- 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.

- Rotational symmetry breaking in topological superconductor
Our group, in collaboration with the Institute for Materials Science in Tsukuba (Japan), has discovered an exceptional new quantum state within a superconducting material. This exceptional quantum state is characterised by a broken rotational symmetry – in other words, if you turn the material in a magnetic field, the superconductivity isn't the same everywhere in the material.

- Knobs control Dirac energy in topological insulators
Four knobs - bulk stoichiometry, surface decoration, temperature, and photon exposure - are shown to control the energy of Dirac surface states in topological insulators, and can be used to determine the true 'flat band' energy band alignment at the surface of binary, ternary or quaternary 3D TI's.
