Magneto-optical evidence of tilting effect in coupled Weyl bands
Seongphill Moon, Yuxuan Jiang, Jennifer Neu +4
Theories have revealed the universality of the band tilting effect in topological Weyl semimetals (WSMs) and its implications for the material's physical properties. However, the e…
Revealing temperature evolution of the Dirac band in ZrTe via magneto-infrared spectroscopy
Yuxuan Jiang, Tianhao Zhao, Luojia Zhang +5
We report the temperature evolution of the Dirac band in semiconducting zirconium pentatelluride (ZrTe) using magneto-infrared spectroscopy. We find that the band gap is temper…
Landau quantization in tilted Weyl semimetals with broken symmetry
Luojia Zhang, Yuxuan Jiang, Dmitry Smirnov +1
Broken symmetry and tilting effects are ubiquitous in Weyl semimetals (WSMs). Therefore, it is crucial to understand their impacts on the materials' electronic and optical properti…
Dirac energy spectrum and inverted band gap in metamorphic InAsSb/InSb superlattices
Sergey Suchalkin, Maksim Ermolaev, Tonica Valla +9
A Dirac-type energy spectrum was demonstrated in gapless ultra-short-period metamorphic InAsSb/InSb superlattices by angle-resolved photoemission spectroscopy (ARPES_ measurements.…
Landau quantization in coupled Weyl points: a case study of semimetal NbP
Y. Jiang, Z. L. Dun, S. Moon +4
Weyl semimetal (WSM) is a newly discovered quantum phase of matter that exhibits topologically protected states characterized by two separated Weyl points with linear dispersion in…
Metamorphic InAs1-xSbx/InAs1-ySby superlattices with ultra-low bandgap as a Dirac material
Sergey Suchalkin, Gregory Belenky, Maksim Ermolaev +9
It was experimentally demonstrated that short-period metamorphic InAs1-xSbx/InAs1-ySby superlattices with ultra low bandgap have properties of a Dirac material. Cyclotron resonance…
Evidence for an excitonic insulator phase in a zero-gap InAs/GaSb bilayer
W. Yu, V. Clericò, C. Hernández Fuentevilla +16
Many-body interactions can produce novel ground states in a condensed-matter system. For example, interacting electrons and holes can spontaneously form excitons, a neutral bound s…
