Probing fractional statistics in quantum simulators of spin liquid Hamiltonians
Shiyu Zhou, Maria Zelenayova, Oliver Hart +2
Recent advances in programmable quantum devices brought to the fore the intriguing possibility of using them to realise and investigate topological quantum spin liquid phases. This…
Ergodicity breaking provably robust to arbitrary perturbations
David T. Stephen, Oliver Hart, Rahul M. Nandkishore
We present a new route to ergodicity breaking via Hilbert space fragmentation that displays an unprecedented level of robustness. Our construction relies on a single emergent (pret…
Measurement-induced phases of matter require feedback
Aaron J. Friedman, Oliver Hart, Rahul Nandkishore
We explore universality and phases of matter in hybrid quantum dynamics combining chaotic time evolution and projective measurements. We develop a unitary representation of measure…
Extracting spinon self-energies from two-dimensional coherent spectroscopy
Oliver Hart, Rahul Nandkishore
Two-dimensional coherent spectroscopy (2DCS) is a nonlinear spectroscopy technique capable of identifying whether apparent continua in linear response are made out of multiplets of…
Fracton magnetohydrodynamics
Marvin Qi, Oliver Hart, Aaron J. Friedman +2
We extend recent work on hydrodynamics with global multipolar symmetries -- known as "fracton hydrodynamics" -- to systems in which the multipolar symmetries are gauged. We refer t…
Hilbert space shattering and dynamical freezing in the quantum Ising model
Oliver Hart, Rahul Nandkishore
We discuss quantum dynamics in the transverse field Ising model in two spatial dimensions. We show that, up to a prethermal timescale, which we quantify, the Hilbert space 'shatter…
Effects of critical correlations on quantum percolation in two dimensions
Giuseppe De Tomasi, Oliver Hart, Cecilie Glittum +1
We analyze the out-of-equilibrium dynamics of a quantum particle coupled to local magnetic degrees of freedom that undergo a classical phase transition. Specifically, we consider a…
