BRST quantization of quasi-symplectic manifolds and beyond
S. L. Lyakhovich, A. A. Sharapov
We consider a class of \textit{factorizable} Poisson brackets which includes almost all reasonable Poisson structures. A particular case of the factorizable brackets are those asso…
Experimental investigation of coherent Smith-Purcell radiation from a "flat" grating
A. Aryshev, B. Kalinin, G. Naumenko +4
Using the pre-bunched electron beam of 5-MeV linear accelerator the coherent Smith-Purcell radiation (CSPR) from a flat periodic target (made of conductive layers separated by diel…
Intertwining technique for a system of difference Schroedinger equations and new exactly solvable multichannel potentials
L. M. Nieto, B. F. Samsonov, A. A. Suzko
The intertwining operator technique is applied to difference Schroedinger equations with operator-valued coefficients. It is shown that these equations appear naturally when a disc…
New exactly solvable periodic potentials for the Dirac equation
B. F. Samsonov, A. A. Pecheritsin, E. O. Pozdeeva +1
A new exactly solvable relativistic periodic potential is obtained by the periodic extension of a well-known transparent scalar potential. It is found that the energy band edges ar…
Intertwining technique for the one-dimensional stationary Dirac equation
L. M. Nieto, A. A. Pecheritsin, Boris F. Samsonov
The technique of differential intertwining operators (or Darboux transformation operators) is systematically applied to the one-dimensional Dirac equation. The following aspects ar…
Chains of Darboux transformations for the matrix Schroedinger equation
Boris F Samsonov, AA Pecheritsin
Chains of Darboux transformations for the matrix Schroedinger equation are considered. Matrix generalization of the well-known for the scalar equation Crum-Krein formulas for the r…
Supersymmetric manipulation of quasienergy states. Application to the Berry phase
B. F. Samsonov, M. L. Glasser, L. M. Nieto
Time-dependent supersymmetry allows one to delete quasienergy levels for time-periodic Hamiltonians and to create new ones. We illustrate this by examining an exactly solvable mode…
Nonlocal supersymmetric deformations of periodic potentials
David J. Fernandez C., Bogdan Mielnik, Oscar Rosas-Ortiz +1
Irreducible second-order Darboux transformations are applied to the periodic Schrodinger's operators. It is shown that for the pairs of factorization energies inside of the same fo…
The Phenomenon of Darboux Displacements
David J. Fernandez C., Bogdan Mielnik, Oscar Rosas-Ortiz +1
For a class of Schrodinger Hamiltonians the supersymmetry transformations can degenerate to simple coordinate displacements. We examine this phenomenon and show that it distinguish…
Discrete supersymmetries of the Schrodinger equation and non-local exactly solvable potentials
Boris F. Samsonov, A. A. Suzko
Using an isomorphism between Hilbert spaces and we consider Hamiltonians which have tridiagonal matrix representations (Jacobi matrices) in a discrete basis and an…
