Cryogenic spin Seebeck effect
Mehrdad Elyasi, Gerrit E. W. Bauer
We present a theory of the non-linearities of the spin Seebeck effect (SSE) in a ferromagnetic nanowire at cryogenic temperatures. We adopt a microscopic quantum noise model based…
Resources of nonlinear cavity magnonics for quantum information
Mehrdad Elyasi, Yaroslav M. Blanter, Gerrit E. W. Bauer
We theoretically explore nonlinearities of ferromagnets in microwave cavities in the classical and quantum regimes, and assess the resources for quantum information, i.e. fluctuati…
Topologically nontrivial magnonic solitons
Mehrdad Elyasi, Koji Sato, Gerrit E. W. Bauer
The intrinsic non-linearities of the spin dynamics in condensed matter systems give rise to a rich phenomenology that can be strongly affected by topology. Here we study formation…
Cloaking the magnons
Mehrdad Elyasi, Charanjit S. Bhatia, Cheng-Wei Qiu +1
We propose two approaches to cloak the spin waves (magnons) by investigating magnetization dynamics. One approach is based on a spatially inhomogeneous anisotropic magnetic moment…
Magnetization reversal using excitation of collective modes in nanodot matrices
Mehrdad Elyasi, Charanjit S. Bhatia, Hyunsoo Yang
The large arrays of magnetic dots are the building blocks of magnonic crystals and the emerging bit patterned media for future recording technology. In order to fully utilize the f…
Synchronization of spin-transfer torque oscillators by spin pumping, inverse spin Hall, and spin Hall effects
Mehrdad Elyasi, Charanjit S. Bhatia, Hyunsoo Yang
We have proposed a method to synchronize multiple spin-transfer torque oscillators based on spin pumping, inverse spin Hall, and spin Hall effects. The proposed oscillator system c…
