Valagiannopoulos, Constantinos; Tretyakov, Sergei A.
(American Physical Society, 2016-09-12)
Recently, it was shown that by using special artificial materials it is possible to ensure that all electromagnetic
modes of free space are conjugately matched to the modes of a material body and, thus, all modes deliver ...

(2013)
The variational method complemented with the use of explicitly correlated Gaussian basis functions
is one of the most powerful approaches currently used for calculating the properties of few-body
systems. Despite its ...

Malafarina, D.; Joshi, Pankaj S.
(2011-06-19)
It is known now that a typical gravitational collapse in general relativity, evolving from regular initial data and under physically reasonable conditions would end in either a black hole or a naked singularity final state. ...

Lochan, K.; Malafarina, D.; Singh, T.P.
(2010-09-23)
We investigate a possible way of establishing a parallel between the third law of black hole mechanics, and the strong version of the third law of thermodynamics. We calculate the surface gravity and area for a naked ...

Beznosko, Dmitriy
(2011)
The T2K experiment is a long-baseline neutrino oscillation experiment. Its main goal is to measure the last unknown lepton
sector mixing angle 13 by observing e appearance in a beam. It also aims to make a precision ...

Beznosko, Dmitriy
(2012)
The Pi-Zero detector (PØD) is one of the subdetectors that makes up the off-axis near detector for
the Tokai-to-Kamioka (T2K) long baseline neutrino experiment. The primary goal for the PØD
is to measure the relevant ...

Beznosko, Dmitriy
(2012)
The Tokai-to-Kamioka (T2K) experiment studies neutrino oscillations using an o -axis muon
neutrino beam with a peak energy of about 0.6 GeV that originates at the J-PARC accelerator
facility. Interactions of the neutrinos ...

(2008)
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 ...

Good, Michael R.R.; Anderson, Paul R.; Evans, Charles R.
(2013-03-28)
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 ...

(2015)
The alignment-dependent ionization of acetylene and ethylene in short laser pulses is investigated in the framework of the time-dependent density-functional theory coupled with Ehrenfest dynamics. The molecular alignment ...

Baris Bagci, G.; Oikonomou, Th.
(2013)
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, ...

Shena, J.; Hizanidis, J.; Kovanis, V.; Tsironis, G.P.
(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 ...

Bubin, Sergiy; Formanek, Martin; Adamowicz, Ludwik
(Chemical Physics Letters, 2016-03-01)
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 ...

Valagiannopoulos, Constantinos
(2016)
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, ...

Bubin, Sergiy; Adamowicz, Ludwik
(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 ...

Bubin, Sergiy; Stanke, Monika; Adamowicz, Ludwik
(2011)
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 ...

(Nanotechnology, 2017-10-20)
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 ...

(Optical Society of America, 2017-12-08)
Color-selective absorption of light is a very significant operation used in numerous applications, from photonic sensing and switching to optical signal modulation and energy harnessing. We demonstrate angle-insensitive ...

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 ...
