Superfluid flow above the critical velocity (2017)
Journal Article

Superfluidity and superconductivity have been widely studied since the last century in many different contexts ranging from nuclear matter to atomic quantum gases. The rigidity of these systems with respect to external perturbations results in fricti... Read More about Superfluid flow above the critical velocity.

Enhancing optoelectronic properties of SiC-grown graphene by a surface layer of colloidal quantum dots (2017)
Journal Article

We report a simultaneous increase of carrier concentration, mobility and photoresponsivity when SiC-grown graphene is decorated with a surface layer of colloidal PbS quantum dots, which act as electron donors. The charge on the ionised dots is spatia... Read More about Enhancing optoelectronic properties of SiC-grown graphene by a surface layer of colloidal quantum dots.

Microwave Generation in Synchronized Semiconductor Superlattices (2017)
Journal Article

We study high-frequency generation in a system of electromagnetically coupled semiconductor superlattices fabricated on the same doped substrate. Applying a bias voltage to a single superlattice generates high-frequency current oscillations. We demon... Read More about Microwave Generation in Synchronized Semiconductor Superlattices.

A new generation of magnetoencephalography: Room temperature measurements using optically-pumped magnetometers (2017)
Journal Article

© 2017 The Authors Advances in the field of quantum sensing mean that magnetic field sensors, operating at room temperature, are now able to achieve sensitivity similar to that of cryogenically cooled devices (SQUIDs). This means that room temperatur... Read More about A new generation of magnetoencephalography: Room temperature measurements using optically-pumped magnetometers.
