Quantum Many-Body Scars from Einstein-Podolsky-Rosen States in Bilayer Systems
Julia Wildeboer, Christopher M. Langlett, Zhi-Cheng Yang +3
Quantum many-body scar states are special eigenstates of nonintegrable models with distinctive entanglement features that give rise to infinitely long-lived coherent dynamics under…
Rainbow Scars: From Area to Volume Law
Christopher M. Langlett, Zhi-Cheng Yang, Julia Wildeboer +3
Quantum many-body scars (QMBS) constitute a new quantum dynamical regime in which rare "scarred" eigenstates mediate weak ergodicity breaking. One open question is to understand th…
Localization and criticality in antiblockaded 2D Rydberg atom arrays
Fangli Liu, Zhi-Cheng Yang, Przemyslaw Bienias +2
Controllable Rydberg atom arrays have provided new insights into fundamental properties of quantum matter both in and out of equilibrium. In this work, we study the effect of exper…
Tunable Fragile Topology in Floquet Systems
Rui-Xing Zhang, Zhi-Cheng Yang
We extend the notion of fragile topology to periodically-driven systems. We demonstrate driving-induced fragile topology in two different models, namely, the Floquet honeycomb mode…
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…
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…
Hierarchical Majoranas in a Programmable Nanowire Network
Zhi-Cheng Yang, Thomas Iadecola, Claudio Chamon +1
We propose a hierarchical architecture for building "logical" Majorana zero modes using "physical" Majorana zero modes at the Y-junctions of a hexagonal network of semiconductor na…
