Schwinger effect of a relativistic boson entangled with a qubit
Yujie Li, Yu Shi
We use the concept of quantum entanglement to analyze the Schwinger effect on an entangled state of a qubit and a bosonic mode coupled with the electric field. As a consequence of…
Wilson line networks in -adic AdS/CFT
Ling-Yan Hung, Wei Li, Charles M. Melby-Thompson
The -adic AdS/CFT is a holographic duality based on the -adic number field . For a -adic CFT living on and with complex-valued fields, the bul…
Notes on the Causal Structure in a Tensor Network
Arpan Bhattacharyya, Long Cheng, Ling-Yan Hung +2
In this paper we attempt to understand Lorentzian tensor networks, as a preparation for constructing tensor networks that can describe more exotic backgrounds such as black holes.…
Entanglement Entropy of Topological Orders with Boundaries
Chaoyi Chen, Ling-Yan Hung, Yingcheng Li +1
In this paper we explore how non trivial boundary conditions could influence the entanglement entropy in a topological order in 2+1 dimensions. Specifically we consider the special…
Linking Entanglement and Discrete Anomaly
Ling-Yan Hung, Yong-Shi Wu, Yang Zhou
In Chern-Simons theory, there is a discrete one-form symmetry, whose symmetry group is isomorphic to the center of the gauge group. We study the 't Hooft anomaly associated to…
