DESCRIPTION:Speaker: Giacomo Trupiano\nhosted by Georgios Katsaros\nAbstrac
 t: Magnetic fields are a familiar way to control superconducting circuits\
 , but they are not the only possibility. Heat and applied voltages can als
 o change how these devices carry current\, offering new opportunities for 
 superconducting electronics.In this seminar\, I will discuss these possibi
 lities through theoretical models and experiments. I will introduce concep
 ts for controlling superconducting circuits by injecting electronic excita
 tions\, and present the experimental realization of a superconducting volt
 age amplifier powered by a temperature difference. I will then turn to vol
 tage-controlled devices: semiconductor junctions in which a gate tunes sup
 erconducting current\, and a fully suspended metallic superconducting nano
 wire in which a gate voltage strongly modifies the rate of switching into 
 a resistive state.Together\, these results show how the sensitivity of sup
 erconducting devices to heat and voltage can be used to amplify electrical
  signals\, tune current transport\, and control switching dynamics.On a se
 parate note\, I am also planning to join Prof. Katsaros's group as a postd
 octoral researcher. Although the arrangements are not yet formally finaliz
 ed\, I have started looking into accommodation options from February 2027.
  I was wondering whether ISTA housing might be available from that time\, 
 and if you could point me towards the appropriate person to contact about 
 availability and the application procedure.
