Search for the origin of zero-energy modes in topological materials – seminar


The Environmental Seminar on Solid State Physics as well as Seminar of the AGH UST Academic Centre for Materials and Nanotechnologies will be held on 12th December 2018, at 9.00 am.

A lecture titled “Search for the origin of zero-energy modes in topological materials” will be given by profesor from Institute of Physics Polish Academy of Sciences in Warsaw.

Venue: Academic Centre for Materials and Nanotechnology AGH UST (Kawiory 30 Street, building D-16, auditorium room 1.02A) 

An abstract of the lecture 

As an introduction, I will show how relativistic effects in quantum materials science lead to inverted band structures and topological phases in a broad classes of semiconductors. As a specific example of festinating new physics, I will discuss point-contact spectroscopy of several topological materials, which reveals a phase transition to a low temperature phase that is characterized by zero-energy modes superimposed on an energy gap showing a Bardeen-Cooper-Schrieffer-type of criticality. An experimental and theoretical search for the origin of this striking behavior in diamagnetic, paramagnetic, and ferromagnetic topological crystalline insulators will be presented.
