Kac-Moody symmetries in one-dimensional bosonic systems
Wei Tang, Jutho Haegeman
In conformal field theories, when the conformal symmetry is enhanced by a global Lie group symmetry, the original Virasoro algebra can be extended to Kac-Moody algebra. In this pap…
Continuous matrix product operator approach to finite temperature quantum states
Wei Tang, Hong-Hao Tu, Lei Wang
We present an algorithm for studying quantum systems at finite temperature using continuous matrix product operator representation. The approach handles both short-range and long-r…
Quantized thermal Hall conductance from edge current calculations in lattice models
Wei Tang, X. C. Xie, Lei Wang +1
The quantized thermal Hall effect is an important probe for detecting chiral topological order and revealing the nature of chiral gapless edge states. The standard Kubo formula app…
Klein bottle entropy of compactified boson conformal field theory
Wei Tang, X. C. Xie, Lei Wang +1
We extend the scope of the Klein bottle entropy, originally introduced by [Tu, Phys. Rev. Lett. 119, 261603 (2017)] in the rational conformal field theory (CFT), to the compactifie…
Universal Boundary Entropies in Conformal Field Theory: A Quantum Monte Carlo Study
Wei Tang, Lei Chen, Wei Li +3
Recently, entropy corrections on nonorientable manifolds such as the Klein bottle are proposed as a universal characterization of critical systems with an emergent conformal field…
