Method of canonical transformations in the theory of quantum gases interacting with radiation
M. S. Bulakhov, A. S. Peletminskii, P. P. Kostrobij +2
An approach to the theoretical study of effects and phenomena in quantum gases interacting with radiation is proposed. The approach is based on a modification of the canonical tran…
Multifractional Brownian motion with telegraphic, stochastically varying exponent
Michał Balcerek, Samudrajit Thapa, Krzysztof Burnecki +4
The diversity of diffusive systems exhibiting long-range correlations characterized by a stochastically varying Hurst exponent calls for a generic multifractional model. We present…
Being Heterogeneous Is Advantageous: Extreme Brownian Non-Gaussian Searches
Vittoria Sposini, Sankaran Nampoothiri, Aleksei Chechkin +3
Redundancy in biology may be explained by the need to optimize extreme searching processes, where one or few among many particles are requested to reach the target like in human fe…
Being heterogeneous is disadvantageous: Brownian non-Gaussian searches
Vittoria Sposini, Sankaran Nampoothiri, Aleksei Chechkin +3
Diffusing diffusivity models, polymers in the grand canonical ensemble and polydisperse, and continuous-time random walks all exhibit stages of non-Gaussian diffusion. Is non-Gauss…
Time-fractional Caputo derivative versus other integro-differential operators in generalized Fokker-Planck and generalized Langevin equations
Qing Wei, Wei Wang, Hongwei Zhou +2
Fractional diffusion and Fokker-Planck equations are widely used tools to describe anomalous diffusion in a large variety of complex systems. The equivalent formulations in terms o…
The modification of exponents in the Ginzburg-Sobyanin theory of superfluidity
Yu. M. Poluektov
A suggested amendment to the temperature dependencies in the thermodynamic potential of the Ginzburg-Sobyanin theory of superfluidity, which makes it possible to obtain critical ex…
