Transition between heavy-fermion strange metal and quantum spin liquid in a 4d-electron trimer lattice
Hengdi Zhao, Yu Zhang, Pedro Schlottmann +2
We present experimental evidence that a heavy Fermi surface consisting of itinerant, charge-neutral spinons underpins both heavy-fermion-strange-metal (without f electrons) and qua…
Topologically stable ergodicity breaking from emergent higher-form symmetries in generalized quantum loop models
Charles Stahl, Rahul Nandkishore, Oliver Hart
We present a set of generalized quantum loop models which provably exhibit topologically stable ergodicity breaking. These results hold for both periodic and open boundary conditio…
Fracton superfluid hydrodynamics
Charles Stahl, Marvin Qi, Paolo Glorioso +2
We examine the hydrodynamics of systems with spontaneously broken multipolar symmetries using a systematic effective field theory. We focus on the simplest non-trivial setting: a s…
Multipole groups and fracton phenomena on arbitrary crystalline lattices
Daniel Bulmash, Oliver Hart, Rahul Nandkishore
Multipole symmetries are of interest in multiple contexts, from the study of fracton phases, to nonergodic quantum dynamics, to the exploration of new hydrodynamic universality cla…
Non-local finite-depth circuits for constructing SPT states and quantum cellular automata
David T. Stephen, Arpit Dua, Ali Lavasani +1
Whether a given target state can be prepared by starting with a simple product state and acting with a finite-depth quantum circuit is a key question in condensed matter physics an…
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…
