TL;DR: This work experimentally demonstrates an electronically-tunable terahertz intensity modulator based on Bi1:5Sb0:5Te1:8Se1:2 single crystal, one of the most insulating topological insulators, and proposes that the extraordinarily large modulation is a consequence of thermally-activated carrier absorption in the semiconducting bulk states.

TL;DR: Spatial imaging of current-induced spin accumulation at the edges of Bi2Se3 and BiSbTeSe2 topological insulators as well as Pt by a scanning photovoltage microscope at room temperature points towards a better understanding of the interaction between spins and circularly polarized light.

TL;DR: A novel, sufficient optimality condition that relies on a convex differencing representation of the penalized loss function and the subdifferential calculus is introduced that enables the oracle property for sparse quantile regression in the ultra-high dimension under relaxed conditions.

TL;DR: Anomalous Hall effect measurements on single crystalline metallic Fe3GeTe2 nanoflakes with different thicknesses are reported to highlight its potential for integration into van der Waals magnetic heterostructures, paving the way for spintronic research and applications based on these devices.

TL;DR: A new locally weighted censored quantile regression approach that adopts the redistribution-of-mass idea and employs a local reweighting scheme, and establishes the consistency and asymptotic normality of the proposed estimator.
