A stochastic step flow model with growth in 1+1 dimensions
stochastic step flow model growth 1+1 dimensions
2015/10/16
Mathematical implications of adding Gaussian white noise to the Burton– Cabrera–Frank model for N terraces (‘gaps’) on a crystal surface are studied under external material deposition for large N. The...
Theory of cooling by flow through narrow pores
Dilution chillers cooling heat atoms quantum states
2014/12/20
We consider the possibility of adding a stage to a dilution refrigerator to provide additional cooling by “filtering out” hot atoms. Three methods are considered: (1) effusion, where holes having diam...
Deconfined criticality, runaway flow in the two-component scalar electrodynamics and weak first-order superfluid-solid transitions
The monte carlo model strong coupling mechanism weak coupling triple point coupling
2014/12/20
We perform a comparative Monte Carlo study of the easy-plane deconfined critical point (DCP) action and its short-range counterpart to reveal close similarities between the two models for intermediate...
Quantum-limited mass flow of liquid He-3
Quantum fluid nano channel quantized conductance sensitive to temperature scattering matrix simulation
2014/12/19
We consider theoretically the possibility of observing unusual quantum fluid behavior in liquid 3He and solutions of 3He in 4He systems confined to nanochannels. In the case of pure ballistic flow at ...
Peristaltic flow of a fluid in a porous channel: A study having relevance to flow of bile within ducts in a pathological state
Peristaltic Transport Darcy Number Porosity Velocity Profile Critical Pressure
2011/9/22
Abstract: The paper deals with a theoretical study of the transport of a fluid in a channel, which takes place by the phenomenon of peristalsis. A mathematical analysis of the said problem has been pr...
