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…
