Martin Zemlicka
Superconducting Circuits

Martin studied physics at the Comenius University in Bratislava, Slovakia. During his master’s degree, he won the first place in Czech-Slovak Student Scientific International Conference in the field of applied physics, and defended his diploma thesis titled ‘Measurement and numerical analysis of superconducting coplanar resonators’. Following graduation, he started his PhD study as a part of Prof. Grajcar’s group and as a co-investigator of the European IQIT (Integrated Quantum Information Technology) project. He earned his PhD in 2016 with the dissertation thesis ‘Physical phenomena in disordered superconductors’ in which he analyzed prospective materials for superconducting nanotechnology applications. He received a postdoctoral fellowship from the Slovak academic information agency (SAIA) to work at IST Austria in the summer of 2017. Email: martin.zemlicka@ist.ac.at

PhD Students

Farid Hassani Bijarboonehimg_20170316_153553.jpg
Superconducting Circuits

Farid graduated with a master of electrical engineering from K. N. Toosi University of Technology in Tehran under the supervision of Dr. Farshid Raissi. In his master thesis he investigated the exponential behavior of the I-V curve in high Tc superconductors by introducing a new mechanism for vortices and anti-vortices, which was published in Applied Physics Letters in June 2014. After graduation, he joined Dr.Raissi’s team to work on fabrication of superconducting circuits based on Nb/AlOx/Nb Josephson junctions technology. Farid joined IST as a PhD student in September 2017.
