Familon Model of Dark Matter
V. Burdyuzha, O. Lalakulich, Yu. Ponomarev +1
If the next fundamental level of matter occurs (preons) then dark matter must consist of familons containing a "hot" component from massless particles and a "cold" component from m…
The influence of ultra-high-energy cosmic rays on star formation in the early universe
E. O. Vasiliev, Yu. A. Shchekinov
The presence of ultra-high-energy cosmic rays (UHECR) results in an increase in the degree of ionization in the post-recombination Universe, which stimulates the efficiency of the…
Metastable states in disordered Ising magnets in mean-field approximation
P. N. Timonin
The mechanism of appearance of exponentially large number of metastable states in magnetic phases of disordered Ising magnets with short-range random exchange is suggested. It is b…
On absolute continuity of spectra of periodic elliptic operators
Peter Kuchment, Sergei Levendorski
The paper contains a brief description of a simplified version of A. Sobolev's proof of absolute continuity of spectra of periodic magnetic Schrödinger operators. This approach is…
Yangian Construction of the Virasoro Algebra
S. Z. Levendorskii, A. Sudbery
We show that a Yangian construction based on the algebra of an infinite number of harmonic oscillators (i.e. a vibrating string) terminates after one step, yielding the Virasoro al…
