Quantum Pontus-Mpemba Effects in Real and Imaginary-time Dynamics
Hui Yu, Jiangping Hu, Shi-Xin Zhang
The quantum Pontus-Mpemba effect (QPME) is a counterintuitive phenomenon wherein a quantum system relaxes more rapidly through a two-step evolution protocol than through direct evo…
TensorCircuit-NG: A Universal, Composable, and Scalable Platform for Quantum Computing and Quantum Simulation
Shi-Xin Zhang, Yu-Qin Chen, Weitang Li +22
We present TensorCircuit-NG, a next-generation quantum software platform designed to bridge the gap between quantum physics, artificial intelligence, and high-performance computing…
Symmetry Breaking Dynamics in Quantum Many-Body Systems
Hui Yu, Zi-Xiang Li, Shi-Xin Zhang
Entanglement asymmetry has emerged as a powerful tool for characterizing symmetry breaking in quantum many-body systems. In this Letter, we explore how symmetry is dynamically brok…
Quantum Mpemba Effects from Symmetry Perspectives
Hui Yu, Shuo Liu, Shi-Xin Zhang
Non-equilibrium dynamics have become a central research focus, exemplified by the counterintuitive Mpemba effect where initially hotter systems can cool faster than colder ones. St…
Hilbert subspace imprint: a new mechanism for non-thermalization
Hui Yu, Jiangping Hu, Shi-Xin Zhang
The search for non-ergodic mechanisms in quantum many-body systems has become a frontier area of research in non-equilibrium physics. In this Letter, we introduce Hilbert subspace…
