Topological Fermi-arc surface resonances in bcc iron
Daniel Gosálbez-Martínez, Gabriel Autès, Oleg V. Yazyev
The topological classification of matter has been extended to include semimetallic phases characterized by the presence of topologically protected band degeneracies. In Weyl semime…
Identifying substitutional oxygen as a prolific point defect in monolayer transition metal dichalcogenides with experiment and theory
Sara Barja, Sivan Refaely-Abramson, Bruno Schuler +17
Chalcogen vacancies are considered to be the most abundant point defects in two-dimensional (2D) transition-metal dichalcogenide (TMD) semiconductors, and predicted to result in de…
Magnetoresistance from Fermi Surface Topology
Sheng Nan Zhang, Quan Sheng Wu, Yi Liu +1
Extremely large non-saturating magnetoresistance has recently been reported for a large number of both topologically trivial and non-trivial materials. Different mechanisms have be…
Plethora of Coexisting Topological Band Degeneracies in Nonsymmorphic Molecular Crystal OsOF
Hyungjun Lee, Oleg V. Yazyev
In band theory of solids, degeneracies manifest themselves as point, line, and surface objects. The topological nature of band degeneracies has recently been appreciated since the…
Observation of a nodal chain with Dirac surface states in TiB2
C. -J. Yi, B. Q. Lv, Q. S. Wu +13
Topological nodal-line semimetals (TNLSMs) are characterized by symmetry-protected band crossings extending along one-dimensional lines in momentum space. The nodal lines exhibit a…
MgTa2N3: A new reference Dirac semimetal
QuanSheng Wu, Christophe Piveteau, Zhida Song +1
We present a prediction of the Dirac semimetal (DSM) phase in MgTa2N3 based on first-principles calculations and symmetry analysis. In this material, the Fermi level is located exa…
Trivial topological phase of CaAgP and the topological nodal-line transition in CaAg(P1-xAsx)
N. Xu, Y. T. Qian, Q. S. Wu +14
By performing angle-resolved photoemission spectroscopy and first-principles calculations, we address the topological phase of CaAgP and investigate the topological phase transitio…
Single-layer -MoS under electron irradiation from molecular dynamics
Michele Pizzochero, Oleg V. Yazyev
Irradiation with high-energy particles has recently emerged as an effective tool for tailoring the properties of two-dimensional transition metal dichalcogenides. In order to carry…
Point defects in the 1 and 2 phases of single-layer MoS: A comparative first-principles study
Michele Pizzochero, Oleg V. Yazyev
The metastable 1 phase of layered transition metal dichalcogenides has recently attracted considerable interest due to electronic properties, possible topological electronic ph…
Condensed matter realization of fermion quasiparticles in Minkowski space
Xiao Dong, QuanSheng Wu, Oleg V. Yazyev +4
"What is the difference between space and time?" is an ancient question that remains a matter of intense debate. In Newtonian mechanics time is absolute, while in Einstein's theory…
Observation of Topologically Protected States at Crystalline Phase Boundaries in Single-layer WSe2
Miguel M. Ugeda, Artem Pulkin, Shujie Tang +12
Transition metal dichalcogenide (TMD) materials are unique in the wide variety of structural and electronic phases they exhibit in the two-dimensional (2D) single-layer limit. Here…
