Signatures of ultrafast reversal of excitonic order in TaNiSe
H. Ning, O. Mehio, M. Buchhold +4
In the presence of electron-phonon coupling, an excitonic insulator harbors two degenerate ground states described by an Ising-type order parameter. Starting from a microscopic Ham…
Quantum Hall Effect on Top and Bottom Surface States of Topological Insulator (Bi1-xSbx)2Te3 Films
R. Yoshimi, A. Tsukazaki, Y. Kozuka +6
The three-dimensional (3D) topological insulator (TI) is a novel state of matter as characterized by two-dimensional (2D) metallic Dirac states on its surface. Bi-based chalcogenid…
Trajectory of Anomalous Hall Effect toward the Quantized State in a Ferromagnetic Topological Insulator
J. G. Checkelsky, R. Yoshimi, A. Tsukazaki +5
Topological insulators are bulk electronic insulators which possess symmetry protected gapless modes on their surfaces. Breaking the symmetries that underlie the gapless nature of…
Bulk Band Gap and Surface State Conduction Observed in Voltage-Tuned Crystals of the Topological Insulator BiSe
J. G. Checkelsky, Y. S. Hor, R. J. Cava +1
We report a transport study of exfoliated few monolayer crystals of topological insulator BiSe in an electric field effect (EFE) geometry. By doping the bulk crystals with…
The development of ferromagnetism in the doped topological insulator Bi2-xMnxTe3
Y. S. Hor, P. Roushan, H. Beidenkopf +11
The development of ferromagnetism in Mn-doped Bi2Te3 is characterized through measurements on a series of single crystals with different Mn content. Scanning tunneling microscopy a…
Thermal Hall Conductivity as a Probe of Gap Structure in Multi-band Superconductors: The Case of
J. G. Checkelsky, R. Thomale, Lu Li +4
The sign and profile of the thermal Hall conductivity gives important insights into the gap structure of multi-band superconductors. With this perspective, we have investi…
