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…

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…

Fermi level tuning and band alignment in Mn doped InAs/GaSb

Logan Riney, Joaquin Bermejo-Ortiz, Gauthier Krizman +10

InAs/GaSb hosts a broken gap band alignment that has been shown to generate helical topological edge states. Upon the introduction of Mn into the structure, it has been predicted t…
