A Dynamical Principle For 3D-4D Interlinkage In Salpeter-like Equations [PDF]

open access: yes, 2001
The half-century old Markov-Yukawa Transversality Principle ($MYTP$) which provides a theoretical rationale for the covariant instantaneous approximation ($CIA$) that underlies all Salpeter-like equations, is generalized to a covariant null-plane ansatz (

A Dynamical Principle For The Salpeter Equation [PDF]

open access: yes, 2000
The `Salpeter Equation' which has long been known as the 3D version of the 4D Bethe-Salpeter Equation under the Instantaneous Approximation, has a well-defined rationale that stems from the half-century old Markov-Yukawa Transversality Principle (MYTP ...

N=4 Supersymmetric MICZ-Kepler systems on S3

open access: yes, 2007
Proceeding from the superfield action for $N=4, d=1$ nonlinear supermultiplet, equipped with the most general potential term, we find the action describing a charged particle on the sphere $S^3$ in the field of $n$ fixed Dirac dyons.

The Schrödinger–Newton equation and its foundations

open access: yesNew Journal of Physics, 2014
The necessity of quantising the gravitational field is still subject to an open debate. In this paper we compare the approach of quantum gravity, with that of a fundamentally semi-classical theory of gravity, in the weak-field non-relativistic limit.

On the bound-state solutions of the Manning-Rosen potential including improved approximation to the orbital centrifugal term

open access: yes, 2011
The approximate analytical bound state solution of the Schr\"odinger equation for the Manning-Rosen potential is carried out by taking a new approximation scheme to the orbital centrifugal term. The Nikiforov-Uvarov method is used in the calculations. We

Testing time reversal symmetry in artificial atoms

open access: yesNew Journal of Physics, 2015
Over the past several decades, a rich series of experiments has repeatedly verified the quantum nature of superconducting devices, leading some of these systems to be regarded as artificial atoms.

Scattering theory of walking droplets in the presence of obstacles

open access: yesNew Journal of Physics, 2016
We aim to describe a droplet bouncing on a vibrating bath using a simple and highly versatile model inspired from quantum mechanics. Close to the Faraday instability, a long-lived surface wave is created at each bounce, which serves as a pilot wave for ...

Theory of nuclear spin dephasing and relaxation by optically illuminated nitrogen-vacancy center

open access: yesNew Journal of Physics, 2015
Dephasing and relaxation of the nuclear spins coupled to the nitrogen-vacancy (NV) center during optical initialization and readout is an important issue for various applications of this hybrid quantum register.

Imprecise probability for non-commuting observables

open access: yesNew Journal of Physics, 2015
It is known that non-commuting observables in quantum mechanics do not have joint probability. This statement refers to the precise (additive) probability model.

Equation of State of an Anyon Gas in a Strong Magnetic Field

open access: yes, 1993
The statistical mechanics of an anyon gas in a magnetic field is addressed. An harmonic regulator is used to define a proper thermodynamic limit. When the magnetic field is sufficiently strong, only exact $N$-anyon groundstates, where anyons occupy the ...
