The landscape of symmetry enhancement in tight-binding models
A. K. Dagnino, A. Corticelli, M. Gohlke +3
Band structures are ubiquitous in condensed matter physics and their symmetries constrain possible degeneracies, topology and response functions across a broad range of different s…
Dissipation-induced long-range order in the one-dimensional Bose-Hubbard model
Afonso L. S. Ribeiro, Paul McClarty, Pedro Ribeiro +1
Understanding the stability of strongly correlated phases of matter when coupled to environmental degrees of freedom is crucial for identifying the conditions under which these sta…
The Crystallographic Spin Point Groups and their Representations
Hana Schiff, Alberto Corticelli, Afonso Guerreiro +2
The spin point groups are finite groups whose elements act on both real space and spin space. Among these groups are the magnetic point groups in the case where the real and spin s…
Dirac magnons, nodal lines, and nodal plane in elemental gadolinium
Allen Scheie, Pontus Laurell, Paul A. McClarty +4
We investigate the magnetic excitations of elemental gadolinium (Gd) using inelastic neutron scattering, showing that Gd is a Dirac magnon material with nodal lines at and noda…
Spin exchange Hamiltonian and topological degeneracies in elemental gadolinium
Allen Scheie, Pontus Laurell, Paul A. McClarty +4
We present a comprehensive study of the magnetic exchange Hamiltonian of elemental Gadolinium. We use neutron scattering to measure the magnon spectrum over the entire Brillouin zo…
Topological Magnons: A Review
Paul McClarty
At sufficiently low temperatures magnetic materials often enter a correlated phase hosting collective, coherent magnetic excitations such as magnons or triplons. Drawing on the eno…
