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…
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…
