Luttinger's Theorem Violation and Green's Function Topological Invariants in a Fractional Chern Insulator
Anton A. Markov, Andrey M. Nikishin, Nigel R. Cooper +2
Luttinger's theorem constrains the particle density of interacting fermions through global properties of the single-particle Green's function, and its violation signals a breakdown…
Dichroism from Chiral Thermoelectric Probes: Generalized Sum Rules for Orbital and Heat Magnetizations
Baptiste Bermond, Lucila Peralta Gavensky, Anaïs Defossez +1
We introduce a unified framework that relates orbital and heat magnetizations to experimentally accessible excitation spectra, through thermoelectric probes and generalized sum rul…
Controlled Buildup of Half-Quantized Thermal Conductance in an Engineered Chiral Spin Liquid Platform
Bo-Ye Sun, Baptiste Bermond, Lucila Peralta Gavensky +3
We study thermal transport along the edge of a small chiral-spin-liquid device coupled to two Ising-chain reservoirs, a platform suitable for quantum-engineered systems. Adiabatica…
Dynamic Realization of Majorana Zero Modes in a Particle-Conserving Ladder
Anais Defossez, Laurens Vanderstraeten, Lucila Peralta Gavensky +1
We present a scheme to realize a topological superconducting system supporting Majorana zero modes, within a number-conserving framework suitable for optical-lattice experiments. O…
