Energy-Resolved Quantum Geometry from Středa Response: Driven-Dissipative Bosonic Lattices and Disordered Systems
Anaïs Defossez, Baptiste Bermond, Lucila Peralta Gavensky +1
The Středa formula links the Hall conductivity of an insulator to the magnetic-field response of its particle density, providing a local and universal probe of the topological Cher…
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…
Probing Boundary Spins in the Su-Schrieffer-Heeger-Hubbard model
Armando A. Aligia, Alejandro M. Lobos, Lucila Peralta Gavensky +1
Studying boundary excitations provides a powerful approach to probe correlations in topological phases. We propose that localized spins near the ends of a Su-Schrieffer-Heeger-Hubb…
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…
Quantized Chern-Simons Axion Coupling in Anomalous Floquet Systems
Lucila Peralta Gavensky, Nathan Goldman, Gonzalo Usaj
Quantized bulk response functions are hallmark signatures of topological phases, but their manifestation in periodically driven (Floquet) systems is not yet fully established. Here…
The Streda Formula for Floquet Systems: Topological Invariants and Quantized Anomalies from Cesaro Summation
Lucila Peralta Gavensky, Gonzalo Usaj, Nathan Goldman
The Středa formula establishes a fundamental connection between the topological invariants characterizing the bulk of topological matter and the presence of gapless edge modes. In…
Floquet-engineered nonlinearities and controllable pair-hopping processes: From optical Kerr cavities to correlated quantum matter
Nathan Goldman, Oriana K. Diessel, Luca Barbiero +3
This work explores the possibility of creating and controlling unconventional nonlinearities by periodic driving, in a broad class of systems described by the nonlinear Schrödinger…
Floquet engineering of optical nonlinearities: a quantum many-body approach
Nathan Goldman
Subjecting a physical system to a time-periodic drive can substantially modify its properties and applications. This Floquet-engineering approach has been extensively applied to a…
Time-resolved Hall conductivity of pulse-driven topological quantum systems
Lucila Peralta Gavensky, Gonzalo Usaj, C. A. Balseiro
We address the question of how the time-resolved bulk Hall response of a two dimensional honeycomb lattice develops when driving the system with a pulsed perturbation. A simple toy…
