Exploring Replica Symmetry Breaking and Topological Collapse in Spin Glasses with Quantum Annealing

Kumar Ghosh·Nov 9, 2025

Replica symmetry breaking (RSB) underlies the complex organization of disordered systems, yet quantitative validation beyond $N \sim 100$ spins has remained computationally challenging. We use quantum annealing to access ground states of the Sherring...

Scaling behavior of dissipative systems with imaginary gap closing

Jinghui Pi, Xingli Li, Yangqian Yan·Nov 7, 2025

Point-gap topology, characterized by spectral winding numbers, is crucial to non-Hermitian topological phases and dramatically alters real-time dynamics. In this paper, we study the evolution of quantum particles in dissipative systems with imaginary...

Compact localized fermions and Ising anyons in a chiral spin liquid

Tim Bauer, Johannes Reuther·Nov 7, 2025

Quasiparticle hybridization remains a major challenge to realizing and controlling exotic states of matter in existing quantum simulation platforms. We report the absence of hybridization for compact localized states (CLS) emerging in the chiral spin...

Disorder-broadened topological Hall phase and anomalous Hall scaling in FeGe

Chaman Gupta, Chris Matsumura, Hongbin Yang +9 more·Nov 7, 2025

Magnetic skyrmions are topologically protected spin textures that are promising candidates for low-power spintronic memory and logic devices. Realizing skyrmion-based devices requires an understanding of how structural disorder affects their stabilit...

Symmetry-enriched topological order and quasi-fractonic behavior in $\mathbb{Z}_N$ stabilizer codes

Siyu He, Hao Song·Nov 6, 2025

We study a broad class of qudit stabilizer codes, termed $\mathbb{Z}_N$ bivariate-bicycle (BB) codes, arising either as two-dimensional realizations of modulated gauge theories or as $\mathbb{Z}_N$ generalizations of binary BB codes. Our central find...

Quantum doubles in symmetric blockade structures

Hans Peter Büchler, Tobias F. Maier, Simon Fell +1 more·Nov 6, 2025

Exactly solvable models of topologically ordered phases with non-abelian anyons typically require complicated many-body interactions which do not naturally appear in nature. This motivates the "inverse problem" of quantum many-body physics: given mic...

Emergent Dynamical Translational Symmetry Breaking as an Order Principle for Localization and Topological Transitions

Yucheng Wang·Nov 6, 2025

Localization transitions represent a fundamental class of continuous phase transitions, yet they occur without any accompanying symmetry breaking. We resolve this by introducing the concept of dynamical translational symmetry (DTS), which is defined ...

Novel Encodings of Homology, Cohomology, and Characteristic Classes

Itai Maimon·Nov 5, 2025

Topological quantum error-correcting codes (QECC) encode a variety of topological invariants in their code space. A classic structure that has not been encoded directly is that of obstruction classes of a fiber bundle, such as the Chern or Euler clas...

Clifford Hierarchy Stabilizer Codes: Transversal Non-Clifford Gates and Magic

Ryohei Kobayashi, Guanyu Zhu, Po-Shen Hsin·Nov 4, 2025

A fundamental problem in fault-tolerant quantum computation is the tradeoff between universality and dimensionality, exemplified by the the Bravyi-König bound for $n$-dimensional topological stabilizer codes. In this work, we extend topological Pauli...

Optical Vortex Transfer and Dispersion-Controlled Light Propagation in an Er YAG Three-Level Quantum System

Arefeh Vaezi, Ali Mortezapour, Seyed Hossein Asadpour·Nov 4, 2025

We theoretically investigate coherent orbital-angular-momentum (OAM) transfer and dispersion-controlled light propagation in a ladder-type Er YAG three-level system. Using the density-matrix formalism and coupled Maxwell-Bloch equations, we derive an...

Current cross-correlation spectroscopy of Majorana bound states

Michael Ridley, Eliahu Cohen, Christian Flindt +1 more·Nov 3, 2025

The clock speed of topological quantum computers based on Majorana zero mode (MZM)-supporting nanoscale devices is limited by the time taken for electrons to traverse the device. We employ the time-dependent Landauer-B{ü}ttiker transport theory for c...

Bastian Castorene, Francisco J. Peña, Patricio Vargas·Nov 3, 2025

This work examines the one-dimensional antiferromagnetic Ising model in a longitudinal magnetic field, comparing open-chain and closed-ring geometries. At the nontrivial quantum critical point (QCP) $B_{\mathrm{crit}} = B/J = 2$, we perform a microca...

Exchange operation of Majorana zero modes in topological insulator-based Josephson trijunctions

Yunxiao Zhang, Zhaozheng Lyu, Xiang Wang +19 more·Nov 2, 2025

Majorana zero modes are anyons obeying non-Abelian exchange statistics distinct from fermions or bosons. While significant progresses have been achieved in the past two decades in searching for these exotic excitations in solid-state systems, their n...
