Topological Defects and Morphology of Graphitic Carbon Materials: An Approach Based on Differential Geometry
Masahiko Hayashi
It has been known that pentagons and heptagons in hexagonal graphitic network give rise to a certain amount of curvature in the three dimensional structure of graphitic carbon mate…
Superconductivity Induced by the Proximity Effect of Singlet Resonating Valence Bond Order in High- Superconductors
M. Hayashi, H. Ebisawa
Effects of inhomogeneous doping on the high- cuprate superconductors are studied within the framework of the t-J model. Especially, the boundary between two non-superconductin…
On the Ginzburg-Landau Free Energy of Charge Density Waves with a Three-Dimensional Order
Masahiko Hayashi, Hideo Yoshioka
The effective free energy of a charge density wave (CDW) with a three-dimensional order is derived from a microscopic model (Frölich model) based on the path integral method. Elect…
Spectral Flow and the Dynamics of Dislocations in Charge Density Waves
Masahiko Hayashi
The spectral flow in the cores of moving dislocations is found to play an important role in the dynamics and transport of charge density wave (CDW) by significantly modifying the h…
