Ohm's law, Joule heat, and Planckian dissipation
Hiroyasu Koizumi
Electric current generation and its dissipation are important physical processes. It ranges from the one follows the Ohm's law to superconductivity. Recently, it has been shown tha…
Constrained Hamiltonian dynamics for electrons in magnetic field and additional forces besides the Lorentz force acting on electrons
Hiroyasu Koizumi
We consider the forces acting on electrons in magnetic field including the constraints and a condition arising from quantum mechanics. The force is calculated as the electron mass,…
Calculations of magnetic field produced by spin-vortex-induced loop currents in BiSrCaCuO thin films using the particle-number conserving Bogoliubov-de Gennes formalism
Hiroyasu Koizumi, Haruki Nakayama, Hayato Taya
A theory for cuprate superconductivity predicts the existence of nano-sized loop currents called, `` spin-vortex-induced loop currents (SVILCs)''. We calculate magnetic fields prod…
Gauge invariant quantization for circuits including Josephson junctions
Hiroyasu Koizumi
Recently, a new theory of superconductivity has been put forward that attributes the origin of superconductivity to the appearance of a non-trivial Berry connection from many-elect…
