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…
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…
