Three-body scattering problem and two-electron tunneling in molecular wires

A. S. Alexandrov, A. M. Bratkovsky, P. E. Kornilovitch

We solve the Lippmann-Schwinger equation describing elastic scattering of preformed pairs (e.g. bipolarons) off a short-range scattering center and find the two-particle transmissi…

Charge dynamics and metal-insulator transition in Si $_{1 - x}$ Gd $_{x}$ and Si $_{1 - x}$ Y $_{x}$ alloys

D. N. Basov, A. M. Bratkovsky, P. F. Henning +5

Carrier dynamics in amorphous a-Si $_{1 - x}$ RE $_{x}$ (RE=Gd, Y) films has been studied in the doping regime close to the metal-insulator transition by means of infrared spectroscopy.…

Theory of optical conductivity in doped manganites

A. S. Alexandrov, A. M. Bratkovsky

The frequency and temperature dependence of the optical conductivity of ferromagnetic manganites is explained within the framework of the bipolaron theory. As these materials are c…
