ICFO Seminar with Mariuz Gajda


I will show yet another, until quite recently undiscovered, consequence of quantum indistinguishability: identical fermions confined by an external trapping potential arrange themselves in spectacular geometric structures although no mutual interaction is present. These high order correlations, purely quantum in their nature, are a direct consequence of Pauli exclusion principle.

In the first part of my talk I will describe a theoretical methods of analysis of high order quantum correlations which are responsible for appearance of these crystalline structures. Then I will show how to identify the geometric arrangement of atoms from a series of single shot images of a quantum system, and describe the experiment of Heidelberg group reporting on the first observation of Pauli crystals.
