Topological Route to New and Unusual Coulomb Spin Liquids
(American Physical Society (APS), 2021-09-03)Coulomb spin liquids are topological magnetic states obeying an emergent Gauss law. Little distinction has been made between different kinds of Coulomb liquids. Here we show how a series of distinct Coulomb liquids can be ... -

Classification of classical spin liquids: Typology and resulting landscape
(American Physical Society, 2024-07-03)Classical spin liquids (CSL) lack long-range magnetic order and are characterized by an extensive ground-state degeneracy. We propose a classification scheme of CSLs based on the structure of the flat bands of their ... -
Hierarchy of energy scales and field-tunable order by disorder in dipolar-octupolar pyrochlores
(American Physical Society (APS), 2020-12-01)Dipolar-octupolar pyrochlore magnets in a strong external magnet field applied in the [110] direction are known to form a “chain” state, with subextensive degeneracy. Magnetic moments are correlated along one-dimensional ... -
Ising fracton spin liquid on the honeycomb lattice
(American Physical Society (APS), 2024-07-01)<jats:p>We study a classical Ising model on the honeycomb lattice with local two-body interactions and present strong evidence that at low temperature it realizes a higher-rank Coulomb liquid with fracton excitations. We ... -
Irrational Moments and Signatures of Higher-Rank Gauge Theories in Diluted Classical Spin Liquids
(American Physical Society (APS), 2024-09-03)<jats:p>Classical spin liquids (CSLs) have proved to be a fruitful setting for the emergence of exotic gauge theories. Vacancy clusters in CSLs can introduce gauge charges into the system, and the resulting behavior in ... -
Classification of classical spin liquids: Detailed formalism and suite of examples
(American Physical Society, 2024-05-10)The hallmark of highly frustrated systems is the presence of many states close in energy to the ground state. Fluctuations between these states can preclude the emergence of any form of order and lead to the appearance of ... -
Spin ice in a general applied magnetic field: Kasteleyn transition, magnetic torque, and rotational magnetocaloric effect
(American Physical Society (APS), 2022-08-30)Spin ice is a paradigmatic frustrated system famous for the emergence of magnetic monopoles and a large magnetic entropy at low temperatures. It exhibits unusual behavior in the presence of an external magnetic field as a ... -
Exactly solvable spin- 1 2 XYZ models with highly degenerate partially ordered ground states
(American Physical Society (APS), 2021-06-16)Exactly solvable models play a special role in condensed matter physics, serving as secure theoretical starting points for investigation of new phenomena. Changlani et al. [Phys. Rev. Lett. 120, 117202 (2018)] have discovered ... -
Ordered ground states of kagome magnets with generic exchange anisotropy
(American Physical Society (APS), 2021-05-21)There is a growing family of rare-earth kagome materials with dominant nearest-neighbor interactions and strong spin-orbit coupling. The low symmetry of these materials makes theoretical description complicated, with six ...
