چکیده
In my research career in the field of quantum turbulence, I have been encouraged by Vinen. this article, review works motivated him and joint collaborations with him. Vinen me studies on turbulence at zero temperature, Kolmogorov spectrum a vortex tangle without mutual friction, fully coupled dynamics quantized vortices normal fluid. Joint include diffusion tangle, Kelvin wave cascade, created an oscillating object, tracer particles vortices.

Quantum Turbulence Decay
We develop a computational model of quantum turbulence decay employing a kinematic prescription for the normal fluid. We find that after an initial transient, the length of the vortex tangle L decreases and for large times obeys the scaling law L ≈ t−0.45. The average magnitude (along the quantized vortices) of the superfluid and line-vortex velocity are close and differ significantly from the ...
متن کاملIntroduction to quantum turbulence.
The term quantum turbulence denotes the turbulent motion of quantum fluids, systems such as superfluid helium and atomic Bose-Einstein condensates, which are characterized by quantized vorticity, superfluidity, and, at finite temperatures, two-fluid behavior. This article introduces their basic properties, describes types and regimes of turbulence that have been observed, and highlights similar...
متن کاملQuantum Weak Turbulence
The study of the phenomenon of quantum weak turbulence is extended by determining the quasiparticle spectrum associated with such a system using a Green’s function approach. The quasiparticle spectrum calculated establishes the dissipative regime and the inertial regime, hence a Kolmogorov type of picture. PACS number(s): 47.27.Ak, 67.40.Db, 67.40.Vs, 03.40.Gc
متن کاملAB INITIO QUANTUM CHEMICAL STUDIES IN CTAB
Quaternary ammonium compounds (QACS) are employed both as disinfectants for manual processing lines and surfaces in the food industry, and in human medicine area. QACS also cause cell death by protein denaturation . One of the QAC is cetyl trimethyl ammonium bromide (CTAB) that appears to rapture the cell membrane. The primary site of action of CTAB has been suggested to be the lipid components...
متن کاملThermal dissipation in quantum turbulence.
The microscopic mechanism of thermal dissipation in quantum turbulence is numerically studied by solving the coupled system involving the Gross-Pitaevskii equation and the Bogoliubov-de Gennes equation. At low temperatures, the obtained dissipation does not work at scales greater than the vortex core size. However, as the temperature increases, dissipation works at large scales and it affects t...
