Yi Zhang,Tay-Rong Chang,Bo Zhou,Yong-Tao Cui,Hao Yan,Hao Yan,Zhongkai Liu,Zhongkai Liu,F. Schmitt,F. Schmitt,James J. Lee,James J. Lee,Robert G. Moore,Robert G. Moore,Yulin Chen,Yulin Chen,Yulin Chen,Hsin Lin,Horng-Tay Jeng,Sung-Kwan Mo,Zahid Hussain,Arun Bansil,Zhi-Xun Shen,Zhi-Xun Shen +23 more
TL;DR: The first direct observation of the transition from indirect to direct bandgap in monolayer samples is reported by using angle-resolved photoemission spectroscopy on high-quality thin films of MoSe2 with variable thickness, grown by molecular beam epitaxy.

TL;DR: The detailed angle-resolved photoemission measurements, first-principles simulations and theoretical topological analysis illustrate the physical mechanism underlying the formation of the topological nodal-line states and associated surface states for the first time, thus paving the way towards exploring the exotic properties of the bottom-line fermions in condensed matter systems.

TL;DR: Signs of the Weyl fermion chiral anomaly in the magneto-transport of TaAs are reported and it is observed that high mobility TaAs samples become more conductive as a magnetic field is applied along the direction of the current for certain ranges of the field strength.
