Digital Simulation of Non-Hermitian Knotted Bands on Quantum Hardware
Truman Yu Ng, Yuzhu Wang, Wei Jie Chan +3
Knots and links represent a fundamental motif of non-local connectivity that permeates the physical sciences from string theory to protein folds. While spectral braiding has been e…

Deterministic scale-invariant dynamics in a logistic Game-of-Life model
Hakan Akgun, Xianquan Yan, Tamer Taskiran +3
Scale invariance is a hallmark of criticality in complex dynamical systems. While random external inputs or tunable stochastic interactions are typically required to produce critic…

Nonlinear Hall effects with an exceptional ring
Fang Qin, Ruizhe Shen, Ching Hua Lee
In non-Hermitian band structures, exceptional points generically form gapless lines or loops that give rise to extensively many defective eigenstates. In this work, we investigate…
