On the Topological Features of the Helical Phase Transition in MnSi
S. M. Stishov, A. E. Petrova, A. M. Belemuk
Many decades of study have revealed very unusual properties of the helical phase transition in MnSi. This situation is briefly described and illustrated in the present note. As one…
Spin-fluctuation heat capacity at magnetic phase transition in the Co,Fe doped MnSi
S. M. Stishov, A. E. Petrova, A. M. Belemuk
An universal line revealing an independence of spin fuctuation contributions to the heat capacity on impurity content and its nature is discovered in the helical phase of Mn(Co,Fe)…
Quantum criticality features in the Co doped MnSi
A. E. Petrova, A. M. Belemuk, S. M. Stishov
The mysterious universal line revealing an independence of spin fluctuation contributions to the heat capacity of (Mn,Co)Si on impurity contents and its nature is discovered. This…
Quantum phase transitions and the degree of nonidentity in the system with two different species of vector bosons
A. M. Belemuk, N. M. Chtchelkatchev, A. V. Mikheyenkov +1
We address the system with two species of vector bosons in an optical lattice. In addition to the the standard parameters characterizing such a system, we are dealing here with the…
Magnetic phase diagram and quantum phase transitions in a two-species boson model
A. M. Belemuk, N. M. Chtchelkatchev, A. V. Mikheyenkov +1
We analyze the possible types of ordering in a boson--fermion model. The Hamiltonian is inherently related to the Bose--Hubbard model for vector two-species bosons in optical latti…
Monte Carlo modeling the phase diagram of magnets with the Dzyaloshinskii - Moriya interaction
A. M. Belemuk, S. M. Stishov
We use classical Monte Carlo calculations to model the high-pressure behavior of the phase transition in the helical magnets. We vary values of the exchange interaction constant J…
