A Universal Operator Growth Hypothesis
Daniel E. Parker, Xiangyu Cao, Alexander Avdoshkin +2
We present a hypothesis for the universal properties of operators evolving under Hamiltonian dynamics in many-body systems. The hypothesis states that successive Lanczos coefficien…
Equivalence of magnetic field and particle dilution in the strange metal state of CeCoIn
Nikola Maksimovic, Ian M. Hayes, Sooyoung Jang +3
The Bardeen-Cooper-Schrieffer mechanism for superconductivity is a triumph of the theory of many-body systems. Implicit in its formulation is the existence of long-lived (quasi)par…
Activating many-body localization in solids by driving with light
Zala Lenarčič, Ehud Altman, Achim Rosch
Due to the presence of phonons, many body localization (MBL) does not occur in disordered solids, even if disorder is strong. Local conservation laws characterizing an underlying M…
Field evolution of magnons in -RuCl by high-resolution polarized terahertz spectroscopy
Liang Wu, Arielle Little, Erik E. Aldape +13
The Kitaev quantum spin liquid (KSL) is a theoretically predicted state of matter whose fractionalized quasiparticles are distinct from bosonic magnons, the fundamental excitation…
On the stability of many-body localization in
Ionut-Dragos Potirniche, Sumilan Banerjee, Ehud Altman
Recent work by De Roeck et al. [Phys. Rev. B 95, 155129 (2017)] has argued that many-body localization (MBL) is unstable in two and higher dimensions due to a thermalization avalan…
Many-body localization, thermalization, and entanglement
Dmitry A. Abanin, Ehud Altman, Immanuel Bloch +1
Thermalizing quantum systems are conventionally described by statistical mechanics at equilibrium. However, not all systems fall into this category, with many body localization pro…
