Non-linear rheology of layered systems - a phase model approach

Hajime Yoshino, Hiroshi Matsukawa, Satoshi Yukawa +1

We study non-linear rheology of a simple theoretical model developed to mimic layered systems such as lamellar structures under shear. In the present work we study a 2-dimensional…

Deconfinement of Vortices with Continuously Variable Fractions of the Unit Flux Quanta in Two-Gap Superconductors

Jun Goryo, Singo Soma, Hiroshi Matsukawa

We propose a new stage of confiment-decofinment transition, which can be observed in laboratory. In two-gap superconductors (SCs), two kinds of vortex exist and each of them carrie…

Possibility of the Solid-Fluid Transition in Moving Periodic Systems

Tomoaki Nogawa, Hajime Yoshino, Hiroshi Matsukawa

The steady sliding state of periodic structures such as charge density waves and flux line lattices is numerically studied based on two and three dimensional driven random field XY…

Flux flow resistivity in the two-gap superconductivity

Jun Goryo, Hiroshi Matsukawa

We investigate the flux flow state in a two-gap superconductor in which two s-wave gaps with different amplitudes exist on two separate Fermi surfaces. The flux flow resistivity is…

Flux flow resistivity in the system with multiple superconducting gaps

Jun Goryo, Hiroshi Matsukawa

We calculate the flux flow resistivity in a superconductor with multiple s-wave superconducting gaps. Our result agrees well with anomalous field dependence of the resistivity rece…

Atomic scale friction between clean graphite surfaces

Katsuyoshi Matsushita, Hiroshi Matsukawa, Naruo Sasaki

We investigate atomic scale friction between clean graphite surfaces by using molecular dynamics. The simulation reproduces atomic scale stick-slip motion and low frictional coeffi…
