Storage and retrieval of microwave fields at the single-photon level in a spin ensemble
C. Grezes, B. Julsgaard, Y. Kubo +13
We report the storage of microwave pulses at the single-photon level in a spin-ensemble memory consisting of NV centers in a diamond crystal coupled to a superconducting…
Modification of Angular Velocity by Inhomogeneous MRI Growth in Protoplanetary Disks
M. T. Kato, K. Nakamura, R. Tandokoro +2
We have investigated evolution of magneto-rotational instability (MRI) in protoplanetary disks that have radially non-uniform magnetic field such that stable and unstable regions c…
Diffusion in the Markovian limit of the spatio-temporal colored noise
Takaaki Monnai, Ayumu Sugita, Katsuhiro Nakamura
We explore the diffusion process in the non-Markovian spatio-temporal noise.%the escape rate problem in the non-Markovian spatio-temporal random noise. There is a non-trivial short…
Generalised Ornstein-Uhlenbeck processes
V. Bezuglyy, B. Mehlig, M. Wilkinson +2
We solve a physically significant extension of a classic problem in the theory of diffusion, namely the Ornstein-Uhlenbeck process [G. E. Ornstein and L. S. Uhlenbeck, Phys. Rev. 3…
Equatorial and related non-equilibrium states in magnetization dynamics of ferromagnets: Generalization of Suhl's spin-wave instabilities
C. Kosaka, K. Nakamura, S. Murugesh +1
We investigate the nonlinear dynamics underlying the evolution of a 2-D nanoscale ferromagnetic film with uniaxial anisotropy in the presence of perpendicular pumping. Considering…
Two interacting hard disks within a circular cavity: towards a quantal equation of states
T. Kato, N. Nakazono, K. Nakamura
We investigate a circular cavity billiard within which a pair of identical hard disks of smaller but finite size is confined. Each disk shows a free motion except when bouncing ela…
