Welcome to the website of Dr. A. de Visser. I am member of the Hard Condensed Matter group at the Van der Waals-Zeeman Institute for Experimental Physics, which is part of the Institute of Physics of the Faculty of Science, University of Amsterdam. My research field is Quantum Electron Matter, with a focus on strongly correlated electron phenomena, notably quantum criticality and unconventional superconductivity, and topological insulators. On this site you will find a brief description of research projects, an outline of experimental facilities, group members and scientific output. Recent publications and theses are available as pdf files.

PhD position in Nematic superconductivity in topological materials

A PhD position is available in the Quantum Matter Amsterdam Group of the WZI at the University of Amsterdam. The project focuses on new family of superconductors that is obtained by doping a topological insulator: Bi2Se3-based superconductors. We will explore a recent experimental discovery, namely rotational symmetry breaking in the macroscopic superconducting parameters.
