On an irregular basis various Special Seminars take place at the MPQ. The seminars are organized by scientists of our divisions, administration or staff representatives. The location will be announced with the event.
Host: MPQ, Theory Division

Non-symmorphic route to nodal semimetals (Tomas Bzdusek)

Nodal semimetals are materials in which the conduction and the valence bands touch at points or lines in the Brillouin zone. Such nodal band structures manifest themselves in unusual transport phenomena as well as in topologically protected surface states. ... [more]

Understanding Contextuality as a Quantum Computational Resource without Wigner Functions (Dr. J. Bermejo-Vega)

A central question in quantum computation is to identify the resources that are responsible for quantum speed-up. Quantum contextuality has been recently shown to be a resource for quantum computation with magic states for odd-prime dimensional qudits and two-dimensional systems with real wavefunctions. ...

Tests of quantumness are experiments which enable us to exclude the possibility of modeling them with classical means. They enable us to prove strong statements about the nature of the universe and obtain cryptographic protocols with an unprecedented level of security. [more]
Trapping ultracold atoms in optical lattices enabled numerous breakthroughs uniting several disciplines. Although light is a key ingredient in such systems, its quantum properties are typically neglected, reducing its role to a classical tool for atom manipulation. [more]
I will discuss two research lines I'm developing. [more]
