Two-temperature scales in the triangular-lattice Heisenberg antiferromagnet

Lei Chen, Dai-Wei Qu, Han Li +5

The anomalous thermodynamic properties of the paradigmatic frustrated spin-1/2 triangular lattice Heisenberg antiferromagnet (TLH) has remained an open topic of research over decad…

Topological and Geometric Universal Thermodynamics in Conformal Field Theory

Hao-Xin Wang, Lei Chen, Hai Lin +1

Universal thermal data in conformal field theory (CFT) offer a valuable means for characterizing and classifying criticality. With improved tensor network techniques, we investigat…

Exponential Thermal Tensor Network Approach for Quantum Lattice Models

Bin-Bin Chen, Lei Chen, Ziyu Chen +2

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 m…

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…

Conformal Thermal Tensor Network and Universal Entropy on Topological Manifolds

Lei Chen, Hao-Xin Wang, Lei Wang +1

Partition functions of quantum critical systems, expressed as conformal thermal tensor networks, are defined on various manifolds which can give rise to universal entropy correctio…

Bilayer Linearized Tensor Renormalization Group Approach for Thermal Tensor Networks

Yong-Liang Dong, Lei Chen, Yun-Jing Liu +1

In this paper, we perform a comprehensive study of the renormalization group (RG) method on thermal tensor networks (TTN). By Trotter-Suzuki decomposition, one obtains the 1+1D TTN…
