On the Ising/tricritical-Ising interface: From symmetry to Rydberg atoms
António Antunes, Junchen Rong
We consider interfaces between critical spin-chains in different universality classes, described in the continuum limit by defect/interface conformal field theory (DCFT/ICFT). We f…
Numerical evidence of a critical point in the (2+1)D SO(5) nonlinear sigma model with Wess-Zumino-Witten term
Yuan Da Liao, Bin-Bin Chen, Junchen Rong +3
We develop an optimized continuous-field quantum Monte Carlo (QMC) algorithm to investigate the projected SO(5) nonlinear sigma model with a Wess-Zumino-Witten term, which describe…
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…
Phase transitions and remnants of fractionalization at finite temperature in the triangular lattice quantum loop model
Xiaoxue Ran, Sylvain Capponi, Junchen Rong +2
The quantum loop and dimer models are archetypal correlated systems with local constraints. With natural foundations in statistical mechanics, they are of direct relevance to vario…
UV complete local field theory of persistent symmetry breaking in 2+1 dimensions
Bilal Hawashin, Junchen Rong, Michael M. Scherer
Spontaneous symmetry breaking can persist at all temperatures in certain biconical vector models when the underlying field theories are ultraviol…
Surface phase transitions in a (1+1)-dimensional conformal field theory boundary coupled to a (2+1)-dimensional bulk
Zhe Wang, Shang-Qiang Ning, Zenan Liu +4
We design a (2+1))-dimensional [(2+1)D] quantum spin model in which spin-1/2 ladders are coupled through antiferromagnetic Ising interactions. The model hosts a quantum phase trans…
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…
