(2009)
In this work we report variational calculations of the two lowest vibrational states of the HD molecule within
the framework that does not assume the Born-Oppenheimer BO approximation. The nonrelativistic energies
of ...

Pavanello, Michele; Bubin, Sergiy; Molski, Marcin; Adamowicz, Ludwik
(2005)
Very accurate calculations of the pure vibrational spectrum of the HeH+ ion are reported. The
method used does not assume the Born–Oppenheimer approximation, and the motion of both the
electrons and the nuclei are treated ...

(2004)
Very accurate non-Born–Oppenheimer variational calculations of the ground state of e1LiH have been performed using explicitly correlated Gaussian functions with preexponential factors dependent on powers of the internuclear ...

Bubin, Sergiy; Adamowicz, Ludwik
(2006)
Very accurate, rigorous, variational, non-Born-Oppenheimer non-BO calculations have been performed for the fully symmetric, bound states of the LiH+ ion. These states correspond to the ground and excited vibrational ...

(2005)
We report fully nonadiabatic calculations of all rotationless bound states of HT+ molecular ion st+p+e−d carried out in the framework of the variational method. We show that, in all the states, except the two highest ones, ...

(Nazarbayev University School of Science and Technology, 2018-05-07)
The investigation of hyperbolic metamaterials, shows that metal layers that are part of graphene structures, and also types I and II layered systems, are readily controlled. Since graphene is a nicely conducting sheet it ...

(2004)
We took the complete nonrelativistic Hamiltonians for the LiH and LiH2 systems, as well as their deuterated isotopomers, we separated the kinetic energy of the center of mass motion from the Hamiltonians, and with the use ...

(2006)
Highly accurate ground-state nonrelativistic variational calculations of Ps2, 1HPs, and HPs are reported. The calculations have been performed using 5000 explicitly correlated Gaussian basis functions and yielded the ...

(2013-08-07)
We consider general relativistic homogeneous gravitational collapses for dust and radiation. We show that replacing the density profile with an effective density justified by some quantum gravity framework leads to the ...

The spin measurement of black holes has important implications in physics and astrophysics. Regardless of the specific technique to estimate the black hole spin, all the current approaches assume that the space-time geometry ...

(2009)
Nowadays, numerous fields such as High Energy Physics (HEP), medical imaging devices, portable radiation
detectors etc., require a robust, miniature, reliable and readily available photon detector that is stable in ...

(European Physical Journal C: Particles and Fields, 2017-07-11)
We study the observational properties of a class of exact solutions of Einstein’s field equations describing stationary, axially symmetric, rigidly rotating dust (i.e. noninteracting
particles).We ask the questionwhether ...

Good, Michael R.R.; Yelshibekova, Khalykbek; Chin Ong, Yen
(ArXiv, 2017-03-03)
A new solution of a unitary moving mirror is found to produce nite energy and emit thermal radiation despite the absence of an acceleration horizon. In the limit that the mirror approaches the speed of light, the model ...

A single real scalar field of spin zero obeying the Klein-Gordon equation in flat spacetime under external conditions is considered in the context of the spin-statistics connection. An imposed accelerated boundary on the ...

Valagiannopoulos, Constantinos
(IEEE Journal of Selected Topics in Quantum Electronics, 2015)
How one can fabricate the Parity-Time (PT) symmetric
siblings of commonly used metals in the visible? This
work tries to give an answer to that question by providing
the features of the active media which conjugately ...

(38th International Conference on High Energy Physics, 2016)
Nowadays, many particle detectors use liquid scintillator (LS) as a detection medium. In
particular, Water-based Liquid Scintillator (WbLS) that is a new material currently under
development. It is based on the idea of ...

(Metamaterials, 2018)
Structural boundaries, materials and feeding sources are the three fundamental segments
defining photonic devices. Since excitation is usually dictated by the application and there
are infinite ways to select the spatial ...

Lens design for focusing and imaging has been optimized through centuries of developments; however,
conventional lenses, even in their most ideal realizations, still suffer from fundamental limitations, such as
limits ...
