Possibility of the direct detection of Dark Matter particles with the help of liquid helium

The modern state of the Dark Matter (DM) problem is briefly considered. A scheme of direct detection of DM particles with the help of liquid helium is proposed. The energy sensitivity of the detector based on this scheme is estimated.

Ordinary SQUID interferometers and superfluid helium matter wave interferometers: The role of quantum fluctuations

When comparing the operation of a superfluid helium matter wave quantum interferometer (He SQUID) with that of an ordinary direct-current quantum interferometer (dc SQUID), we estimate their resolution limitation that correspond to quantum fluctuations. An alternative mode of operation of the interferometer as a unified macroquantum system is considered.

Scheme of laboratory measurements of gravimagnetic effects with SHeQUID equipped with a rotation flux transformer

We suggest a scheme of the Superfluid Helium Quantum Interference Device (SHeQUID) with a transformer of the angular momentum stream, whose working medium is superfluid liquid He4. A scheme is provided for measuring the Lense-Thirring effect under laboratory conditions as well as other effects related to super slow rotations.
