摘要:We study the gate hysteresis behavior in single electron transport driven by surface acoustic wave (SAW/SET) devices over a wide temperature range from 1.7 to 200 K. From the temperature dependence, we come to the conclusion that the gate hysteresis in SAW/SET devices arises from...

摘要:Based on our current understanding of statistics of quantum turbulence as well as on results of intensive ongoing analytical, numerical and experimental studies, we overview here the following problems in the large-scale, space-homogeneous, steady-state turbulence of superfluid \...

摘要:We theoretically investigate the shear viscosity \(\eta \) , as well as the entropy density s , in the normal state of an ultracold Fermi gas. Including pairing fluctuations within the framework of a T -matrix approximation, we calculate these quantities in the Bardeen–Coope...

摘要:We report direct optical observation of cavitation bubbles in liquid helium, both in classical viscous He I and in superfluid He II, close to the \(\lambda \) -transition. Heterogenous cavitation due to the fast-flowing liquid over the rough surface of prongs of a quartz tuning f...

摘要:We measured the dependences of the resonance frequency of tuning forks immersed in liquid helium at \(T = 0.365\hbox { K}\) in the pressure interval from saturated vapor pressure to 24.8 atm. The quartz tuning forks have been studied with different resonance frequencies of 6.65, ...

摘要:The ground state of a spin-orbit-coupled Bose gas in a one-dimensional optical lattice is known to exhibit a mixed regime, where the condensate wave function is given by a superposition of multiple Bloch-wave components, and an unmixed one, in which the atoms occupy a single Bloc...

摘要:We study the response of one-dimensional liquid \(^4\hbox {He}\) to weak perturbations relying on the dynamical structure factor, \(S(q,\omega )\) , recently obtained via ab-initio techniques (Bertaina et al. in Phys Rev Lett 116:135302, 2016 ). We evaluate the drag force, \(F_\m...

摘要:Ultracold atomic Fermi gases in two dimensions (2D) are an increasingly popular topic of research. The interaction strength between spin-up and spin-down particles in two-component Fermi gases can be tuned in experiments, allowing for a strongly interacting regime where the gas p...

摘要:When an electron is forced into liquid \(^3\) He, it forms an “electron bubble”, a heavy ion with radius, \(R\simeq 1.5\) nm, and mass, \(M\simeq 100\,m_3\) , where \(m_3\) is the mass of a \(^3\) He atom. These negative ions have proven to be powerful local probes of the ph...

摘要:This paper presents results of an experimental study of the influence of deposition temperature on the refractive indices of methane in the form of cryovacuum deposited thin films. The experiments were performed in the vicinity of temperature of methane phase transition \(T=...
