Simplification of the local full vertex in the impurity problem in DMFT and its applications for the nonlocal correlation
Ryota Mizuno, Masayuki Ochi, Kazuhiko Kuroki
The two-particle vertex function is crucial for the diagrammatic extensions beyond DMFT for the nonlocal fluctuation. However, estimating the two-particle quantities is still a cha…
Development of an efficient impurity solver in dynamical mean field theory for multi-band systems: The iterative perturbation theory combined with the parquet equations
Ryota Mizuno, Masayuki Ochi, Kazuhiko Kuroki
Although several impurity solvers in the dynamical mean field theory (DMFT) have been proposed, especially in multi-band systems, there are practical difficulties arising from a tr…
Effects of a magnetic field on vortex states in superfluid He-B
Kenichi Kasamatsu, Ryota Mizuno, Tetsuo Ohmi +1
Superfluid He-B possesses three locally stable vortices known as a normal-core vortex (-vortex), an A-phase-core vortex (-vortex), and a double-core vortex (-vortex).…
DMFT study on the electron-hole asymmetry of the electron correlation strength in the high Tc cuprates
Ryota Mizuno, Masayuki Ochi, Kazuhiko Kuroki
Recent experiments revealed a striking asymmetry in the phase diagram of the high temperature cuprate superconductors. The correlation effect seems strong in the hole-doped systems…
