Abstract: We present a scheme to entangle two magnon modes in a cavity magnomechanical system. The two magnon modes are embodied by collective motions of a large number of spins in two macroscopic ferrimagnets, and couple… read more here.

Abstract: We investigate long-range coherent and dissipative coupling between two spatially separated magnets while both are coupled to a microwave cavity in the strong coupling limit. A careful examination of the system shows that the indirect… read more here.

DOI: 10.1103/physrevb.102.014409
Abstract: We discuss spin-$\frac12$ Heisenberg antiferromagnet on simple square lattice in magnetic field $H$ using recently proposed bond-operator technique. It is well known that magnetically ordered phases of quantum magnets are well described at least qualitatively… read more here.
