We have performed high-accuracy quantum mechanical calculations for the three lowest S states of the
beryllium ion 9Be+ . The nonrelativistic part of the calculations was done with the variational approach and
explicitly ...

Particle production due to a quantized, massless, minimally coupled scalar eld in two-dimensional at spacetime with an accelerating mirror is investigated, with a focus on the time dependence of the process. We analyze ...

It is often stated that heat bathswith finite degrees of freedom i.e., finite baths, are sources of Tsallis distributions for classical Hamiltonian systems. By using well-known fundamental statistical mechanics expressions, ...

Convective instabilities in the advanced stages of nuclear shell burning can play
an important role in neutrino-driven supernova explosions. In our previous work, we studied
the interaction of vorticity and entropy waves ...

(Nature Research, 2017-02)
Semiconductor laser arrays have been investigated experimentally and theoretically from the viewpoint of temporal and spatial coherence for the past forty years. In this work, we are focusing on a rather novel complex ...

Abstract Complex explicitly correlated one-center all-particle Gaussian functions (CECGs) are tested as basis functions for molecular non-Born–Oppenheimer (non-BO) calculations. The tests concern the complete spectrum of ...

One of the main problems when trying to detect
the position and other characteristics of a small inclusion into
lossy earth via external measurements is the inclusion’s poor
scattering response due to attenuation. Hence, ...

(Nazarbayev University School of Science and Technology, 2017-05)
Energy management in smart buildings and homes has become an important issue.
Proper energy management is judged upon the amount of consumed electrical energy
as well as the total electricity cost. In this master thesis, ...

(2003)
Very accurate, rigorous and fully variational, all-particle, non-Born–Oppenheimer calculations of the vibrational spectrum of the H2 molecule have been performed. Very high accuracy has been achieved by expanding the wave ...

(American Mathematical Monthly, 2016-10-01)
It is not hard to prove that a uniformly continuous real function, whose integral up to infinity exists, vanishes at infinity, and it is probably little known that this statement runs under the name "Barbalat's lemma." In ...

We recently presented very accurate calculations of the fundamental vibrational frequency of the 7LiH+ and 3He4He+ ions [Stanke et al., Phys. Rev. A 79, 060501(R) (2009)] performed without the Born–Oppenheimer approximation ...

The topics here deal with some current progress in electromagnetic wave propagation in a family of substances known as metamaterials. To begin with, it is discussed how a pulse can develop a leading edge that steepens and ...

Anomalous scattering effects (invisibility, superscattering, Fano resonances, etc) enabled by complex media and metamaterials
have been the subject of intense efforts in the past couple of decades. In this article, we ...

for surface-mounted permanent magnet synchronous motors
(PMSMs). By applying the θ-D method in both the ...
