Spontaneous breaking of multipole symmetries
Charles Stahl, Ethan Lake, Rahul Nandkishore
Multipole symmetries are of interest both as a window on fracton physics and as a crucial ingredient in realizing new universality classes for quantum dynamics. Here we address the…
Hidden quasiconservation laws in fracton hydrodynamics
Oliver Hart, Andrew Lucas, Rahul Nandkishore
We show that the simplest universality classes of fracton hydrodynamics in more than one spatial dimension, including isotropic theories of charge and dipole conservation, can exhi…
Multidome superconductivity in charge density wave kagome metals
Yu-Ping Lin, Rahul M. Nandkishore
Motivated by recent experiments on the kagome metals with , , and , which show a charge density wave (CDW) at K…
Spectroscopic fingerprints of gapless type-II fracton phases
Oliver Hart, Rahul Nandkishore
Fracton phases feature elementary excitations with fractionalized mobility and are exciting interest from multiple areas of theoretical physics. However, the most exotic 'type-II'…
Complex charge density waves at Van Hove singularity on hexagonal lattices: Haldane-model phase diagram and potential realization in kagome metals
Yu-Ping Lin, Rahul M. Nandkishore
We investigate how the real and imaginary charge density waves interplay at the Van Hove singularity on the hexagonal lattices. A phenomenological analysis indicates the formation…
Symmetry protected self correcting quantum memory in three space dimensions
Charles Stahl, Rahul Nandkishore
Whether self correcting quantum memories can exist at non-zero temperature in a physically reasonable setting remains a great open problem. It has recently been argued [1] that sym…
