The total geodesic curvature and the -dimensional hyperbolic mass
Xiaokai He, Xiaoning Wu, Naqing Xie
In this paper, we derive a novel geometric inequality involving the total geodesic curvature, serving as an analogue of the Brown-York mass in the setting of -dimensional gr…
Two-Polariton Blockade via Ultrastrong Light-Matter Coupling
Ting-Ting Ma, Jian Tang, Yun-Lan Zuo +3
We demonstrate that a two-polariton blockade (2PB) can occur under resonant single-polariton driving in an atom-cavity system operating in the ultrastrong coupling (USC) regime-a p…
Bondi Mass, Memory Effect and Balance Law of Polyhomogeneous Spacetime
Xiaokai He, Xiaoning Wu, Naqing Xie
Spacetimes with metrics admitting an expansion in terms of a combination of powers of 1/r and ln r are known as polyhomogeneous spacetimes. The asymptotic behaviour of the Newman-P…
Reinforcement learning assisted non-reciprocal optomechanical gyroscope
Qing-Shou Tan, Ya-Feng Jiao, Yunlan Zuo +3
We propose a novel optomechanical gyroscope architecture based on a spinning cavity optomechanical resonator (COM) evanescently coupled to a tapered optical fiber without relying o…
Quantum information flow in impurity qubits interacting with Bose-Bose mixtures
Abdelaali Boudjemaa, Lan Xu, Qing-Shou Tan
We investigate the dynamics of quantum information flow in one and two impurity qubits trapped in a double-well potential and interacting with a one-dimensional ultracold Bose-Bose…
Combinatorial Calabi flow for ideal circle pattern
Shengyu Li, Zhigang Wang
We study the combinatorial Calabi flow for ideal circle patterns in both hyperbolic and Euclidean background geometry. We prove that the flow exists for all time and converges expo…
