Extracting central charge from ground-state overlaps of spatially deformed Hamiltonians
Chen Bai, Xinyu Sun, Liang-Hong Mo +1
We show that the conformal anomaly of a -dimensional conformal field theory can be extracted directly from a ground-state wave-function overlap associated with a spatial con…
Efficient simulation of low-entanglement bosonic Gaussian states in polynomial time
Tong Liu, Hui-Ke Jin, Tao Xiang +1
Bosonic Gaussian states are ubiquitous in quantum optics and condensed matter physics. While they are efficiently handled within the Gaussian formalism, sampling requires calculati…
Revisiting the - Heisenberg Model on a Triangular Lattice: Quasi-Degenerate Ground States and Phase Competition
Oleksandra Kovalska, Ester Pagès Fontanella, Benedikt Schneider +2
It is generally believed that the spin- triangular-lattice - Heisenberg model hosts a quantum spin liquid in the intermediate regime between the …
A Promising Method for Strongly Correlated Electrons in Two Dimensions: Gutzwiller-Guided Density Matrix Renormalization Group
Hui-Ke Jin, Rong-Yang Sun, Hong-Hao Tu +1
The study of strongly correlated electron systems remains a fundamental challenge in condensed matter physics, particularly in two-dimensional (2D) systems hosting various exotic p…
Dirac and chiral spin liquids on spin-1/2 square-lattice Heisenberg antiferromagnet
Hui-Ke Jin, Hong-Hao Tu, Ya-Hui Zhang
We revisit the challenging problem of identifying the quantum spin liquid candidate in the spin-1/2 - Heisenberg antiferromagnet on the square lattice. By integrating the…
