Welcome to the University of Jyväskylä physics colloquium. 

On Friday 10th May at 10 am in FYS1 and Zoom [https://jyufi.zoom.us/j/66703175507] (passcode 890524):
Mika Prunnila (VTT):
On-chip electron refrigeration for quantum technology
Numerous applications, from industrial non-destructive imaging through ultra-sensitive photon counting to various implementations of solid-state quantum computers require low temperatures for their sensor and processor chips. Replacing the bulky cryo-liquid based cooling stages of cryo-enabled instruments by chip scale refrigeration is envisioned to disruptively reduce the system size similarly as microprocessors did for computers. Chip scale cooling has been demonstrated with electronic refrigerators based on tunnel junctions in the sub-1 K temperature range, and just recently also above 2 K. In this colloquium I will discuss physics and recent approaches of chip scale refrigeration.
Welcome!
Coffee will be served in the lobby. Although on-site attendance is the preferred option, you can also join via Zoom. Please do not send chat messages in Zoom during the talk, except if you need to tell about a muted speaker.

Confirmed colloquium talks in the Spring 2024 (you are welcome to suggest more - there are still a couple of open slots in May):
5.6. (Wednesday!) Arttu Rajantie (London): TBA
18.6. Toshimi Suda (Tohoku): What do unstable atomic nuclei look like? (tentative)
