Entanglement Properties of the One-Dimensional Dimerized Fermi-Hubbard Model
Min-Chul Cha, Hoon Beom Kwon, Ji-Woo Lee +1
We study the entanglement properties of the one-dimensional dimerized Fermi-Hubbard model. Using a matrix-product-state approach, we compute the ground state and identify two insul…
Entanglement entropy of two-species hard-core bosons in one dimension
Tae Yong Kim, Hang Gon Cho, Ji-Woo Lee
We study the von Neumann entropy of a model for two-species hard-core bosons in one dimension. In this model, the same-species bosons satisfy hard-core conditions, while the differ…
Directional current-current correlation functions in a two-species hard-core bosons in one dimensional finite lattice: An exact diagonalization study
Ji-Woo Lee
We study a model for two-species hard-core bosons in one dimension. In this model, the same-species bosons have a hard-core condition at the same site, while different-species boso…
Finite-temperature phase transitions in a two-dimensional boson Hubbard model
Min-Chul Cha, Ji-Woo Lee
We study finite-temperature phase transitions in a two-dimensional boson Hubbard model with zero-point quantum fluctuations via Monte Carlo simulations of quantum rotor model, and…
Disorder-Induced Superfluidity in Hardcore Bosons in Two Dimensions
Ji-Woo Lee, Shailesh Chandrasekharan, Harold U. Baranger
We study the effect of disorder on hardcore bosons in two dimensions at the SU(2) symmetric ``Heisenberg point''. We obtain our results with quantum Monte Carlo simulations using t…
Quantum Phase Transitions of Hard-Core Bosons in Background Potentials
Anand Priyadarshee, Shailesh Chandrasekharan, Ji-Woo Lee +1
We study the zero temperature phase diagram of hard core bosons in two dimensions subjected to three types of background potentials: staggered, uniform, and random. In all three ca…
