Journal ArticleDOI
Observation of Weyl nodes and Fermi arcs in tantalum phosphide
Nan Xu,Hongming Weng,B. Q. Lv,B. Q. Lv,Christian Matt,J. Park,Federico Bisti,Vladimir N. Strocov,Dariusz Jakub Gawryluk,Ekaterina Pomjakushina,Kazimierz Conder,Nicholas C. Plumb,Milan Radovic,Gabriel Autès,Oleg V. Yazyev,Zhong Fang,Xi Dai,Tianmei Qian,Joël Mesot,Joël Mesot,Joël Mesot,Hong Ding,Ming Shi +22 more
TL;DR: It is shown that TaP is a Weyl semimetal with only a single type of Weyl fermions, topologically distinguished from TaAs where two types of Weylefermions contribute to the low-energy physical properties.
Journal ArticleDOI
Synthesis and crystal growth of Cs 0.8 (FeSe 0.98 ) 2 :a new iron-based superconductor with T c = 27 K
Anna Krzton-Maziopa,Zurab Shermadini,Ekaterina Pomjakushina,Vladimir Pomjakushin,Markus Bendele,Markus Bendele,Anthony A. Amato,Rustem Khasanov,Hubertus Luetkens,Kazimierz Conder +9 more
TL;DR: The synthesis of large single crystals of a new FeSe layer superconductor Cs( 0.8)(FeSe(0.98))(2) is reported on, which shows a slightly lower superconducting transition temperature and the T(c) dependence on the anion height was found to be analogous to those reported for As-containing Fe superconductors and Fe(Se(1 - x)Ch(x)), where Ch = Te, S.
Journal ArticleDOI
Spin-state transition in LaCoO3: direct neutron spectroscopic evidence of excited magnetic states.
Andrey Podlesnyak,S. Streule,Joël Mesot,Marisa Medarde,Ekaterina Pomjakushina,Kazimierz Conder,Arata Tanaka,Maurits W. Haverkort,D. I. Khomskii +8 more
TL;DR: This work interprets an excitation in LaCoO3 as originating from a transition between thermally excited states located about 120 K above the ground state, and discusses the nature of the magnetic excited state in terms of intermediate-spin versus high-spin states.
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.
