Cooling with a subsonic flow of quantum fluid
Pantxo Diribarne, Bernard Rousset, Yuri A. Sergeev +3
Miniature heaters are immersed in flows of quantum fluid and the efficiency of heat transfer is monitored versus velocity, superfluid fraction and time. The fluid is He helium…
Superfluid turbulence driven by cylindrically symmetric thermal counterflow
E. Rickinson, C. F. Barenghi, Y. A. Sergeev +1
We show by direct numerical simulations that the turbulence generated by steadily heating a long cylinder immersed in helium~II is strongly inhomogeneous and consists of a dense tu…
Turbulent radial thermal counterflow in the framework of the HVBK model
Yuri A. Sergeev, Carlo F. Barenghi
We apply the coarse-grained Hall-Vinen-Bekarevich-Khalatnikov (HVBK) equations to model the statistically steady-state, turbulent, cylindrically symmetric radial counterflow genera…
Second harmonic generation in graphene dressed by a strong terahertz field
Mikhail Tokman, Sergei B. Bodrov, Yuri A. Sergeev +5
We observe enhanced second-harmonic generation in monolayer graphene in the presence of an ultra-strong terahertz field pulse with a peak amplitude of 250 kV/cm. This is a strongly…
Visualization of quantum turbulence in superfluid He-B: Combined numerical/experimental study of Andreev reflection
Viktor Tsepelin, Andrew W. Baggaley, Yuri A. Sergeev +5
We present a combined numerical and experimental study of Andreev scattering from quantum turbulence in superfluid He-B at ultralow temperatures. We simulate the evolution of m…
Optical emission of graphene and electron-hole pair production induced by a strong THz field
I. V. Oladyshkin, S. B. Bodrov, Yu. A. Sergeev +3
We report on the first experimental observation of graphene optical emission induced by the intense THz pulse. P-doped CVD graphene with the initial Fermi energy of about 200 meV w…
