Exponential thermal tensor network approach for quantum lattice models
We speed up thermal simulations of quantum many-body systems in both one-(1D) and two-
dimensional (2D) models in an exponential way by iteratively projecting the thermal density …

Universal entropy of conformal critical theories on a Klein bottle
HH Tu - Physical review letters, 2017 - APS
We show that rational conformal field theories in 1+ 1 dimensions on a Klein bottle, with a
length L and width β, satisfying L≫ β, have a universal entropy. This universal entropy …

Extracting the Luttinger parameter from a single wave function
The low-energy physics of Tomonaga-Luttinger liquids (TLLs) is controlled by the Luttinger
parameter. We demonstrate that this parameter can be extracted from a single wave function …
