Quantum oscillations in the hole-doped cuprates and the confinement of spinons

PM Bonetti, M Christos, S Sachdev - … of the National Academy of Sciences, 2024 - pnas.org
A long-standing problem in the study of the under-hole-doped cuprates has been the
description of the Fermi surfaces underlying the high magnetic field quantum oscillations …

Dynamics of glassy systems

LF Cugliandolo - arxiv preprint cond-mat/0210312, 2002 - Springer

Quantum-to-classical crossover in the spin glass dynamics of cavity QED simulators

H Hosseinabadi, DE Chang, J Marino - Physical Review Research, 2024 - APS
By solving the quench dynamics of a frustrated many-body spin-boson problem, we
investigate the role of spin size on the dynamical formation of spin-glass order. In particular …

Quantum mode-coupling theory: Formulation and applications to normal and supercooled quantum liquids
