Pseudo-Hermitian Magnon Dynamics
Jamal Berakdar, Xi-guang Wang
A defining quantity of a physical system is its energy which is represented by the Hamiltonian. In closed quantum mechanical or/and coherent wave-based systems the Hamiltonian is i…

PT-Symmetric Magnon Lasing and Anti-Lasing
Xi-guang Wang, Tian-xiang Lu, Guang-hua Guo +2
A mechanism for electrically tunable PT-symmetric magnonic lasing and anti-lasing is proposed along with a device consisting of a current-biased region in a magnetically ordered pl…

Electrically Tunable Magnonic Bound States in the Continuum
Xi-guang Wang, Guang-hua Guo, Jamal Berakdar +1
Low energy excitations of a magnetically ordered system are spin waves with magnon being their excitation quanta. Magnons are demonstrated to be useful for data processing and comm…
