Two types of Hc2(T) dependences in Bi_2Sr_2Ca_(1-x)Y_xCu_2O_(8+delta) with different Yttrium content

I. L. Landau, H. Keller

We reanalyze the magnetization data collected on Bi_2Sr_2Ca_(1-x)Y_xCu_2O_(8+y) samples (Kim at al, Phys. Rev. B 72, 64525 (2005)) and argue that the method, which was used for the…

Influence of Strain on the Kinetics of Phase Transitions in Solids

Efim A. Brener, V. I. Marchenko, R. Spatschek

We consider a sharp interface kinetic model of phase transitions accompanied by elastic strain, together with its phase-field realization. Quantitative results for the steady-state…

Transition to Superfluid Turbulence

V. B. Eltsov, M. Krusius, G. E. Volovik

Turbulence in superfluids depends crucially on the dissipative damping in vortex motion. This is observed in the B phase of superfluid 3He where the dynamics of quantized vortices…

Quartz Tuning Fork: Thermometer, Pressure- and Viscometer for Helium Liquids

R. Blaauwgeers, M. Blazkova, M. Clovecko +10

Commercial quartz oscillators of the tuning-fork type with a resonant frequency of ~32 kHz have been investigated in helium liquids. The oscillators are found to have at best Q val…

Measurement of the Temperature Dependence of the Casimir-Polder Force

J. M. Obrecht, R. J. Wild, M. Antezza +3

We report on the first measurement of a temperature dependence of the Casimir-Polder force. This measurement was obtained by positioning a nearly pure 87-Rb Bose-Einstein condensat…

Longitudinal NMR and Spin States in the A-like Phase of 3He in Aerogel

V. V. Dmitriev, L. V. Levitin, N. Mulders +1

It was found that two different spin states of the A-like phase can be obtained in aerogel sample. In one of these states we have observed the signal of the longitudinal NMR, while…

Small-scale phase separation in doped anisotropic antiferromagnets

M. Yu. Kagan, K. I. Kugel, A. L. Rakhmanov +1

We analyze the possibility of the nanoscale phase separation manifesting itself in the formation of ferromagnetic (FM) polarons (FM droplets) in the general situation of doped anis…

Collective mode of homogeneous superfluid Fermi gases in the BEC-BCS crossover

R. Combescot, M. Yu. Kagan, S. Stringari

We perform a detailed study of the collective mode across the whole BEC-BCS crossover in fermionic gases at zero temperature, covering the whole range of energy beyond the linear r…

Dynamic Remanent Vortices in Superfluid 3He-B

R. E. Solntsev, R. de Graaf, V. B. Eltsov +2

We investigate the decay of vortices in a rotating cylindrical sample of 3He-B, after rotation has been stopped. With decreasing temperature vortex annihilation slows down as the d…

Casimir-Lifshitz force out of thermal equilibrium and asymptotic non-additivity

Mauro Antezza, Lev P. Pitaevskii, Sandro Stringari +1

We investigate the force acting between two parallel plates held at different temperatures. The force reproduces, as limiting cases, the well known Casimir-Lifshitz surface-surface…

Stability and excitations of solitons in 2D Bose-Einstein condensates

S. Tsuchiya, F. Dalfovo, C. Tozzo +1

The small oscillations of solitons in 2D Bose-Einstein condensates are investigated by solving the Kadomtsev-Petviashvili equation which is valid when the velocity of the soliton a…

Dynamics of vortices and interfaces in superfluid 3He

A. P. Finne, V. B. Eltsov, R. Hanninen +5

Rapid new developments have occurred in superfluid hydrodynamics since the discovery of a host of unusual phenomena which arise from the diverse structure and dynamics of quantized…

On 't Hooft's representation of the β-function

I. M. Suslov

It is demonstrated, that 't Hooft's renormalization scheme (in which β-function has exactly the two-loop form) is generally in conflict with the natural physical requirements and s…
