Model of a relativistic oscillator in a generalized Schrödinger
In a generalized Schrödinger picture, the authors consider the motion of a
relativistic particle in an external field (like in the case of a harmonic oscillator). In this picture the analogs of the Schrödinger operators of the particle are
independent of both the time and the space coordinates. These operators induce operators which are related to Killing vectors of the Anti de Sitter (AdS)
space. The nonrelativistic limit is also considered

On the nature of a∗k ak and the emergence of the Born rule
This paper is intended to show that a review in the concept of the game theoretical utility, the revised utility to be applied to the definition of the utility of
a wave function representing an object subsystem relative to its observer subsystem, both within an isolated system, leads to the emergence of Max Born’s
rule as a profit under a von Neumann good measure game.

Electron on a cylinder with topological defects in a homogeneous
magnetic field
In this work the authors study the effects of
the geometry and topology of a cylinder on
the energy levels of an electron moving in
a homogeneous magnetic field. They consider the existence of topological defects
as a screw dislocation and a disclination.
When they take the region of movement as
the full cylindrical surface, they find that,
by increasing the strength of the screw dislocation, the dispersion on the electronic energy levels is affected and monotonically increasing.

Relativistic Anandan quantum phase in the Lorentz violation
The authors study the influence of a classical background based on the violation of the Lorentz symmetry on the relativistic Anandan quantum phase.
They show that the choice of the Lorentz symmetry violation background provides an abelian contribution for the relativistic Anandan quantum phase.

Next-to-next-to-leading order post-Newtonian spin(1)-spin(2)
Hamiltonian for self-gravitating binaries
The authors present the next-to-next-to-leading order post-Newtonian (PN)
spin(1)-spin(2) Hamiltonian for two self-gravitating spinning compact objects.
If both objects are rapidly rotating, then the corresponding interaction is comparable in strength to a 4PN effect. The Hamiltonian is checked via the global
Poincaré algebra with the center-of-mass vector uniquely determined by an

Quantum anticentrifugal potential in a bent waveguide
The authors show the existence of an anticentrifugal force for a quantum particle in
a bent waveguide. This effect may be observed in interference experiments which
are sensitive to the additional phase of the
wavefunction gained in the bent regions
and can find application in distinguishing
between straight and bent geometries.

Quantum mechanics needs no consciousness
It has been suggested that consciousness
plays an important role in quantum mechanics as it is necessary for the collapse
of wave function during the measurement.
Here the authors formulated several predictions that follow from this hypothetical relationship and that can be empirically tested. Experimental results that are
already available suggest falsification of
these predictions. Thus, the suggested link
between human consciousness and collapse
of wave function does not seem viable.

Neutron bound states in a supersymmetric double Dirac delta
electrostatic potential
The authors study neutron bound states
in a particular (1 + 1)-supersymmetric
configuration. A simple physical setup
is chosen so that the effective interaction becomes a particular kind of double Dirac delta potential. In this configuration it is shown that the neutron
distinguishes between positive and negative electric charge as a consequence
of a purely quantum mechanical effect.
The theoretical background is presented
and a possible application to a real-life physical system is discussed.

Comment on “Strong signature of the active Sun in 100 years of
terrestrial insolation data” by W. Weber
An analysis of ground-based observations of solar irradiance was recently
published in this journal, reporting an
apparent increase of solar irradiance
on the ground of the order of 1% between solar minima and maxima. Since
the corresponding variations in total
solar irradiance on top of the atmosphere are accurately determined from satellite observations to be of the order of 0.1% only, the one order of magnitude
stronger effect in the terrestrial insolation data was interpreted as evidence
for cosmic-ray induced aerosol formation in the atmosphere. In the author’s
opinion, however, this result does not reflect reality. Using the energy budget
of Earth’s surface, he shows that changes of ground-based insolation with the
solar cycle of the order of 1% between solar minima and maxima would result in large surface air temperature variations which are inconsistent with the
instrumental record. It would appear that the strong variations of terrestrial
irradiance found by Weber are due to the uncorrected effects of volcanic or
local aerosols and seasonal variations. Taking these effects into account, the
author finds a variation of terrestrial insolation with solar activity which is of
the same order as the one measured from space, bringing the surface energy
budget into agreement with the solar signal detected in temperature data.

Reply to the Comment of G. Feulner
In his reply the author present a reanalysis of the data of the Smithsonian
Astrophysical Observatory (SAO). For
this, a new data reduction method is introduced, allowing a drastic lowering
of data scatter, so that the time series
of the reduced data clearly shows the
≈ 1% variation of the terrestric solar
irradiance in parallel with solar activity. The implications are discussed.

Optical properties of nitride nanostructures
[Ann. Phys. (Berlin) 523, 51 (2011)]
The set of InN nanocolumn samples discussed in the article was not grown
using Au as a catalyst. Instead, the growth was performed catalyst-free by
plasma-assisted molecular beam epitaxy.
