Quadrupolar magnetic excitations in an isotropic spin-1 antiferromagnet
A. Nag, A. Nocera, S. Agrestini +5
The microscopic origins of emergent behaviours in condensed matter systems are encoded in their excitations. In ordinary magnetic materials, single spin-flips give rise to collecti…
Particle-hole asymmetry in the dynamical spin and charge structure factors of the corner-shared one-dimensional cuprates
Shaozhi Li, Alberto Nocera, Umesh Kumar +1
The collective spin and charge excitations of doped cuprates and their relationship to superconductivity are not yet fully understood, particularly in the case of the charge excita…
Quantum Phase Transition of Many Interacting Spins Coupled to a Bosonic Bath: static and dynamical properties
G. De Filippis, A. de Candia, A. S. Mishchenko +7
By using worldline and diagrammatic quantum Monte Carlo techniques, matrix product state and a variational approach à la Feynman, we investigate the equilibrium properties and rela…
