Experimental Condensed Matter Physics

The Experimental Condensed Matter Physics Group at Stockholm University was started in February 2005. Research in the group is focused at the study of mesoscopic phenomena in condensed matter physics. Our research areas span over superconductivity (with emphasis on high temperature superconductors), low temperature physics, quantum electronics and spintronics, and nanotechnology.

Specifically, current research topics are: intrinsic tunneling spectroscopy of high temperature superconductors, THz applications of superconducting tunnel (Josephson) junctions, analysis of non-equilibrium effects in stacked Josephson junctions, study of hybrid superconductor/ferromagnet devices for spintronic applications and development of ultrasensitive nanocalorimetry methods. More details are given under the headers Research and Publications.

Methodology and experimental techniques

We make our samples using advanced sample engineering and micro/nano-fabrication in clean-room environment. The major part of the sample fabrication is made at the Nano-Fab Lab, a joint facility between KTH and Stockholm University, located here at AlbaNova University Center.

We also have a cryogen-free, low-temperature lab, containing various low-temperature, high magnetic field, and measurement equipment. The equipment is completed with high-frequency instrumentation and an optical cryostat. For more details see Experimental facilities.

Open access to the low-temperature lab (! NEW ! November 2014)

The low temperature lab is open for use under the following conditions: Cryostates and measurement equipment: 1000 SEK/day for internal and 3000 SEK/day for external users. The cost of assisting technician 700 SEK/hour, researcher 1000 SEK/hour. When appropriate, the equipment can be offered under a condition of mutual collaboration. Details of the access to the lab should be discussed with V. Krasnov.
