Unified Probe of Quantum Chaos and Ergodicity from Hamiltonian Learning
Nik O. Gjonbalaj, Christian Kokail, Susanne F. Yelin +1
Developing measures of quantum ergodicity and chaos stands as a foundational task in the study of quantum many-body systems. In this work, we propose metrics for these effects base…
Fast computational deep thermalization
Shantanav Chakraborty, Soonwon Choi, Soumik Ghosh +1
Deep thermalization refers to the emergence of Haar-like randomness from quantum systems upon partial measurements. As a generalization of quantum thermalization, it is often assoc…
Critically Slow Hilbert-Space Ergodicity in Quantum Morphic Drives
Saúl Pilatowsky-Cameo, Soonwon Choi, Wen Wei Ho
The maximum entropy principle is foundational for statistical analyses of complex dynamics. This principle has been challenged by the findings of a previous work [arXiv:1701.07596]…
Quantum thermalization must occur in translation-invariant systems at high temperature
Saúl Pilatowsky-Cameo, Soonwon Choi
Quantum thermalization describes how closed quantum systems can effectively reach thermal equilibrium, resolving the apparent incongruity between the reversibility of Schrödinger's…
