Nonlinear Transformation for a Class of Gauged Schroedinger Equations with Complex Nonlinearities [PDF]

, 2002
In the present contribution we consider a class of Schroedinger equations containing complex nonlinearities, describing systems with conserved norm $|\psi|^2$ and minimally coupled to an abelian gauge field.

Fidelity-optimized quantum state estimation

New Journal of Physics, 2015
We describe an optimized, self-correcting procedure for the Bayesian inference of pure quantum states. By analyzing the history of measurement outcomes at each step, the procedure returns the most likely pure state, as well as the optimal basis for the ...

Symmetries of N=4 supersymmetric CP(n) mechanics

, 2012
We explicitly constructed the generators of $SU(n+1)$ group which commute with the supercharges of N=4 supersymmetric $\mathbb{CP}^n$ mechanics in the background U(n) gauge fields.

Second Hopf map and Yang-Coulomb system on 5d (pseudo)sphere

, 2009
Using the second Hopf map, we perform the reduction of the eight-dimensional (pseudo)spherical (Higgs)oscillator to a five-dimensional system interacting with a Yang monopole.

Noncommutativity in (2+1)-dimensions and the Lorentz group [PDF]

, 2012
In this article we considered models of particles living in a three-dimensional space-time with a nonstandard noncommutativity induced by shifting canonical coordinates and momenta with generators of a unitary irreducible representation of the Lorentz ...

Precise space–time positioning for entanglement harvesting

New Journal of Physics, 2016
We explore the crucial role of relative space–time positioning between the two detectors in an operational two-party entanglement-harvesting protocol.

Measurement of Superluminal optical tunneling times in double-barrier photonic bandgaps [PDF]

, 2002
Tunneling of optical pulses at 1.5 micron wavelength through double-barrier periodic fiber Bragg gratings is experimentally investigated. Tunneling time measurements as a function of barrier distance show that, far from the resonances of the structure ...

External field influence on semiflexible macromolecules: geometric coupling

, 2011
We suggested a geometric approach to address the external field influence on the DNA molecules, described by the WLC model via geometric coupling. It consists in the introduction of the effective metrics depending on the potential of the external field ...

Single electron relativistic clock interferometer

New Journal of Physics, 2016
Although time is one of the fundamental notions in physics, it does not have a unique description. In quantum theory time is a parameter ordering the succession of the probability amplitudes of a quantum system, while according to relativity theory each ...

Quantum supremacy of many-particle thermal machines

New Journal of Physics, 2016
While the emergent field of quantum thermodynamics has the potential to impact energy science, the performance of thermal machines is often classical.
