Field-controlled breaking and restoration of parity-time symmetry in Josephson interference
Yi-Chen Tsai, Yung-Yeh Chang, Tao-Yi Hsu +6
Symmetry plays a fundamental role in determining the phases and physical properties of quantum matter. Controlling symmetry in mesoscopic superconducting devices provides a route t…

Magnetotransport evidence of a potential low-lying Dirac node in NbAl
Ying Kit Tsui, Chia-Nung Kuo, Makoto Shimizu +5
NbAl is a novel semimetal with a type-II Dirac node ~230 meV above the Fermi energy. We have performed both out-of-plane () and in-plane magnetotransport measurem…

Surface Second Harmonic Generation from Topological Dirac Semimetal PdTe
Syed Mohammed Faizanuddin, Ching-Hang Chien, Yao-Jui Chan +4
Recent experiments and calculations in topological semimetals have observed anomalously strong second-order optical nonlinearity, but yet whether the enhancement also occurs at sur…
