Precise computation of universal corner entanglement entropy at 2+1 dimension: From Ising to Gaussian quantum critical points
Ben Lee-Yeung Ngai, Justin Tim-Lok Chau, Junchen Rong +3
Computing the subleading logarithmic term in the entanglement entropy (EE) of (2+1)d quantum many-body systems remains a significant challenge, despite its central role in revealin…
Extracting subleading corrections in entanglement entropy at quantum phase transitions
Menghan Song, Jiarui Zhao, Zi Yang Meng +2
We systematically investigate the finite size scaling behavior of the Rényi entanglement entropy (EE) of several representative 2d quantum many-body systems between a subregion and…
Evolution of entanglement entropy at SU() deconfined quantum critical points
Menghan Song, Jiarui Zhao, Meng Cheng +4
Over the past two decades, the enigma of the deconfined quantum critical point (DQCP) has attracted broad attention across the condensed matter, quantum field theory, and high-ener…
Fermion disorder operator at Gross-Neveu and deconfined quantum criticalities
Zi Hong Liu, Weilun Jiang, Bin-Bin Chen +5
The fermion disorder operator has been shown to reveal the entanglement information in 1D Luttinger liquids and 2D free and interacting Fermi and non-Fermi liquids emerging at quan…
Many versus one: the disorder operator and entanglement entropy in fermionic quantum matter
Weilun Jiang, Bin-Bin Chen, Zi Hong Liu +5
Motivated by recent development of the concept of the disorder operator and its relation with entanglement entropy in bosonic systems, here we show the disorder operator successful…
Exactly solvable lattice models for interacting electronic insulators in two dimensions
Qing-Rui Wang, Yang Qi, Chen Fang +2
In the past decade, tremendous efforts have been made towards understanding fermionic symmetry protected topological (FSPT) phases in interacting systems. Nevertheless, for systems…
