Toy models of black hole, white hole and wormhole: thermal effects and information loss problem
Yu-Zhu Chen, Shi-Lin Li, Yu-Jie Chen +2
In this paper, by setting proper boundaries in the Minkowski spacetime, we construct three toy model spacetimes, a toy black hole, a toy white hole, and a toy wormhole. Based on th…
Can Sophisticated Dispatching Strategy Acquired by Reinforcement Learning? - A Case Study in Dynamic Courier Dispatching System
Yujie Chen, Yu Qian, Yichen Yao +5
In this paper, we study a courier dispatching problem (CDP) raised from an online pickup-service platform of Alibaba. The CDP aims to assign a set of couriers to serve pickup reque…
A Highly Adjustable Helical Beam: Design and Propagation Characteristic
Yuanhui Wen, Yujie Chen, Siyuan Yu
Light fields with extraordinary propagation behaviours such as nondiffracting and self-bending are useful in optical delivery for energy, information, and even objects. A kind of h…
Tailoring Accelerating Beams in Phase Space
Yuanhui Wen, Yujie Chen, Yanfeng Zhang +2
An appropriate design of wavefront will enable light fields propagating along arbitrary trajectories thus forming accelerating beams in free space. Previous ways of designing such…
Transport properties of photonic topological insulators based on microring resonator array
Xiaohui Jiang, Yujie Chen, Chenxuan Yin +3
An array of ring resonators specifically designed can perform as a topological insulator. We conduct simulations using both Tight-Binding Model (TBM) and Transfer Matrix Method (TM…
Winding light beams along elliptical helical trajectories
Yuanhui Wen, Yujie Chen, Yanfeng Zhang +2
Conventional caustic methods in real or Fourier space produced accelerating optical beams only with convex trajectories. We develop a superposition caustic method capable of windin…
