Exact Quantum Many-Body Scar States in the Rydberg-Blockaded Atom Chain
Cheng-Ju Lin, Olexei I. Motrunich
A recent experiment in the Rydberg atom chain observed unusual oscillatory quench dynamics with a charge density wave initial state, and theoretical works identified a set of many-…
Ising ferromagnet to valence bond solid transition in a one-dimensional spin chain: Analogies to deconfined quantum critical points
Shenghan Jiang, Olexei I. Motrunich
We study a one-dimensional (1d) system that shows many analogies to proposed two-dimensional (2d) deconfined quantum critical points (DQCP). Our system is a translationally invaria…
Out-of-time-ordered correlators in short-range and long-range hard-core boson models and in the Luttinger-liquid model
Cheng-Ju Lin, Olexei I. Motrunich
We study out-of-time-ordered correlators (OTOC) in hard-core boson models with short-range and long-range hopping and compare the results to the OTOC in the Luttinger liquid model.…
Numerical exploration of trial wave functions for the particle-hole-symmetric Pfaffian
Ryan V. Mishmash, David F. Mross, Jason Alicea +1
We numerically assess model wave functions for the recently proposed particle-hole-symmetric Pfaffian (`PH-Pfaffian') topological order, a phase consistent with the recently report…
Out-of-time-ordered correlators in quantum Ising chain
Cheng-Ju Lin, Olexei I. Motrunich
Out-of-time-ordered correlators (OTOC) have been proposed to characterize quantum chaos in generic systems. However, they can also show interesting behavior in integrable models, r…
