The NCTS international summer school and workshop on emergent quantum many-body phenomena

Date: July 26-30, 2021 (Taiwan, GMT+8)

Format: online workshop

Introduction

The goal of this joint online* summer school and workshop is to bring together domestic and international experts on quantum condensed matter theory to discuss frontier research topics. The tutorial talks introduce these topics to graduate students and young researchers, while the in-depth talks give opportunities to research collaborations among domestic and international experts. The topics of this school/workshop include

[* Due to the current coronavirus pandemic]

Correlated quantum matter:

The correlated effect in quantum systems leads to intriguing properties of quantum correlated quantum matter such as quantum spin liquids, non-fermi liquids, and superconductivity. Quantum spin liquids are interesting from a fundamental point of view where the concept of entanglement, symmetry, and topology intertwined. At the same time, new theories, experiments, and numerical results of quantum spin liquids (experiments on Kitaev spin liquid materials and theoretical studies on gapless spin liquids) keep pushing the forefront in the study of quantum matter. Besides, the recent breakthrough on twisted two-dimensional materials opens the gate toward novel schemes to control the correlation effects.

Non-equilibrium quantum many-body systems:

When traditional many-body physics focused on equilibrium properties of quantum matter, numerous experimental developments have been made for exploring highly non-equilibrium quantum states in many novel systems recently. Ultrafast experimental techniques provide access to the real-time dynamics of quantum materials, including excitation and relaxation of quasiparticles and dynamical induction or suppression of order parameters. Another new development is the control and manipulation of synthetic quantum systems, which allow us to explore fundamental non-equilibrium physics, such as out-of-equilibrium critical phenomena and non-Hermitian physics. On the other hand, quantum information and the holography principle also bring new insights into understanding many-body quantum dynamics. The invited speakers will discuss recent theoretical developments in quantum thermalizations, quantum chaos, and entanglement spreading, dynamical quantum phase transitions, pump-probe systems, the interplay of topology and out-of-equilibrium dynamics, as well as thermalization and its breakdown in quantum systems.

This workshop/school aims to bring together several communities devoted to studying these different aspects of correlated and non-equilibrium quantum matter. We hope the event can inspire new ideas and reveal new connections between different aspects of quantum many-body physics.
