Quantum Brownian transport in a correlated Gaussian force
Yun Jeong Kang, Seungsik Min, Sung Kyu Seo +1
We study a classical system-bath model in which a system particle is linearly coupled to a bath of harmonic oscillators. In a system subject to white and correlated Gaussian noises…
Fractional motions of an active particle on the quantum vortex
Yun Jeong Kang, Sung Kyu Seo, Kyungsik Kim
We analytically investigate the diffusive motion inferred from experimental observations of active particles driven by quantum vortices on the surface of superfluid helium. We firs…
Quantum diffusion for a quantum particle with a correlated Gaussian noise
Yun Jeong Kang, Sung Kyu Seo, Kyungsik Kim
We investigate the diffusive behavior of a quantum particle driven by a correlated Gaussian noise. We derive the analytical solution of the joint probability density function and o…
Analytical solutions for a charged particle with white, thermal, and active noises in the presence of a uniform magnetic field
Y. J. Kang, S. K. So, Kyungsik Kim
We study the two-dimensional equations of motion for a charged particle subjected to white, thermal, and active noises in uniform a magnetic field. By deriving the corresponding Fo…
On dynamical behaviors in the fractional generalized Langevin equation
Yun Jeong Kang, Kyungsik Kim
The focus of our study in this paper is on the active dynamics and a fractional generalized Langevin equation with a memory kernel K(t). The Fokker-Planck equation is obtained by d…
