Grand Canonical-like Thermalization of Quantum Many-body Scars
Jia-wei Wang, Xiang-Fa Zhou, Guang-Can Guo +1
Quantum many-body scar (QMBS) in kinetically constrained quantum systems challenges the conventional eigenstate thermalization hypothesis (ETH). We develop an effective open-system…
Broadband Population Transfer Based on Suture Adiabatic Pulses
Jiaming Li, Xi-Wang Luo, Guang-Can Guo +1
High-fidelity coherent population transfer plays a vital role in the realization of quantum memories. However, population transfer with high performance across a broad frequency ra…
Thermalization of Quantum Many-Body Scars in Kinetically Constrained Systems
Jia-wei Wang, Xiang-Fa Zhou, Guang-Can Guo +1
The phenomenon of quantum many-body scars (QMBS) has been studied both theoretically and experimentally, due to its unusual violation of the eigenstate thermalization hypothesis (E…
Tunable Antichiral Hinge State in Photonic Synthetic Dimensions
Xian-Hao Wei, Xi-Wang Luo, Mu Yang +4
Recent research in 2-dimensional (2D) topological matter has generalized the notion of edge states from chiral to antichiral configurations with the same propagating direction at p…
Higher-order Topological Parity Anomaly and Half-integer Hall Effect in High-dimensional Synthetic Lattices
Xian-Hao Wei, Xi-Wang Luo, Guang-Can Guo +1
Recent advances in constructing synthetic dimension provide a powerful tool for exploring exotic topological states of matter in high dimensions. Here we report that the parity ano…
Enhancing analogue Unruh effect via superradiance in a cylindrical cavity
Hong-Tao Zheng, Xiang-Fa Zhou, Guang-Can Guo +1
We propose a scheme to detect the Unruh effect in a circularly rotated Unruh-DeWitt detector enclosed within a cylindrical cavity. This technique relies on the enhanced atomic spon…
