Self-dual Higgs transitions: Toric code and beyond
Wenjie Ji, Ryan A. Lanzetta, Zheng Zhou +1
The toric code, when deformed in a way that preserves the self-duality symmetry exchanging the electric and magnetic excitations, admits a transition to a topologica…
The Free-Scalar and Wilson-Fisher Conformal Field Theories on the Fuzzy Sphere
Wenhan Guo, Zheng Zhou, Tzu-Chieh Wei +1
The fuzzy-sphere regularization is an emerging numerical and theoretical technique for studying conformal field theories (CFTs). In this paper, we apply it to the vector mod…
Universal Decay of Mutual Information and Conditional Mutual Information in Gapped Pure- and Mixed-State Quantum Matter
Jinmin Yi, Kangle Li, Chuan Liu +2
For spin and fermionic systems in any spatial dimension, we establish that the superpolynomial decay behavior of mutual information and conditional mutual information is a universa…
Finite-Size Spectral Signatures of Order by Quantum Disorder: A Perspective from Anderson's Tower of States
Subhankar Khatua, Griffin C. Howson, Michel J. P. Gingras +1
In frustrated magnetic systems with a subextensive number of classical ground states, quantum zero-point fluctuations can select a unique long-range ordered state, a celebrated phe…
Anharmonic Collective Oscillations in Isotropic Spin Systems and their Spectroscopic Signatures
Anna Fancelli, Matías G. Gonzalez, Subhankar Khatua +4
Spin waves are the fundamental excitations in magnetically ordered spin systems and are ubiquitously observed in magnetic materials. However, the standard understanding of spin wav…
Autoregressive neural quantum states of Fermi Hubbard models
Eduardo Ibarra-García-Padilla, Hannah Lange, Roger G Melko +4
Neural quantum states (NQS) have emerged as a powerful ansatz for variational quantum Monte Carlo studies of strongly-correlated systems. Here, we apply recurrent neural networks (…
Synthesis and characterization of the novel breathing pyrochlore compound Ba3Tm2Zn5O11
Lalit Yadav, Rabindranath Bag, Ramesh Dhakal +10
In this study, a novel material from the rare-earth based breathing pyrochlore family, Ba3Tm2Zn5O11, was successfully synthesized. Powder x-ray diffraction and high-resolution powd…
Entanglement area law and Lieb-Schultz-Mattis theorem in long-range interacting systems, and symmetry-enforced long-range entanglement
Ruizhi Liu, Jinmin Yi, Shiyu Zhou +1
We establish multiple interrelated, fundamental results in quantum many-body systems that can have long-range interactions. For a sufficiently long quantum spin chain, we first sho…
Ground state properties of the Heisenberg-compass model on the square lattice
Subhankar Khatua, Griffin C. Howson, Michel J. P. Gingras +1
Compass models provide insights into the properties of Mott-insulating materials that host bond-dependent anisotropic interactions between their pseudospin degrees of freedom. In t…
Order-by-disorder without quantum zero-point fluctuations in the pyrochlore Heisenberg ferromagnet with Dzyaloshinskii-Moriya interactions
Alexander Hickey, Daniel Lozano-Gómez, Michel J. P. Gingras
Order-by-disorder, whereby fluctuations lift an accidental classical ground state degeneracy to stabilize a subset of ordered states, is a recurrent and prominent theme in the fiel…
Mixed-state quantum anomaly and multipartite entanglement
Leonardo A. Lessa, Meng Cheng, Chong Wang
Quantum entanglement measures of many-body states have been increasingly useful to characterize phases of matter. Here we explore a surprising connection between mixed state entang…
Emergent magnetic order in the antiferromagnetic Kitaev model with a [111] field
Will Holdhusen, Daniel Huerga, Gerardo Ortiz
The Kitaev spin liquid, stabilized as the ground state of the Kitaev honeycomb model, is a paradigmatic example of a topological quantum spin liquid. The fate of the…
Neural network approach to quasiparticle dispersions in doped antiferromagnets
Hannah Lange, Fabian Döschl, Juan Carrasquilla +1
Numerically simulating spinful, fermionic systems is of great interest from the perspective of condensed matter physics. However, the exponential growth of the Hilbert space dimens…
2-Form U(1) Spin Liquids: Classical Model and Quantum Aspects
Kristian Tyn Kai Chung, Michel J. P. Gingras
We introduce a novel geometrically frustrated classical Ising model, dubbed the "spin vorticity model", whose ground state manifold is a novel classical spin liquid, a "2-form Coul…
Competing Gauge Fields and Entropically-Driven Spin Liquid to Spin Liquid Transition in non-Kramers Pyrochlores
Daniel Lozano-Gómez, Vincent Noculak, Jaan Oitmaa +4
Gauge theories are powerful tools in theoretical physics, allowing complex phenomena to be reduced to simple principles, and are used in both high-energy and condensed matter physi…
Resonant X-Ray Scattering Investigations of Charge Density Wave and Nematic Orders in Cuprate Superconductors
David G Hawthorn
In the cuprate superconductors, superconductivity often co-exists with other types of order, including charge density wave and nematic orders. Over the past decade, resonant x-ray…
Fusion mechanism for quasiparticles and topological quantum order in the lowest Landau level
Arkadiusz Bochniak, Gerardo Ortiz
Starting from Halperin multilayer systems we develop a hierarchical scheme that generates, bosonic and fermionic, single-layer quantum Hall states (or vacua) of arbitrary filling f…

Zheng Zhou, Liangdong Hu, W. Zhu +1
The deconfined quantum critical point (DQCP) is an example of phase transitions beyond the Landau symmetry breaking paradigm that attracts wide interest. However, its nature has no…
Tuning charge density wave order and structure via uniaxial stress in a stripe-ordered cuprate superconductor
Naman K. Gupta, Ronny Sutarto, Rantong Gong +4
Unidirectional spin and charge density wave order in the cuprates is known to compete with superconductivity. In the stripe order (La,M)CuO family of cuprates, spin and cha…
