Colossal magnetoresistance in a nonsymmorphic antiferromagnetic insulator
P. F. S. Rosa, Yuanfeng Xu, S. K. Kushwaha +14
Here we investigate antiferromagnetic EuInSb, a nonsymmorphic Zintl phase. Our electrical transport data show that EuInSb is remarkably insulati…
Magnetic field-tuned quantum criticality in a Kondo insulator
Satya K. Kushwaha, Mun K. Chan, Joonbum Park +6
Kondo insulators are predicted to undergo an insulator-to-metal transition under applied magnetic field, yet the extremely high fields required to date have prohibited a comprehens…
A gap-protected zero-Hall effect state in the quantum limit of the nonsymmorphic metal KHgSb
Sihang Liang, Satya Kushwaha, Tong Gao +8
A recurring theme in topological matter is the protection of unusual electronic states by symmetry, for example, protection of the surface states in Z2 topological insulators by ti…
Role of matrix elements in the time-resolved photoemission signal
F. Boschini, D. Bugini, M. Zonno +17
Time- and angle-resolved photoemission spectroscopy accesses the ultrafast evolution of quasiparticles and many-body interactions in solid-state systems. However, the momentum- and…
Universal superconductivity phase diagram for pressurized tetradymite topological insulators
Shu Cai, S. K. Kushwaha, Jing Guo +13
We show that two different superconducting phases exist at high pressures in the optimized tetradymite topological insulators Bi2Te2Se (BTS) and Bi1.1Sb0.9Te2S (BSTS). The supercon…
Independence of topological surface state and bulk conductances in three-dimensional topological insulators
Shu Cai, Jing Guo, Vladimir A. Sidorov +12
The archetypical 3D topological insulators Bi2Se3, Bi2Te3 and Sb2Te3 commonly exhibit high bulk conductivities, hindering the characterization of the surface state charge transport…
