Relationship between the ground-state wave function of a magnet and its static structure factor
Jorge Quintanilla
We state and prove two theorems about the ground state of magnetic systems described by very general Heisenberg-type models and discuss their implications for magnetic neutron scat…
Correlated Quantum Tunnelling of Monopoles in Spin Ice
Bruno Tomasello, Claudio Castelnovo, Roderich Moessner +1
The spin ice materials HoTiO and DyTiO are by now perhaps the best-studied classical frustrated magnets. A crucial step towards the understandin…
Control of entanglement transitions in quantum spin clusters
Hannah R. Irons, Jorge Quintanilla, Toby G. Perring +2
Clustered quantum materials provide a new platform for the experimental study of many-body entanglement. Here we address a simple model of a single-molecule nano-magnet featuring N…
Single-ion anisotropy and magnetic field response in spin ice materials HoTiO and DyTiO
Bruno Tomasello, Claudio Castelnovo, Roderich Moessner +1
Motivated by its role as a central pillar of current theories of dynamics of spin ice in and out of equilibrium, we study the single-ion dynamics of the magnetic rare earth ions in…
Effect of paramagnetic fluctuations on a Fermi surface topological transition in two dimensions
Sergey Slizovskiy, Joseph J. Betouras, Sam T. Carr +1
We study the Fermi surface topological transition of the pocket-opening type in a two dimensional Fermi liquid. We find that the paramagnetic fluctuations in an interacting Fermi l…
Lifshitz transitions and crystallization of fully-polarised dipolar Fermions in an anisotropic 2D lattice
Sam T. Carr, Jorge Quintanilla, Joseph J. Betouras
We consider a two dimensional model of non-interacting chains of spinless fermions weakly coupled via a small inter-chain hopping and a repulsive inter-chain interaction. The phase…
