Welcher Weg? A trajectory representation of a quantum Young's diffraction experiment [PDF]

, 2006
The double slit problem is idealized by simplifying each slit by a point source. A composite reduced action for the two correlated point sources is developed.

Deformed nuclear halos [PDF]

, 1996
Deformation properties of weakly bound nuclei are discussed in the deformed single-particle model. It is demonstrated that in the limit of a very small binding energy the valence particles in specific orbitals, characterized by a very small projection of

Nanomechanics of a Hydrogen Molecule Suspended between Two Equally Charged Tips [PDF]

, 2019
Geometric configuration and energy of a hydrogen molecule centered between two point-shaped tips of equal charge are calculated with the variational quantum Monte-Carlo (QMC) method without the restriction of the Born-Oppenheimer (BO) approximation ...

Generalized r-Modes of the Maclaurin Spheroids [PDF]

, 1998
Analytical solutions are presented for a class of generalized r-modes of rigidly rotating uniform density stars---the Maclaurin spheroids---with arbitrary values of the angular velocity.

Horizon Quantum Mechanics for spheroidal sources

, 2018
We start investigating the extension of the Horizon Quantum Mechanics to the case of spheroidal sources. We first study the location of trapping surfaces in space-times resulting from an axial deformation of static isotropic systems, and show that the ...

High accuracy binary black hole simulations with an extended wave zone [PDF]

, 2009
We present results from a new code for binary black hole evolutions using the moving-puncture approach, implementing finite differences in generalised coordinates, and allowing the spacetime to be covered with multiple communicating non-singular ...

Simplified method for analytically determining the external magnetostatic field of uncertain extended technical objects based on near-field measurements

Electrical engineering & Electromechanics
Introduction. An important scientific and technical problem of magnetism of uncertain extended energy-saturated objects - such as naval vessels and submarines is implementation of strict requirements for magnetic silence based on mathematical modeling of

Multispheroidal model of magnetic field of uncertain extended energy-saturated technical object

Electrical engineering & Electromechanics
Problem. The implementation of strict requirements for magnetic silence of elongated energy-saturated technical objects – such as naval vessel and submarines is largely determined by the adequacy of mathematical models to the signatures of a real ...

Five-dimensional Janis-Newman algorithm

, 2015
The Janis-Newman algorithm has been shown to be successful in finding new sta- tionary solutions of four-dimensional gravity. Attempts for a generalization to higher dimensions have already been found for the restricted cases with only one angular mo ...
