Jan Kycia


Jan Kycia’s group works on the experimental investigation of quantum mechanical properties of sub-micron and micron scaled superconducting devices. In particular Superconducting Single Electron Transistors (S-SETs) and Superconducting Quantum Interference Devices (SQUIDs). Attention is focused on gaining a better understanding of how dissipation and the environment affect the states of the devices. The group is also studying the 1/f noise in Josephson junctions. This 1/f noise may be an intrinsic limitation to the coherence time of superconducting devices for quantum computation.

The group is also studying numerous condensed matter systems including magnetic materials and heavy fermion superconductors. Specifically, we have focused on disordered and geometrically frustrated magnetic systems which may manifest exotic ground states such as spin glasses, spin ice and spin liquids. Our main characterization techniques are specific heat measurements and SQUID based magnetization and ac susceptibility.
