Lorentz quantum mechanics

New Journal of Physics, 2018
We present a theoretical framework for the dynamics of bosonic Bogoliubov quasiparticles. We call it Lorentz quantum mechanics because the dynamics is a continuous complex Lorentz transformation in complex Minkowski space.

Hamiltonian reduction and supersymmetric mechanics with Dirac monopole

, 2006
We apply the technique of Hamiltonian reduction for the construction of three-dimensional ${\cal N}=4$ supersymmetric mechanics specified by the presence of a Dirac monopole. For this purpose we take the conventional ${\cal N}=4$ supersymmetric mechanics

Probabilistically cloning two single-photon states using weak cross-Kerr nonlinearities

New Journal of Physics, 2014
By using quantum nondemolition detectors (QNDs) based on weak cross-Kerr nonlinearities, we propose an experimental scheme for achieving $1\to 2$ probabilistic quantum cloning (PQC) of a single-photon state, secretly choosing from a two-state set. In our

The existence problem for dynamics of dissipative systems in quantum probability

, 2004
Motivated by existence problems for dissipative systems arising naturally in lattice models from quantum statistical mechanics, we consider the following $C^{\ast}$-algebraic setting: A given hermitian dissipative mapping $\delta$ is densely defined in a

Supersymmetric quantum mechanics based on higher excited states

, 1996
We generalize the formalism and the techniques of the supersymmetric (susy) quantum mechanics to the cases where the superpotential is generated/defined by higher excited eigenstates.

Quantum mechanics with geometric constraints of Friedmann type

Open Physics, 2017
The paper presents the study of quantum mechanics of a free particle with the constraints in the phase space, the canonical equations, which are the geometrical constraints of Friedmann type. It has been proved that the constraints can imitate force.
