Critical stability of few-body systems
V. A. Karmanov, J. Carbonell
When a two-body system is bound by a zero-range interaction, the corresponding three-body system -- considered in a non-relativistic framework -- collapses, that is its binding ene…
Quantum strong subadditivity condition for systems without subsystems
Margarita A Man'ko, Vladimir I Man'ko
The strong subadditivity condition for the density matrix of a quantum system, which does not contain subsystems, is derived using the qudit-portrait method. An example of the qudi…
Example of a stable wormhole in general relativity
K. A. Bronnikov, L. N. Lipatova, I. D. Novikov +1
We study a static, spherically symmetric wormhole model whose metric coincides with that of the so-called Ellis wormhole but the material source of gravity consists of a perfect fl…
Wigner functions and spin tomograms for qubit states
Peter Adam, Vladimir A. Andreev, Iulia Ghiu +3
We establish the relation of the spin tomogram to the Wigner function on a discrete phase space of qubits. We use the quantizers and dequantizers of the spin tomographic star-produ…
Algebras with convergent star products and their representations in Hilbert spaces
Michael A. Soloviev
We study star product algebras of analytic functions for which the power series defining the products converge absolutely. Such algebras arise naturally in deformation quantization…
Quantum Reflection of Antihydrogen in the GBAR Experiment
Gabriel Dufour, Romain Guérout, Astrid Lambrecht +3
In the GBAR experiment, cold antihydrogen atoms will be left to fall on an annihilation plate with the aim of measuring the gravitational acceleration of antimatter. Here, we study…
Enhancement of ultrafast electron photoemission from metallic nano antennas excited by a femtosecond laser pulse
M. A. Gubko, W. Husinsky, A. A. Ionin +7
We have demonstrated for the first time that an array of nanoantennas (central nanotips inside sub-micron pits) on an aluminum surface, fabricated using a specific double-pulse fem…
Shaping the distribution of vertical velocities of antihydrogen in GBAR
Gabriel Dufour, Pascal Debu, Astrid Lambrecht +3
GBAR is a project aiming at measuring the free fall acceleration of gravity for antimatter, namely antihydrogen atoms (). Precision of this timing experiment…
Representations of at even roots of unity
A M Semikhatov, I Yu Tipunin
We construct all projective modules of the restricted quantum group at an even, th, root of unity. This -dimensional Hopf algebra is a common doub…
Discrete spectrum of kink velocities in Josephson structures: the nonlocal double sine-Gordon model
G. L. Alfimov, A. S. Malishevskii, E. V. Medvedeva
We study a model of Josephson layered structure which is characterized by two peculiarities: (i) superconducting layers are thin; (ii) due to suppression of superconducting states…
To the Origin of Anomalous Torque Acting on a Rotating Magnetized Ball in Vacuum
V. S. Beskin, A. A. Zheltoukhov, A. K. Obukhova +1
The magnitude of the anomalous torque acting on a rotating magnetized ball in vacuum is specified. Its value is shown to depend on the magnetic field structure inside the body.
Study of EUV Emission and Properties of a Coronal Streamer from PROBA2/SWAP, Hinode/EIS and Mauna Loa Mk4 Observations
F. Goryaev, V. Slemzin, L. Vainshtein +1
Wide-field EUV telescopes imaging in spectral bands sensitive to 1 MK plasma on the Sun often observe extended ray-like coronal structures stretching radially from active regions t…
Dynamics-generating semigroups and phenomenology of decoherence
Michael B. Mensky
The earlier proposed Dynamics-Generating Approach (DGA) is reviewed and extended. Starting from an arbitrarily chosen group or semigroup which have structure similar to the structu…
Present status of the Bethe-Salpeter approach in Minkowski space
V. A. Karmanov
Recently developed methods allowing to find the solutions of the Bethe-Salpeter equations in Minkowski space, both for the bound and scattering states, are reviewed. For the bound…
Nonperturbative calculations in truncated Fock space in LFD
V. A. Karmanov
A non-perturbative approach based on the Fock decomposition of the state vector and its truncation is discussed. In order the non-perturbative renormalization procedure after trunc…
Search for a multi-Higgs-boson cascade in WWbb events with the ATLAS detector in pp collisions at sqrt(s) = 8 TeV
ATLAS Collaboration
A search is presented for new particles in an extension to the Standard Model that includes a heavy Higgs boson H0, an intermediate charged Higgs boson pair H+-, and a light Higgs…
Quasi-free photoproduction of eta-mesons off 3He nuclei
L. Witthauer, D. Werthmueller, I. Keshelashvili +70
Quasi-free photoproduction of -mesons has been measured off nucleons bound in He nuclei for incident photon energies from the threshold region up to 1.4 GeV. The experiment…
Photoelectron emission from plasmonic nanoparticles: Comparison between surface and volume photoelectric effects
Alexander V. Uskov, Igor E. Protsenko, Renat Sh. Ikhsanov +5
We study emission of photoelectrons from plasmonic nanoparticles into surrounding matrix. We consider two mechanisms of the photoelectric effect from nanoparticles - surface and vo…
Finite field-energy of a point charge in QED
Caio V. Costa, Dmitri M. Gitman, Anatoly E. Shabad
We consider a simple nonlinear (quartic in the fields) gauge-invariant modification of classical electrodynamics, which possesses a regularizing ability sufficient to make the fiel…
Subcritical mirror structures in an anisotropic plasma
E. A. Kuznetsov, T. Passot, V. P. Ruban +1
Based on Grad-Shafranov-like equations, a gyrotropic plasma where the pressures in the static regime are only functions of the amplitude of the local magnetic field is shown to be…
Search for long-lived stopped R-hadrons decaying out-of-time with pp collisions using the ATLAS detector
ATLAS Collaboration
An updated search is performed for gluino, top squark, or bottom squark R-hadrons that have come to rest within the ATLAS calorimeter, and decay at some later time to hadronic jets…
