Dichroism from Chiral Thermoelectric Probes: Generalized Sum Rules for Orbital and Heat Magnetizations

Baptiste Bermond, Lucila Peralta Gavensky, Anaïs Defossez +1 more·Nov 26, 2025

We introduce a unified framework that relates orbital and heat magnetizations to experimentally accessible excitation spectra, through thermoelectric probes and generalized sum rules. By analyzing zero-temperature transport coefficients and applying ...

Quantum Optimality in the Odd-Cycle game: the topological odd-blocker, marked connected components of the giant, consistency of pearls, vanishing homotopy

Pete Rigas·Nov 26, 2025

We characterize optimality of Quantum strategies for the Odd-Cycle game. Separate from other game-theoretic settings, parallel repetition for the Odd-Cycle game is related to the foam problem, which can be formulated through a minimization of the sur...

Magnetic Control of the Non-Hermitian Skin Effect in Two-Dimensional Lattices

Stefano Longhi·Nov 25, 2025

The non-Hermitian skin effect (NHSE) -- the anomalous boundary accumulation of an extensive number of bulk modes -- has emerged as a hallmark of non-Hermitian physics, with broad implications for transport, sensing, and topological classification. A ...

Generation of Ultrahigh Anomalous Hall Conductivities via Optimally Prepared Topological Floquet States

Andrew Cupo, Hai-Ping Cheng, Chandrasekhar Ramanathan +1 more·Nov 25, 2025

Ultrafast quantum matter experiments have validated predictions from Floquet theory - notably, the dynamical modification of the electronic band structure and the light-induced anomalous Hall effect, via monotonic modulation of the driving amplitude....

Exciton collective modes in a bilayer of axion insulator $\text{MnBi}_2 \text{Te}_4$

Olivia Liebman, Jonathan B. Curtis, Emily Been +1 more·Nov 25, 2025

We investigate the emergence of an exciton condensate and associated collective modes in a bilayer configuration of $\text{MnBi}_2\text{Te}_4$, an antiferromagnetic topological insulator and van der Waals material, recognized for hosting axion physic...

Generalized Landau Paradigm for quantum phases and phase transitions

Xie Chen·Nov 24, 2025

The Landau paradigm is a central dogma for understanding phase and phase transitions in condensed matter systems, yet for decades it has been known that a variety of quantum phases exist beyond the framework. Is there a more general framework that pr...

Holographic duality between bulk topological order and boundary mixed-state order

Tsung-Cheng Lu, Yu-Jie Liu, Sarang Gopalakrishnan +1 more·Nov 24, 2025

We introduce a holographic framework for analyzing the steady states of repeated quantum channels with strong symmetries. Using channel-state duality, we show that the steady state of a $d$-dimensional quantum channel is holographically mapped to the...

Topological BF Theory construction of twisted dihedral quantum double phases from spontaneous symmetry breaking

Zhi-Qiang Gao, Chunxiao Liu, Joel E. Moore·Nov 24, 2025

Nonabelian topological orders host exotic anyons central to quantum computing, yet established realizations rely on case-by-case constructions that are often conceptually involved. In this work, we present a systematic construction of nonabelian dihe...

Web of Non-invertible Dualities for (2+1) Dimensional Models with Subsystem Symmetries

Avijit Maity, Vikram Tripathi, Andriy H. Nevidomskyy·Nov 24, 2025

We extend non-invertible duality concepts from one-dimensional systems to two spatial dimensions by constructing a web of non-invertible dualities for lattice models with subsystem symmetries. For the $\mathbb{Z}_2 \times \mathbb{Z}_2$ subsystem symm...

Non-Hermitian topology in a single driven-dissipative Kerr-Cat qubit

Pei-Rong Han, Huiye Qiu, Hao-Long Zhang +3 more·Nov 23, 2025

The intriguing physical phenomena associated with exceptional points have established non-Hermitian physics as a frontier of modern research. Recent investigations have extended non-Hermitian physics into the fully quantum domain. However, existing s...

Unified Bulk-Entanglement Correspondence in Non-Hermitian Systems

Xudong Zhang, Zhaoyu Sun, Bin Guo·Nov 22, 2025

The non-Hermitian skin effect (NHSE) fundamentally invalidates the conventional bulk-boundary correspondence (BBC), leading topological diagnostics into a crisis. While the non-Bloch polarization $P_β$ defined on the generalized Brillouin zone restor...

Fractional Chern insulator edges: crystalline effects and optical measurements

Yan-Qi Wang, Johannes Motruk, Andrey Grankin +1 more·Nov 21, 2025

Edge states of chiral topologically ordered phases are commonly described by chiral Luttinger liquids, effective theories that are exact only in the hydrodynamic limit. Motivated by recent bulk observations of fractional Chern insulators (FCIs) in tw...

Measuring Anyonic Exchange Phases Using Two-Dimensional Coherent Spectroscopy

Nico Kirchner, Wonjune Choi, Frank Pollmann·Nov 21, 2025

Identifying experimental signatures of anyons, which exhibit fractional exchange statistics, remains a central challenge in the study of two-dimensional topologically ordered systems. Previous theoretical work has shown that the threshold behavior in...
