Gauge invariance of many-body Schrödinger equation with explicit Coulomb potential
Kikuo Cho
A simple argument is presented which, based on the minimal coupling Lagrangian for a many-body system, keeps the gauge invariance of the many-body Schrödinger equation with explici…
Dispersion Relation in Chiral Media: Credibility of Drude-Born-Fedorov equations
Kikuo Cho
Disperion relation of EM field in a chiral medium is discussed from the viewpoint of constitutive equations to be used as a partner of Maxwell equations. The popular form of Drude-…
Model-independent derivation of macroscopic Maxwell equations from microscopic basis: Beyond the "εand μ" description
Kikuo Cho
Pointing out the incompleteness of conventional macroscopic Maxwell equations (M-eqs.), we propose a new form derived from the long wavelength approximation (LWA) of microscopic no…
Bragg diffraction of microcavity polaritons by a surface acoustic wave
K. Cho, K. Okumoto, N. I. Nikolaev +1
Bragg scattering of polaritons by a coherent acoustic wave is mediated and strongly enhanced by the relevant exciton states resonant with the acoustic and optic fields simultaneous…
