On the origin of finite entanglement scaling
Luke Hodgkiss, Laurens Lootens, Atsushi Ueda +2
The paper identifies the actual perturbations introduced by matrix product state approximations of critical quantum systems, showing they differ from conformal field theory predict…
Symmetric mass generation of interacting chiral fermions on a one-dimensional lattice without fermion doubling
V. A. Zakharov, Atsushi Ueda, Frank Verstraete +1
Symmetric mass generation is the interaction-induced opening of a fermion gap without spontaneous symmetry breaking. The anomaly-free 3-4-5-0 model of Wang and Wen provides a minim…
Emergent Andreev Reflection from a Lattice Duality Defect
Atsushi Ueda, Tokiro Numasawa, Boris De Vos +1
Andreev reflection converts an incoming fermion into an outgoing hole and is usually tied to a superconducting interface. We show that an analogous charge-conjugating boundary cond…
Perfect Particle Transmission through Duality Defects
Atsushi Ueda, Vic Vander Linden, Laurens Lootens +3
We study wavepackets that propagate across (a) topological interfaces in quantum spin systems exhibiting non-invertible symmetries and (b) duality defects coupling dual theories. W…
Deconfinement from Thermal Tensor Networks: Universal CFT signature in (2+1)-dimensional lattice gauge theory
Adwait Naravane, Yuto Sugimoto, Shinichiro Akiyama +2
Tensor networks offer a sign-problem-free approach to study lattice gauge theories, but extracting precise universal information associated with the deconfinement transition remain…
Global Tensor Network Renormalization for 2D Quantum systems: A new window to probe universal data from thermal transitions
Atsushi Ueda, Sander De Meyer, Adwait Naravane +2
We propose a new tensor network renormalization group (TNR) scheme based on global optimization and introduce a new method for constructing the finite-temperature density matrix of…
