Hilbert-Space Fragmentation from Strict Confinement
Zhi-Cheng Yang, Fangli Liu, Alexey V. Gorshkov +1
We study one-dimensional spin-1/2 models in which strict confinement of Ising domain walls leads to the fragmentation of Hilbert space into exponentially many disconnected subspace…
Real-time dynamics of string breaking in quantum spin chains
Roberto Verdel, Fangli Liu, Seth Whitsitt +2
String breaking is a central dynamical process in theories featuring confinement, where a string connecting two charges decays at the expense of the creation of new particle-antipa…
Momentum-space entanglement after a quench in one-dimensional disordered fermionic systems
Rex Lundgren, Fangli Liu, Pontus Laurell +1
We numerically investigate the momentum-space entanglement entropy and entanglement spectrum of the random-dimer model and its generalizations, which circumvent Anderson localizati…
Circuit Complexity across a Topological Phase Transition
Fangli Liu, Seth Whitsitt, Jonathan B. Curtis +5
We use Nielsen's geometric approach to quantify the circuit complexity in a one-dimensional Kitaev chain across a topological phase transition. We find that the circuit complexitie…
