Behavior of vortices near twin boundaries in underdoped
B. Kalisky, J. R. Kirtley, J. G. Analytis +3
We use scanning SQUID microscopy to investigate the behavior of vortices in the presence of twin boundaries in the pnictide superconductor Ba(Fe1-xCox)2As2. We show that the vortic…
Pinpointing Gap Minima in Ba(FeCoAs \textit{via} Band Structure Calculations and Electronic Raman Scattering
I. I. Mazin, T. P. Devereaux, J. G. Analytis +4
A detailed knowledge of the gap structure for the Fe-pnictide superconductors is still rather rudimentary, with several conflicting reports of either nodes, deep gap minima, or ful…
Terahertz Kerr and Reflectivity Measurements on the Topological Insulator Bi2Se3
G. S. Jenkins, A. B. Sushkov, D. C. Schmadel +4
We report the first terahertz Kerr measurements on bulk crystals of the topological insulator Bi2Se3. At T=10K and fields up to 8T, the real and imaginary Kerr angle and reflectanc…
Two-dimensional Dirac fermions in a topological insulator: transport in the quantum limit
J. G. Analytis, R. D. McDonald, S. C. Riggs +3
Pulsed magnetic fields of up to 55T are used to investigate the transport properties of the topological insulator Bi_2Se_3 in the extreme quantum limit. For samples with a bulk car…
Bulk Fermi surface coexistence with Dirac surface state in BiSe: a comparison of photoemission and Shubnikov-de Haas measurements
James G. Analytis, Jiun-Haw Chu, Yulin Chen +4
Shubnikov de Haas (SdH) oscillations and Angle Resolved PhotoEmission Spectroscopy (ARPES) are used to probe the Fermi surface of single crystals of Bi2Se3. We find that SdH and AR…
