Dirac parameters and topological phase diagram of Pb1-xSnxSe from magneto-spectroscopy
G. Krizman, B. A. Assaf, T. Phuphachong +4
Pb1-xSnxSe hosts 3D massive Dirac fermions across the entire composition range for which the crystal structure is cubic. In this work, we present a comprehensive experimental mappi…

Avoided level crossing at the magnetic field induced topological phase transition due to spin-orbital mixing
G. Krizman, B. A. Assaf, M. Orlita +7
In 3D topological insulators, an effective closure of the bulk energy gap with increasing magnetic field expected at a critical point can yield a band crossing at a gapless Dirac n…

Tunable Dirac interface states in topological superlattices
G. Krizman, B. A. Assaf, T. Phuphachong +6
Relativistic Dirac fermions are ubiquitous in condensed matter physics. Their mass is proportional to the material energy gap and the ability to control and tune the mass has becom…
