Noise Balance and Stationary Distribution of Stochastic Gradient Descent
Liu Ziyin, Hongchao Li, Masahito Ueda
The stochastic gradient descent (SGD) algorithm is the algorithm we use to train neural networks. However, it remains poorly understood how the SGD navigates the highly nonlinear a…
Resonance-dominant optomechanical entanglement in open quantum systems
Cheng Shang, Hongchao Li
Motivated by entanglement protection, our work utilizes a resonance effect to enhance optomechanical entanglement in the coherent-state representation. We propose a filtering model…
Yang-Lee Zeros, Semicircle Theorem, and Nonunitary Criticality in Bardeen-Cooper-Schrieffer Superconductivity
Hongchao Li, Xie-Hang Yu, Masaya Nakagawa +1
Yang and Lee investigated phase transitions in terms of zeros of partition functions, namely, Yang-Lee zeros [Phys. Rev. 87, 404 (1952); Phys. Rev. 87, 410 (1952)]. We show that th…
Renormalization group analysis on emergence of higher rank symmetry and higher moment conservation
Hongchao Li, Peng Ye
Higher rank symmetry and higher moment conservation have been drawn considerable attention from, e.g., subdiffusive transport to fracton topological order. In this paper, we perfor…
Quantum Kinetic Theory of Nonlinear Nernst Effect
Hongchao Li
For a long period of time, we have been seeking how Berry curvature influnces the transport properties in materials breaking time-reversal symmetry. In time-reversal symmetric mate…
