Exact many-body wavefunction of the Kondo model with time-dependent interaction strength
Parameshwar R. Pasnoori, Emil. A. Yuzbashyan
Quantum integrability has been applied to a large variety of low dimensional Hamiltonians in Quantum Field Theory, Condensed Matter Physics, and Statistical Mechanics to obtain exa…
Instability of metals with respect to strong electron-phonon interaction
Emil A. Yuzbashyan, Boris L. Altshuler, Aniket Patra
We show that thermal equilibrium between conduction electrons and phonons becomes kinetically unstable when the renormalized electron-phonon coupling exceeds a certain threshold. W…
Quantum integrability in systems with finite number of levels
Emil A. Yuzbashyan, B. Sriram Shastry
We consider the problem of defining quantum integrability in systems with finite number of energy levels starting from commuting matrices and construct new general classes of such…
Strong Coupling Expansion for the Pairing Hamiltonian
Emil A. Yuzbashyan, Alexander A. Baytin, Boris L. Altshuler
The paper is devoted to the effects of superconducting pairing in small metallic grains. It turns out that at strong superconducting coupling and in the limit of large Thouless con…
The Origin of Degeneracies and Crossings in the 1d Hubbard Model
E. A. Yuzbashyan, B. L. Altshuler, B. S. Shastry
The paper is devoted to the connection between integrability of a finite quantum system and degeneracies of its energy levels. In particular, we analyze in detail the energy spectr…
