Magnetic-texture winding controls fermion-parity switches in an interacting -wave magnet ring
Hyun-Yong Lee
Coplanar magnetic spirals map locally onto uniform spin--orbit-coupled wires, but on a ring the rotating spin frame can change the electronic boundary condition. We prove, level by…
Data-efficient reconstruction of critical quantum dynamics via blind fractional-envelope extrapolation
Hyunju Kim, Hyun-Yong Lee, Heung-Sik Kim
Simulating real-time dynamics of quantum systems is often limited to short times by entanglement growth. Finite-pole reconstructions such as linear prediction and related machineri…
Topological phase transition of deformed toric code
Yun-Tak Oh, Hyun-Yong Lee
The paper studies how deformations of the Z₃ toric-code wavefunction lead to topological phase transitions, mapping the problem to Potts and Ashkin‑Teller models and using tensor‑n…
Universal Information-Theoretic Structure of the Quasi-Stationary Domany--Kinzel Automaton
Hyun-Yong Lee, Kenji Harada, Naoki Kawashima
We characterize the quasi-stationary distribution (QSD) of the bond directed-percolation line of the Domany--Kinzel automaton using a matrix-product-state representation of the pro…
Spin-orbit-induced quantum chiral phases
Daesik Kim, Hyojae Jeon, Seongjun Park +3
The scalar spin chirality (SSC), whose nonzero value implies the breaking of time-reversal and certain point-g…
Projector, Neural, and Tensor-Network Representations of Cluster and Dipolar-cluster SPT States
Seungho Lee, Daesik Kim, Hyun-Yong Lee +1
The cluster-state wavefunction, a paradigmatic example of symmetry-protected topological (SPT) order with symmetry, is expressed i…
