Welcome to the Allan Lab

We are a dynamic research group at the Leiden Institute of Physics. Our aim is to explore and understand quantum materials, including strange metals, high-temperature superconductors, and quantum critical electron matter.

To this end, we develop novel spectroscopic-imaging scanning tunneling microscopy (SI-STM) tools to visualize the relevant quantum mechanical degrees of freedom. We want to be able to build the perfect instruments to answer the scientific questions we deem most important (see Research).

We are located at Leiden University, the birthplace of superconductivity and home to Kamerlingh Onnes, Lorentz, Huygens, Einstein, de Sitter, and others (see e.g. the wall of signatures from Ehrenfest lecturers). We exchange ideas and work with our neighbors from Quantum Matter & Optics, as well as with the colleagues from our world-class theory section.

We are looking for passionate new PhD students, Postdocs, and Master students to join the team (more info) !

We are grateful for funding from Leiden University, NWO (Vidi talent scheme and the Frontiers in Nanoscience program), and from an ERC starting grant.
