COLLOQUIUM
Institute of Physics Polish Academy of Sciences
 
 


The formal colloquium of the Institute of Physics, Polish Academy of Sciences it the main ongoing periodic series of lectures in physics and related science, of interest to members of the Institute. It is held from 1977. Colloquium speakers are primarily domestic and foreign scholars of established reputation, but also less-known physicists with remarkable and current scientific achievements. The colloquium is held once a month from September to June, usually at 3:15 PM on the last Tuesday of the month in the Auditorium of the Institute of Physics. Colloquia are open to the public, and are preceded by a coffee/the reception at the Institute.

For future information about the colloquia, pleace contact Prof. Dr. hab. Leszek Sirko (sirko@ifpan.edu.pl), current chairman of the colloquium committee.

Abstract


      Two-dimensional superconductors with broken time-reversal symmetry have been predicted to support topologically protected chiral edge states, providing a superconducting counterpart to the quantum Hall effect in semiconductors. The edge states carry charge-neutral quasiparticles, coherent superpositions of electrons and holes referred to as "Majorana fermions". The first observations have been reported recently, after several decades of unsuccesful search. We present an overview of electrical and thermal probes of the superconducting edge states, focusing on unique signatures of their Majorana nature and on applications for topological quantum computation.
