Quantum Percolation Transition from Graphene to Graphane: Graph Theoretical Approach
Motohiko Ezawa
Graphane is obtained by perfectly hydrogenating graphene. There exists an intermediate material, partially hydrogenated graphene (which we call \textit{hydrographene}), interpolati…

Skyrmion Burst and Multiple Quantum Walk in Thin Ferromagnetic Films
Motohiko Ezawa
A giant Skyrmion collapses to a singular point by emitting spin waves in a thin ferromagnetic film, when external magnetic field is increased beyond the critical one. The remnant i…

Complex Structure of Triangular Graphene: Electronic, Magnetic and Electromechanical Properties
Motohiko Ezawa
We have investigated electronic and magnetic properties of graphene nanodisks (nanosize triangular graphene) as well as electromechanical properties of graphene nanojunctions. Nano…
