Superconductive "sodalite"-like clathrate calcium hydride at high pressures
Hui Wang, John S. Tse, Kaori Tanaka +2
Hydrogen-rich compounds hold promise as high-temperature superconductors under high pressures. Recent theoretical hydride structures on achieving high-pressure superconductivity ar…
Transcritical bifurcations in non-integrable Hamiltonian systems
Matthias Brack, Kaori Tanaka
We report on transcritical bifurcations of periodic orbits in non-integrable two-dimensional Hamiltonian systems. We discuss their existence criteria and some of their properties u…
Electronic structure of multiquantum giant vortex states in mesoscopic superconducting disks
K. Tanaka, I. Robel, B. Janko
We report self-consistent calculations of the microscopic electronic structure of the so-called giant vortex states. These novel multiquantum vortex states, detected by recent magn…
Occurrence of periodic Lamé functions at bifurcations in chaotic Hamiltonian systems
M. Brack, M. Mehta, K. Tanaka
We investigate cascades of isochronous pitchfork bifurcations of straight-line librating orbits in some two-dimensional Hamiltonian systems with mixed phase space. We show that the…
