Mapping reservoir-enhanced superconductivity to near-long-range magnetic order in the undoped one-dimensional Anderson and Kondo lattices
J. E. Ebot, Lorenzo Pizzino, Sam Mardazad +3
The undoped Kondo necklace in 1D is a paradigmatic and well understood model of a Kondo insulator. This work performs the first large-scale study of the 1D Anderson-lattice underly…
Magnetoelastic coupling at the field-induced transition in EuAlO
T. Haidamak, G. Bastien, P. Proschek +9
Magnetoelastic coupling plays a crucial role in magnetic-field-induced transitions in anisotropic ferromagnets. Ultrasonic methods are suitable for experimental investigations of t…
Field-induced states and thermodynamics of the frustrated Heisenberg antiferromagnet on a square lattice
Andreas Honecker, M. E. Zhitomirsky, Alexander Wietek +1
We investigate the ground-state and finite-temperature properties of the - Heisenberg antiferromagnet on the square lattice in the presence of an external magnetic field.…
Exponential Symmetry-Breaking Phase as a Disorder-Free Quantum Glass
Yu-Min Hu, Zhaoyu Han, Biao Lian
We study the phase diagram of a one-dimensional spin quantum breakdown model, which has an exponential symmetry with charge unit decaying as with site position .…
Hearing the light: stray-field noise from the emergent photon in quantum spin ice
Gautam K. Naik, Jonathan N. Hallén, Nishan C. Jayarama +2
Decisive experimental confirmation of the quantum spin liquid phase in quantum spin ice remains an outstanding challenge. In this work, we propose stray-field magnetometry a…
Hybrid quantum-classical matrix-product state and Lanczos methods for electron-phonon systems with strong electronic correlations: Application to disordered systems coupled to Einstein phonons
Heiko Georg Menzler, Suman Mondal, Fabian Heidrich-Meisner
We present two quantum-classical hybrid methods for simulating the time-dependence of electron-phonon systems that treat electronic correlations numerically exactly and optical-pho…
Cavity-induced coherent magnetization and polaritons in altermagnets
Mohsen Yarmohammadi, Libor Šmejkal, James K. Freericks
Altermagnets feature antiparallel spin sublattices with -, -, or -wave spin order, yielding nonrelativistic spin splitting without net magnetization. We show that embeddin…
Thermodynamics of the Heisenberg antiferromagnet on the maple-leaf lattice
Robin Schäfer, Paul L. Ebert, Noah Hassan +3
We study the Heisenberg antiferromagnet on the maple-leaf lattice using several numerical approaches, focusing on the numerical linked-cluster expansion (NLCE), which exhibits an u…
On flat bands in the -- XXZ sawtooth chain
Vadim Ohanyan, Johannes Richter, Michael Sekania +3
We consider a generalization of the XXZ model on the sawtooth spin chain with Dzyaloshinskii-Moriya interactions in which all exchange constants (symmetric, antisymmetric, and axia…
Spinon band flattening by its emergent gauge field in quantum kagome ice
Masafumi Udagawa, Roderich Moessner
Fractional excitations provide a key to identifying sought-after topological quantum spin liquid states in realistic materials. Their single-particle dynamics already presents a ch…
Entanglement spectrum of gapless topological phases: a case study with topological superconductors
Archi Banerjee, Meng Zeng
Using bulk gapless topological superconductors in both 1d and 2d as free fermion model examples, we demonstrate the power of subsystem correlation spectrum (the spectrum of correla…

We develop a low-energy field theory for electrically charged crystals. Using the tools of fracton-elasticity duality, generalized to accommodate the magnetic 1-form symmetry of el…
Ab initio spin Hamiltonians and magnetism of Ce and Yb triangular-lattice compounds
Leonid V. Pourovskii, Rafael D. Soares, Alexander Wietek
We calculate the crystal-field splitting, ground-state Kramers doublet and intersite exchange interactions within the ground-state doublet manifold using an ab initio Hubbard-I bas…

We propose a four-stroke quantum thermal machine based on the 1D anyon Hubbard model, which is capable of extracting the excess energy arising from anyon exclusion statistics at lo…
Spontaneously Broken Non-Invertible Symmetries in Transverse-Field Ising Qudit Chains
Kristian Tyn Kai Chung, Umberto Borla, Andriy H. Nevidomskyy +1
Recent developments have revealed that symmetries need not form a group, but instead can be non-invertible. Here we use analytical arguments and numerical evidence to illuminate ho…
