Journal ArticleDOI
Direct observation of the spin texture in SmB6 as evidence of the topological Kondo insulator
Nan Xu,Pabitra Kumar Biswas,Jan Hugo Dil,Rajendra S. Dhaka,Rajendra S. Dhaka,Gabriel Landolt,Stefan Muff,Stefan Muff,Christian Matt,X. Shi,Nicholas C. Plumb,Milan Radovic,Ekaterina Pomjakushina,Kazimierz Conder,Anthony A. Amato,Sergey Borisenko,Runze Yu,Hongming Weng,Zhen Fang,Xingchao Dai,Joël Mesot,Hong Ding,Ming Shi +22 more
TL;DR: These results provide strong evidence that SmB6 can host topological surface states in a bulk insulating gap stemming from the Kondo effect, which can serve as an ideal platform for investigating of the interplay between novel topological quantum states with emergent effects and competing orders induced by strongly correlated electrons.
Journal ArticleDOI
Importance of the Fermi-surface topology to the superconducting state of the electron-doped pnictide Ba(Fe1-xCox) 2As2
Chang Liu,Ari Palczewski,Rajendra S. Dhaka,Takeshi Kondo,Rafael M. Fernandes,E. D. Mun,Halyna Hodovanets,Alexander Thaler,Joerg Schmalian,S.L. Bud'ko,P. C. Canfield,Adam Kaminski +11 more
TL;DR: In this paper, angle-resolved photoemission spectroscopy and thermoelectric power were used to study the poorly explored, highly overdoped side of the phase diagram of Ba(Fe{}_{1\ensuremath{-}x}$Co${}_{x})${}{2}$As${}_1}$ high-temperature superconductor.
Journal ArticleDOI
Bimetallic Au-Cu alloy nanoparticles on reduced graphene oxide support: Synthesis, catalytic activity and investigation of synergistic effect by DFT analysis
TL;DR: In this article, high active and well defined Au-Cu nanoparticles supported on reduced graphene oxide (rGO) were synthesized by a simple and one-step deposition-precipitation method.
Journal ArticleDOI
Ba 1 − x K x Mn 2 As 2 : An Antiferromagnetic Local-Moment Metal
Abhishek Pandey,Rajendra S. Dhaka,Jagat Lamsal,Yongbin Lee,V. K. Anand,Andreas Kreyssig,Tom Heitmann,Robert J. McQueeney,Alan I. Goldman,B. N. Harmon,Adam Kaminski,David C. Johnston +11 more
TL;DR: Ba(1-x)K(x)Mn2As2 is thus the first metallic ThCr2Si2-type MAs-based system containing local 3d transition metal M magnetic moments, with consequences for the ongoing debate about the local-moment versus itinerant pictures of the FeAs- based superconductors and parent compounds.
Journal ArticleDOI
Greener Route for Synthesis of aryl and alkyl-14H-dibenzo [a.j] xanthenes using Graphene Oxide-Copper Ferrite Nanocomposite as a Recyclable Heterogeneous Catalyst.
TL;DR: The present approach offers several advantages such as short reaction times, high yields, easy purification, a cleaner reaction, ease of recovery and reusability of the catalyst by a magnetic field.
