Previous work has shown the detection of quantum turbulence with mechanical resonators but with limited spatial and temporal resolution. Here, the authors demonstrate real-time detection of single quantum vortices in superfluid 4He with millisecond a

Understanding dynamics of fermionic bound states is important for their potential application in quantum devices. Here the authors study zero temperature dynamics and dissipation of fermions bound on a moving goal-post shaped wire in superfluid 3He-B

Abstract Microelectromechanical (MEMS) and nanoelectromechanical systems (NEMS) are ideal candidates for exploring quantum fluids, since they can be manufactured reproducibly, cover the frequency range from hundreds of kilohertz up to gigahertz and u

Destroying superfluidity is a fundamental process and in fermionic superfluid such as He3-B it splits Cooper pairs into thermal excitations, quasiparticles. At the lowest temperatures, a gas of these quasiparticle excitations is tenuous enough for th

Superfluid 3He-B in the zero-temperature limit offers a unique means of studying quantum turbulence by the Andreev reflection of quasiparticle excitations by the vortex flow fields. We validate the experimental visualization of turbulence in 3He-B by

In this paper we discuss some (and only a small fraction) of the interesting properties of superfluid 3He at the low-temperature limit. We concentrate on the unique behavior and applications of the very dilute excitation gas at the lowest temperature

When immersed in liquid 3He, the nanometer strands of aerogel are coated with a thin layer of solid 3He, forming a network of irregular nanotubes. Owing to its high purity and weak interactions, this system is ideal for studying fundamental processes
