Tripartite entanglement in chaotic eigenstates
Junjia Zhang, Ramanjit Sohal, Shinsei Ryu
It is now well-established that classical statistical mechanics emerges from the entanglement structure of quantum chaotic systems, as quantified by the (subsystem) eigenstate ther…
Interferometric Signatures of Zero Modes in Fractional Quantum Hall-Superconductor Heterostructures
Junyi Cao, Ramanjit Sohal, Angela Kou +1
Fractional quantum Hall-superconductor (FQH-SC) heterostructures are predicted to host defect-bound parafermion zero modes (PZMs). We propose two related configurations to probe th…
Symmetry-twisted multi-entropies: Order parameters for 2D SPT phases
Ramanjit Sohal, Michael Levin, Ruben Verresen
Although symmetry-protected topological phases (SPTs) can be distinguished by their entanglement properties, it has been unclear how to extract this information directly from expec…
Obstruction to Ergodicity from Locality and Higher Symmetries on the Lattice
Ramanjit Sohal, Ruben Verresen
We argue that the presence of any exact higher-form symmetry, under mild assumptions, presents a fundamental obstruction to ergodicity under unitary dynamics in lattice syst…
The Symmetry Taco: Equivalences between Gapped, Gapless, and Mixed-State SPTs
Marvin Qi, Ramanjit Sohal, Xie Chen +2
Symmetry topological field theory (SymTFT), or topological holography, offers a unifying framework for describing quantum phases of matter and phase transitions between them. While…
Symmetry constrained field theories for chiral spin liquid to spin crystal transitions
Anjishnu Bose, Andrew Hardy, Naren Manjunath +2
We consider the spin rotationally invariant Kalmeyer-Laughlin chiral spin liquid (CSL) in systems with broken time-reversal symmetry and explore symmetry constraints on possible co…
A Noisy Approach to Intrinsically Mixed-State Topological Order
Ramanjit Sohal, Abhinav Prem
We propose a general framework for studying two-dimensional (2D) topologically ordered states subject to local correlated errors and show that the resulting mixed-state can display…
Mean field study of the topological Haldane-Hubbard model of spin- fermions
V. S. Arun, R. Sohal, C. Hickey +1
Motivated by exploring the effect of interactions on Chern insulators, and by recent experiments realizing topological bands for ultracold atoms in synthetic gauge fields, we study…
