Perfect elliptic dichroism: Probing the metric of anisotropic quantum Hall droplets
Bruno Mera, Alberto Nardin, Anaïs Defossez +3
Understanding the geometry of quantum Hall systems is a central challenge in modern condensed matter physics. We introduce a framework for probing the geometric structure of quantu…
Hall viscosity from metric-sensitive dichroic probes
Alberto Nardin, Bruno Mera, Anaïs Defossez +3
Hall viscosity characterizes the geometric response of a quantum Hall droplet to deformations of the underlying metric, yet it has remained difficult to measure directly. We propos…
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…
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…
A local quantized marker for topological magnons from circular dichroism
Baptiste Bermond, Anaïs Defossez, Gregor Jotzu +1
The low-energy excitations of a spin system can display Bloch bands with non-trivial topological properties. While topological magnons can be identified through the detection of ch…
Giant quantum oscillations in thermal transport in low-density metals via electron absorption of phonons
B. Bermond, R. Wawrzynczak, S. Zherlitsyn +14
Oscillations of conductance observed in strong magnetic fields are a striking manifestation of the quantum dynamics of charge carriers in solids. The large charge carrier density i…
Anomalous Casimir effect in an expanding ring
Baptiste Bermond, Adolfo G. Grushin, David Carpentier
The Casimir effect is a macroscopic evidence of the quantum nature of the vacuum. On a ring, it leads to a finite size correction to the vacuum energy. In this work, we show that t…
Anomalous Luttinger equivalence between temperature and curved spacetime: From black hole's atmosphere to thermal quenches
Baptiste Bermond, Maxim Chernodub, Adolfo G. Grushin +1
Building on the idea of Tolman and Ehrenfest that heat has weight, Luttinger established a deep connection between gravitational fields and thermal transport. However, this relatio…
