Spacetime symmetry-enriched SymTFT: from LSM anomalies to modulated symmetries and beyond
Salvatore D. Pace, Ömer M. Aksoy, Ho Tat Lam
We extend the Symmetry Topological Field Theory (SymTFT) framework beyond internal symmetries by including geometric data that encode spacetime symmetries. Concretely, we enrich th…
Deconfined classical criticality in the anisotropic quantum spin- XY model on the square lattice
Christopher Mudry, Ömer M. Aksoy, Claudio Chamon +1
The anisotropic quantum spin-1/2 XY model on a linear chain was solved by Lieb, Schultz, and Mattis in 1961 and shown to display a continuous quantum phase transition at the O(2) s…
Lieb-Schultz-Mattis type theorems for Majorana models with discrete symmetries
Ömer M. Aksoy, Apoorv Tiwari, Christopher Mudry
We prove two Lieb-Schultz-Mattis type theorems that apply to any translationally invariant and local fermionic -dimensional lattice Hamiltonian for which fermion-number conserva…
Stability against contact interactions of a topological superconductor in two-dimensional space protected by time-reversal and reflection symmetries
Ömer M. Aksoy, Jyong-Hao Chen, Shinsei Ryu +2
We study the stability of topological crystalline superconductors in the symmetry class DIIIR and in two-dimensional space when perturbed by quartic contact interactions. It is kno…
Majorana zero modes in a quantum wire platform without Rashba spin-orbit coupling
Ömer M. Aksoy, John R. Tolsma
We propose a platform for engineering helical fermions in a hybridized double-quantum-wire setup. When our setup is proximity coupled to an -wave superconductor it can become a…
