Trion gas on the surface of a failed excitonic insulator
Yuval Nitzav, Abigail Dishi, Himanshu Lohani +15
Trions, three-body bound states composed of an exciton and an additional charge, are typically fragile and require external excitation to form. Here, we report the spontaneous emer…
Quantifying quasiparticle chirality in a chiral topological semimetal
Jiaju Wang, Jaime Sánchez-Barriga, Amit Kumar +17
Recently, the projection of the electron's spin on its crystal momentum has been proposed as a metric to quantify electronic chirality of Bloch states in crystals, which is expecte…
Spin Texture Control and Magnetic Gap Engineering in a Ferromagnetic Insulator-Topological Insulator Sandwiched Heterostructure
Mohammad T. H. Bhuiyan, Qile Li, James Blyth +10
Quantum materials combining magnetism and topological fermions are a key platform for low-energy electronics, spintronics, and quantum phases that break time-reversal symmetry (TRS…
Nodeless Hybridization as Proof of Trivial Topology in Samarium Hexaboride
E. D. L. Rienks, P. Hlawenka, J. Sánchez-Barriga +13
Calculations unanimously predict samarium hexaboride to be a topological Kondo insulator, the first topological insulator driven by strong electron correlation. As of today it appe…
TruthLens:A Training-Free Paradigm for DeepFake Detection
Ritabrata Chakraborty, Rajatsubhra Chakraborty, Ali Khaleghi Rahimian +1
The proliferation of synthetic images generated by advanced AI models poses significant challenges in identifying and understanding manipulated visual content. Current fake image d…
Prediction and observation of the first antiferromagnetic topological insulator
Mikhail M. Otrokov, Ilya I. Klimovskikh, Hendrik Bentmann +41
Magnetic topological insulators (MTIs) are narrow gap semiconductor materials that combine non-trivial band topology and magnetic order. Unlike their nonmagnetic counterparts, MTIs…
