Numerical Study of Stability of Clean Critical Points across Aperiodic, Topological, and Uncorrelated Disorder
Shuhao Fan, Lu Liu, Wenan Guo
Using the two-dimensional Ashkin-Teller (AT) model, we compare criticality on three non-periodic lattices: the Smith-hat aperiodic tiling, Voronoi-Delaunay (VD) random triangulatio…
Edge modes of topological Mott insulators and deconfined quantum critical points
Yuhai Liu, Toshihiro Sato, Disha Hou +3
Topology and anomalies lead to edge modes that can interact with critical bulk fluctuations. To study this setup, pertaining to boundary criticality, we consider a model exhibiting…
Detecting underlying symmetry-protected topological phases via strange correlators and edge engineering
Zhe Wang, Longye Lu, Shang-Qiang Ning +4
The vast majority of symmetry-protected topological (SPT) states are difficult to detect, which often leads to their misidentification as ordinary or topologically trivial phases.…
Coplanar order induced by emergent frustration
Zehui Deng, Lu Liu, Wenan Guo +1
Traditional frustration arises from the conflict between the spin alignments due to the geometry or the nature of the interactions. Here, we demonstrate a novel form of frustration…
Field-induced phase transitions in the Kitaev-Heisenberg model: A sign-problem-free quantum Monte Carlo study and possible application to -RuCl3
Xuan Zou, Shuo Liu, Wenan Guo +1
The frustrated magnet -RuCl3 is one of the prime candidates for realizing a Kitaev quantum spin liquid (QSL). However, the existence of a field-induced intermediate QSL phase in…
Universal Behavior in Entanglement Entropy Reveals Quantum Criticality and Underlying Symmetry Breaking
Zhe Wang, Zehui Deng, Zenan Liu +5
Entanglement plays a key role in quantum physics, but how much information it can extract from many-body systems is still an open question, particularly regarding quantum criticali…
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…
