Quantum Interference Mechanism of Cooperative Optical Phenomena in Extended Media
Valery I. Rupasov
In the quantum process of stimulated Raman scattering (SRS), a laser photon propagating in a resonance medium undergoes multifold conversions into a Stokes photon and back. The non…

On the thermodynamics of strongly correlated integrable electron systems
Valery I. Rupasov
We reexamine the Yang-Yang-Takahashi method of deriving the thermodynamic Bethe ansatz equations which describe strongly correlated electron systems of fundamental physical interes…

Potential scattering and the Kondo effect
Valery I. Rupasov
We study a generalized Kondo model in which a spin-1/2 impurity is coupled to a conduction band by both s-d exchange and potential interactions. A strong potential scattering is sh…
