Dynamical Mass Growing of Fermion with Bare Mass in Two Dimensions
Toyoki Matsuyama
We study dynamical mass generation of a fermion with and without a bare mass by coupling with a massive vector field in two-dimensional space-time. To estimate a non-perturbative e…
The Nakano-Nishijima-Gell-Mann Formula From Discrete Galois Fields
Keiji Nakatsugawa, Motoo Ohaga, Toshiyuki Fujii +2
The well known Nakano-Nishijima-Gell-Mann (NNG) formula relates certain quantum numbers of elementary particles to their charge number. This equation, which phenomenologically intr…
Emergence of the Chern structure using SrRuO nanofilms
Hiroyoshi Nobukane, Toyoki Matsuyama, Satoshi Tanda
We discovered a fractional Chern structure in chiral superconducting SrRuO nanofilms by employing electric transport. By using SrRuO single crystals with nanoscale…
Effects of Chern-Simons Corrections on Conserved Quantities of Relativistic Fluid
Kohkichi Konno, Toyoki Matsuyama, Satoshi Tanda
We consider relativistic fluid flow under Chern-Simons modified Maxwell theory and under Chern-Simons modified gravity theory. We take account of the effects of Chern-Simons correc…
Discovery of parity-violating Majorana fermions in a chiral superconductor Sr2RuO4
Hiroyoshi Nobukane, Akiyuki Tokuno, Toyoki Matsuyama +1
We found parity-violating Majorana fermions in a chiral superconductor Sr2RuO4. The current-voltage curves show an anomalous behavior: The induced voltage is an even function of th…
Rotating black hole in extended Chern-Simons modified gravity
Kohkichi Konno, Toyoki Matsuyama, Satoshi Tanda
We investigate a slowly rotating black hole in four-dimensional extended Chern-Simons modified gravity. We obtain an approximate solution that reduces to the Kerr solution when a c…
