTOCs), in a non-Hermitian quantum kicked rotor subjected to quasi-periodical modulation in kicking potential. Quasi-periodic modulation with incommensurate frequencies creates a high-dimensional… read more here.

DOI: 10.1016/j.molliq.2019.02.088
Abstract: Abstract We present results from molecular dynamics simulations of a solution of water and trehalose, a cryoprotecting disaccharide, upon cooling. We focus our attention on both the dynamics of hydration water and of the trehalose.… read more here.

Abstract: We present a model of the dynamical transition of atomic displacements in proteins. Increased mean-square displacement at higher temperatures is caused by the softening of the force constant for atomic/molecular displacements by electrostatic and van… read more here.

DOI: 10.1103/physrevd.110.084011
Abstract: We analyze numerically the dynamical transition to spontaneous scalarization in neutron stars in the framework of a scalar-tensor theory of gravity where the scalar field is free but massive, and it is coupled nonminimally to… read more here.

DOI: 10.1515/bmc-2022-0007
Abstract: Abstract Hydration of water affects the dynamics and in turn the activity of biomacromolecules. We investigated the dependence of the librational oscillations and the dynamical transition on the hydrating conditions of two globular proteins with… read more here.
