• Abstract: Understanding how an isolated quantum system evolves toward a thermal state from an initial state far from equilibrium such as one prepared by a global quantum quench has attracted significant interest in recent years. This phenomenon can be elucidated through the Eigenstate Thermalization Hypothesis (ETH), which has had a profound impact across various fields, from high-energy physics to condensed matter physics. The purpose of this review article is to present the fundamental concepts of quantum equilibrium and the ETH to a broad audience within the physics community, particularly for those in high-energy physics who seek a comprehensive understanding of these important topics.

• The quantum Mpemba effects [0.0]
  The Mpemba effect, where a hotter system can equilibrate faster than a cooler one, has long been a subject of fascination in classical physics. We provide a concise overview of the Mpemba effect in quantum systems, with a focus on both open and isolated dynamics. Particular attention is given to the role of quantum fluctuations, integrability, and symmetry in shaping equilibration pathways.
