Groups


Vladimir EltsovROTA

The research in the ROTA group is focused on the properties of superfluid 3He at ultra-low temperatures. The superfluid phases of 3He are the best experimentally accessible examples of topological superfluids, which share many properties with popular topological insulators and superconductors. We are interested in particular in emergent fermion zero modes, like Majorana fermions at the surfaces and in the cores of the topological defects of the order parameter. The dynamic behavior and interaction between the objects of different topologies are also investigated.

Juha TuoriniemiµKI

The µKI group focuses on systems thermally active still at microkelvin range of temperatures. This applies to most nuclear spin ensembles, fermion fluids (pure and dilute 3He), and some conduction electron systems, which fail to develop superconductivity or magnetic ordering at higher temperatures. Different subsystems of matter may have very different temperatures at the same time, though they may be spatially inseparable. Fascinating examples of this are the assemblies of nuclear spins and conduction electrons in metals.

The PICO group focuses on mesoscopic physics and its sensor applications. The main interest is on charge transport and thermal properties of metallic, superconducting and hybrid nanostructures. Particular research topics include electronic thermometry and refrigeration, nonequilibrium effects, Josephson devices, quantized and coherent charge pumping, noise, fluctuations and full counting statistics of charge and heat transport.

NEMS

The NEMS group focuses on studies of micro- and nanomechanical resonators near the quantum ground state of moving objects. In principle it is possible to prepare a nearly macroscopic body into a Schrödinger’s cat type of motional quantum state where the object resides in two places the same time. The group aims on measuring this exciting physics by coupling vibrating beams or graphene membranes to electrical circuits built upon superconducting junctions or resonators. The group also investigates quantum phenomena in such superconducting junction qubits.

QUANTUM TRANSPORT (QT)

The QT group works on theoretical problems in quantum transport. Central research topics include electronic transport in Coulomb-blockade quantum dots, dynamic single-electron sources as well as electrical noise and fluctuations in nano-scale conductors. The group is also interested in quantum correlations and entanglement in many-body systems and the statistical mechanics of small quantum devices.
