Friedel Sum Rule as a Trace Formula
Mahito Kohmoto, Tohru Koma
We examine the Friedel sum rule which states that the "excess charge" due to a single impurity potential in a metal is equal to a sum of phase shifts for scatterings of electrons b…
Pump process of the rotatory molecular motor and its energy efficiency
Hiroshi Miki, Masatoshi Sato, Mahito Kohmoto
The pump process of the ratchet model inspired by the rotatory motor of ATP synthase is investigated. In this model there are two kinds of characteristic time. One is dynamic…
Propagation of Light in Cantor Media
Masanori Yamanaka, Mahito Kohmoto
We numerically find that transmission coefficients have a rich structure as a function of wavelength in Cantor media. Complete transmission and complete reflection are observed. We…
Unconventional odd-parity superconductivity in the ladder compounds
Mahito Kohmoto, Masatoshi Sato
Superconductive properties of the two-leg ladder compounds are studied theoretically. The antiferromagnetic fluctuations are considered because of the good nesting of the Fermi sur…
High temperature superconductivity from the two-dimensional semiconductors without magnetism
Mahito Kohmoto, Iksoo Chang, Jacques Friedel
We examine the possibility of high temperature superconductivity from two-dimensional semiconductor without antiferromagnetic fluctuations. The weak coupling BCS theory is applied,…
Anisotropy and magnetism of high temperature oxides superconductors
J. Friedel, M. Kohmoto
Phonon or electron mediated weak BCS attraction is enough to have high critical temperature if a van Hove anomaly is at work. This could apply to electron doped compounds and also…
