Stationary and dynamical properties of a zero range process on scale-free networks
Jae Dong Noh
We study the condensation phenomenon in a zero range process on scale-free networks. We show that the stationary state property depends only on the degree distribution of underlyin…
Floquet scattering theory of negative magneto-conductance of 2DEG under microwave radiation
Kang-Hun Ahn
We develop a theory of magneto-transport properties of two-dimensional electron gas in cylindrical geometry where finite bias and microwave are locally applied. By invesitgating th…
Modeling of asymmetric giant magnetoimpedance in amorphous ribbons with a surface crystalline layer
N. A. Buznikov, C. G. Kim, C. O. Kim +1
A model describing the asymmetric giant magnetoimpedance (GMI) in field-annealed amorphous ribbons is proposed. It is assumed that the ribbon consists of an inner amorphous core an…
Off-diagonal magnetoimpedance in field-annealed Co-based amorphous ribbons
N. A. Buznikov, C. G. Kim, C. O. Kim +2
The off-diagonal magnetoimpedance in field-annealed CoFeSiB amorphous ribbons was measured in the low-frequency range using a pick-up coil wound around the sample. The asymmetric t…
Random field Ising model and community structure in complex networks
Seung-Woo Son, Hawoong Jeong, Jae Dong Noh
We propose a method to find out the community structure of a complex network. In this method the ground state problem of a ferromagnetic random field Ising model is considered on t…
A model for asymmetric giant magnetoimpedance in field-annealed amorphous ribbons
N. A. Buznikov, C. G. Kim, C. O. Kim +1
A phenomenological model for the asymmetric giant magnetoimpedance (GMI) in field-annealed amorphous ribbons is developed. The effect of a surface crystalline layer on the GMI resp…
