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
The paper proposes two nonlocal order parameters based on symmetry‑twisted multi‑entropies that can detect and distinguish all 2D bosonic symmetry‑protected topological phases with…
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…
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…
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…
