Emergent energy scales in magnonic systems with relative motion
Daigo Oue
Relative motion between interacting systems can generate emergent energy scales that are absent in isolated systems. While uniform motion can be eliminated by a Galilean transforma…
Fluctuation-induced Hall-like lateral forces in a chiral-gain environment
Daigo Oue, Mário G. Silveirinha
Here, we demonstrate that vacuum fluctuations can induce lateral forces on a small particle positioned near a translation-invariant uniform non-Hermitian substrate with chiral gain…
Parametric instability in a magnomechanical system
Takahiro Uto, Daigo Oue
We study parametric instability in a magnomechanical system, specifically examining magnon tunneling between moving ferromagnetic insulators. Our analysis reveals that quantum fluc…
Optimising motion-induced spin transfer
Daigo Oue, Matsuo Mamoru
In this paper, the spin transfer between two ferromagnetic insulators is studied. There is a narrow gap between the ferromagnetic insulators so that they are weakly interacting wit…
Quantum fluctuation in rotation velocity of a levitated magnetic particle
T. Sato, Daigo Oue, M. Matsuo +1
We consider a ferromagnetic particle levitated in air under microwave irradiation and theoretically study the noise in its rigid-body rotation induced by the gyromagnetic effect. T…
Valley hydrodynamics in gapped graphene
Ryotaro Sano, Daigo Oue, Mamoru Matsuo
Recent experiments have revealed that novel nonequilibrium states consistent with the hydrodynamic description of electrons are realized in ultrapure graphene, which hosts the vall…
