Spontaneous Breaking of the SU(3) Flavor Symmetry in a Quantum Hall Valley Nematic
G. Krizman, A. Kazakov, C. -W. Cho +10
Two-dimensional quantum materials can host original electronic phases that arise from the interplay of electronic correlations, symmetry and topology. In particular, the spontaneou…
Valley-Polarized quantum Hall phase in a strain-controlled Dirac system
G. Krizman, J. Bermejo-Ortiz, T. Zakusylo +9
In multivalley systems, the valley pseudospin offers rich physics going from encoding of information by its polarization (valleytronics), to exploring novel phases of matter when i…
3D Topological Semimetal Phases of Strained -Sn on Insulating Substrate
Jakub Polaczyński, Gauthier Krizman, Alexandr Kazakov +15
-Sn is an elemental topological material, whose topological phases can be tuned by strain and magnetic field. Such tunability offers a substantial potential for topological elec…
Enhanced Dirac node separation in strained Cd3As2 topological semimetal
Gauthier Krizman, Joaquin Bermejo-Ortiz, Manik Goyal +7
In topological semimetals, nodes appear at symmetry points in the Brillouin zone as a result of band inversion, and yield quasi-relativistic massless fermions at low energies. Cd3A…
Observation of Weyl and Dirac fermions at smooth topological Volkov-Pankratov heterojunctions
J. Bermejo-Ortiz, G. Krizman, R. Jakiela +6
Weyl and Dirac relativistic fermions are ubiquitous in topological matter. Their relativistic character enables high energy physics phenomena like the chiral anomaly to occur in so…
Energy gap of topological surface states in proximity to a magnetic insulator
Jiashu Wang, Tianyi Wang, Mykhaylo Ozerov +14
Topological surface-states can acquire an energy gap when time-reversal symmetry is broken by interfacing with a magnetic insulator. This gap has yet to be measured. Such topologic…
