Gap-opening transition in Dirac semimetal ZrTe

Yefan Tian, Nader Ghassemi, Joseph H. Ross

We apply Te nuclear magnetic resonance (NMR) spectroscopy to investigate the Dirac semimetal ZrTe. With the NMR magnetic field parallel to the -axis, we observe sign…

Topological nodal line in ZrTe demonstrated by nuclear magnetic resonance

Yefan Tian, Nader Ghassemi, Joseph H. Ross

In this work, we report nuclear magnetic resonance (NMR) combined with density functional theory (DFT) studies of the transition metal dichalcogenide ZrTe. The measured NMR shi…

Copper ion dynamics and phase segregation in Cu-rich tetrahedrite: an NMR study

Nader Ghassemi, Yefan Tian, Xu Lu +3

Cu NMR measurements are reported for the Cu-rich phase of \ch{Cu_{12+x}Sb4S13} () and compared to \ch{Cu12Sb4S13}. We identify the NMR signatures of the phase…
