Marginally localized edges of time-reversal symmetric topological superconductors
Yang-Zhi Chou, Rahul M. Nandkishore
We demonstrate that the one-dimensional helical Majorana edges of two-dimensional time-reversal symmetric topological superconductors (class DIII) can become gapless and insulating…
Tunable-spin-model generation with spin-orbit-coupled fermions in optical lattices
Mikhail Mamaev, Itamar Kimchi, Rahul M. Nandkishore +1
We study the dynamical behaviour of ultracold fermionic atoms loaded into an optical lattice under the presence of an effective magnetic flux, induced by spin-orbit coupled laser d…
Spectroscopic fingerprints of gapped quantum spin liquids, both conventional and fractonic
Rahul M. Nandkishore, Wonjune Choi, Yong Baek Kim
We explain how gapped quantum spin liquids, both conventional and 'fractonic', may be unambiguously diagnosed experimentally using the technique of multidimensional coherent spectr…
Multipole conservation laws and subdiffusion in any dimension
Jason Iaconis, Andrew Lucas, Rahul Nandkishore
Subdiffusion is a generic feature of chaotic many-body dynamics with multipole conservation laws and subsystem symmetries. We numerically study this subdiffusive dynamics, using qu…
Parquet renormalization group analysis of weak-coupling instabilities with multiple high-order Van Hove points inside the Brillouin zone
Yu-Ping Lin, Rahul M. Nandkishore
We analyze the weak-coupling instabilities that may arise when multiple high-order Van Hove points are present inside the Brillouin zone. The model we consider is inspired by twist…
Hydrodynamics in lattice models with continuous non-Abelian symmetries
Paolo Glorioso, Luca V. Delacrétaz, Xiao Chen +2
We develop a systematic effective field theory of hydrodynamics for many-body systems on the lattice with global continuous non-Abelian symmetries. Models with continuous non-Abeli…
