A Potential of Incoherent Attraction Between Multidimensional Solitons

Andrey Maimistov, Boris Malomed, Anton Desyatnikov

We obtain analytical expressions for an effective potential of interaction between two- and three-dimensional (2D and 3D) solitons (including the case of 2D vortex solitons) belong…

The large-scale modulation of the density distribution in standard axionic CDM and its cosmological and physical impact

M. Yu. Khlopov, A. S. Sakharov, D. D. Sokoloff

It is shown, that the energy density of coherent axion field oscillations in the cosmology of standard invisible axion should be distributed in the Universe in the form of archiole…

Prismane C_8: A New Form of Carbon?

Leonid A. Openov, Vladimir F. Elesin

Our numerical calculations on small carbon clusters point to the existence of a metastable three-dimensional eight-atom cluster C which has a shape of a six-atom triangular pri…

Signature of relic heavy stable neutrinos in underground experiments

D. Fargion, M. Yu. Khlopov, R. V. Konoplich +1

Considering heavy stable neutrinos of 4th generation we calculate the relic density of such neutrinos in the Universe. Taking into account the condensation of heavy neutrinos in th…

Non-Dissipative Logic Device NOT Based on Two Coupled Quantum Dots

L. A. Openov, A. M. Bychkov

Non-dissipative dynamics of interacting electrons in two tunnel-coupled quantum dots is studied theoretically within the framework of the Hubbard model. Various values of intra-dot…

Galactic Gamma Halo by Heavy Neutrino annihilations?

Daniele Fargion, Rostislav Konoplich, Marco Grossi +1

The diffused gamma halo around our Galaxy recently discovered by EGRET could be produced by annihilations of relic neutrinos N (of fourth generation), whose mass is within a narrow…

The strength of the analog and Gamow-Teller giant resonances and hindrance of the 2νββ-decay rate

O. A. Rumyantsev, M. H. Urin

An approach for describing the hindrance of the nuclear 2νββ-decay amplitude is proposed. The approach is based on a new formula obtained by a model-independent transformation of t…

Antihelium flux signature for antimatter globular cluster in our Galaxy

K. M. Belotsky, Yu. A. Golubkov, M. Yu. Khlopov +2

The AMS experiment is shown to be sensitive to test the hypothesis on the existence of antimatter globular cluster in our Galaxy. The hypothesis follows from the analysis of possib…

Structure and decay properties of spin-dipole giant resonances within a semimicroscopical approach

E. A. Moukhai, V. A. Rodin, M. H. Urin

A semimicroscopical approach is applied to calculate: (i) strength functions for the charge-exchange spin-dipole giant resonances in the 208Pb parent nucleus; (ii) partial and tota…

Quantum spin chains in a magnetic field

V. A. Kashurnikov, N. V. Prokof'ev, B. V. Svistunov +1

We demonstrate that the ``worm'' algorithm allows very effective and precise quantum Monte Carlo (QMC) simulations of spin systems in a magnetic field, and its auto-correlation tim…
