Quantifying and controlling entanglement in the quantum magnet CsCoCl
Pontus Laurell, Allen Scheie, Chiron J. Mukherjee +7
The lack of methods to experimentally detect and quantify entanglement in quantum matter impedes our ability to identify materials hosting highly entangled phases, such as quantum…
Exact resummation of the Holstein-Primakoff expansion and differential equation approach to operator square-roots
Michael Vogl, Pontus Laurell, Hao Zhang +2
Operator square-roots are ubiquitous in theoretical physics. They appear, for example, in the Holstein-Primakoff representation of spin operators and in the Klein-Gordon equation.…
Van Hove singularity in the magnon spectrum of the antiferromagnetic quantum honeycomb lattice
G. Sala, M. B. Stone, Binod K. Rai +12
The magnetic excitation spectrum of the quantum magnet YbCl is studied with inelastic neutron scattering. The spectrum exhibits an unusually sharp feature within a broad contin…
