Generalized Deformed Commutation Relations with Nonzero Minimal Uncertainties in Position and/or Momentum and Applications to Quantum Mechanics

Quesne, C.; Tkachuk, V.M. (Symmetry, Integrability and Geometry: Methods and Applications, 2007)

Two generalizations of Kempf's quadratic canonical commutation relation in one dimension are considered. The first one is the most general quadratic commutation relation. The corresponding nonzero minimal uncertainties in ...
Geometric characteristics of quantum evolution: curvature and torsion

Laba, H.P.; Tkachuk, V.M. (Condensed Matter Physics, 2017)

We study characteristics of quantum evolution which can be called curvature and torsion. The curvature shows a deviation of the state vector in quantum evolution from the geodesic line. The torsion shows a deviation ...
Geometric measure of mixing of quantum state

Laba, H.P.; Tkachuk, V.M. (Condensed Matter Physics, 2018)

We define the geometric measure of mixing of quantum state as a minimal Hilbert-Schmidt distance between the mixed state and a set of pure states. An explicit expression for the geometric measure is obtained. It is interesting ...
Supersymmetric method for constructing quasi-exactly solvable potentials

Tkachuk, V.M. (Condensed Matter Physics, 1999)

We propose a new method for constructing the quasi-exactly solvable (QES) potentials with two known eigenstates using supersymmetric quantum mechanics. General expression for QES potentials with ...
