Symmetry-Protected Pinch Curves in Classical Spin Liquids
Takumi Fukushima, Han Yan
Classical spin liquids are correlated paramagnets in which local constraints generate extensive degeneracy and emergent gauge structures, often observable as pinch-point singularit…
Classification of Classical Spin Liquids: Typology and Resulting Landscape
Han Yan, Owen Benton, Roderich Moessner +1
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 s…
Classification of Classical Spin Liquids: Detailed Formalism and Suite of Examples
Han Yan, Owen Benton, Andriy H. Nevidomskyy +1
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 fo…
Identifying topologically critical band from pinch-point singularities in spectroscopy
Han Yan
In this paper, we investigate the relationship between pinch point singularities observed in energy- and momentum-resolved spectroscopy and topologically non-trivial gapless points…
Fractional matter coupled to the emergent gauge field in a quantum spin ice
Victor Porée, Han Yan, Félix Desrochers +7
Electronic spins can form long-range entangled phases of condensed matter named quantum spin liquids. Their existence is conceptualized in models of two- or three-dimensional frust…
Pinch points and half moons encode Berry curvature
Han Yan, Judit Romhányi, Andreas Thomasen +1
"Half moons", distinctive crescent patterns in the dynamical structure factor, have been identified in inelastic neutron scattering experiments for a wide range of frustrated magne…
