Critical Dynamics of Spin Boson Model
M. G. Vasin, S. V. Remizov, A. A. Elistratov
In this work, we study the low-energy properties of the spin-boson model (SBM), which describes the dynamics of a spin-1/2 coupled to a bosonic environment characterized by a power…
Glass transition as a topological phase transition
Mikail Vasin
The glass transition is considered as a phase transition in the system of topologically protected excitations in matter structure. The critical behavior of the system is considered…
Berezinskii-Kosterlitz-Thouless transition close to zero temperature
Mikhail Vasin
The Berezinskii-Kosterlitz-Thouless (BKT) phase transition is considered in the condition of lowest temperatures, when thermal fluctuations give place to quantum ones. For this goa…
Composition heterogeneity influence on the phase formation dynamics in the Al-Y melt
V. G. Lebedev, A. A. Lebedeva, M. G. Vasin
It is shown that at a description of a binary solution, in the presence of a liquid phase of variable composition and a stoichiometric solid phase, the concept of chemical potentia…
Bose system critical dynamics near quantum phase transition
M. G. Vasin, V. M. Vinokur
We show that the change of the fluctuation spectrum near the quantum critical point (QCP) may result in the continuous change of critical exponents with temperature due to the incr…
To understanding of slow and non-monotonic relaxation in Al--Y eutectic melts
Mikhail G. Vasin, Vladimir G. Lebedev
We discuss the nature of the slow relaxation processes in glass-forming eutectic melts right after melting. For specific, we focus on the binary metallic melt Al--Y, which in addit…
