Signature of Many-Body Localization of Phonons in Strongly Disordered Superlattices
Thanh Nguyen, Nina Andrejevic, Hoi Chun Po +17
Many-body localization (MBL) has attracted significant attention due to its immunity to thermalization, role in logarithmic entanglement entropy growth, and opportunities to reach…
Signature of a polyamorphic transition in the THz spectrum of vitreous GeO2
Alessandro Cunsolo, Yan Li, Chaminda N. Kodituwakku +10
The THz spectrum of density fluctuations, , of vitreous GeO at ambient temperature was measured by inelastic x-ray scattering from ambient pressure up to pressures wel…
Thermally triggered phononic gaps in liquids at THz scale
Dima Bolmatov, Mikhail Zhernenkov, Dmitry Zav'yalov +3
In this paper we present inelastic X-ray scattering experiments in a diamond anvil cell and molecular dynamic simulations to investigate the behavior of phononic excitations in liq…
Revealing the Mechanism of the Viscous-to-Elastic Crossover in Liquids
Dima Bolmatov, Mikhail Zhernenkov, Dmitry Zavyalov +3
In this work, we report on inelastic X-ray scattering experiments combined with the molecular dynamics simulations on deeply supercritical Ar. The presented results unveil the mech…
Unified phonon-based approach to the thermodynamics of solid, liquid and gas states
Dima Bolmatov, Dmitry Zavyalov, Mikhail Zhernenkov +2
We introduce a unified approach to states of matter (solid, liquid and gas) and describe the thermodynamics of the pressure-temperature phase diagram in terms of phonon excitations…
Ultra high energy resolution focusing monochromator for inelastic X-ray scattering spectrometer
A. Suvorov, A. Cunsolo, O. Chubar +1
A further development of a focusing monochromator concept for X-ray energy resolution of 0.1 meV and below is presented. Theoretical analysis of several optical layouts based on th…
