Dynamic competition between phason and amplitudon observed by ultrafast multimodal scanning tunneling microscopy
Seokjin Bae, Arjun Raghavan, Soyeun Kim +7
The intertwining between two ordered states that arise from the same interactions is reflected in the dynamics of their coupled collective excitations. While the equilibrium phase…
Strong Chirality Suppression in 1-D correlated Weyl Semimetal (TaSe4)2I
Utkarsh Khandelwal, Harshvardhan Jog, Shupeng Xu +6
The interaction of light with correlated Weyl semimetals (WSMs) provides a unique platform for exploring non-equilibrium phases and fundamental properties such as chirality. Here,…
Magnetic anisotropy in single-crystalline antiferromagnetic MnAu
Mebatsion S. Gebre, Rebecca K. Banner, Kisung Kang +4
Multiple recent studies have identified the metallic antiferromagnet MnAu to be a candidate for spintronic applications due to apparent in-plane anisotropy, preserved magnetic…
Electric quadrupole second harmonic generation revealing dual magnetic orders in a magnetic Weyl semimetal
Youngjun Ahn, Xiaoyu Guo, Rui Xue +4
Broken symmetries and electronic topology are nicely manifested together in the second order nonlinear optical responses from topologically nontrivial materials. While second order…
Disorder and diffuse scattering in single-chirality (TaSe)I crystals
Jacob A. Christensen, Simon Bettler, Kejian Qu +11
The quasi-one-dimensional chiral compound (TaSe)I has been extensively studied as a prime example of a topological Weyl semimetal. Upon crossing its phase transition temper…
Observation of the massive Lee-Fukuyama phason in a charge density wave insulator
Soyeun Kim, Yinchuan Lv, Xiao-Qi Sun +10
The lowest-lying fundamental excitation of an incommensurate charge density wave (CDW) material is widely believed to be a massless phason -- a collective modulation of the phase o…
A new quasi-one-dimensional transition metal chalcogenide semiconductor (NbSeI)I
Kejian Qu, Zachary W. Riedel, Irián Sánchez-Ramírez +8
The discovery of new low-dimensional transition metal chalcogenides is contributing to the already prosperous family of these materials. In this study, needle-shaped single crystal…
Ultrafast x-ray scattering reveals composite amplitude collective mode in the Weyl charge density wave material (TaSe)I
Quynh L. Nguyen, Ryan A. Duncan, Gal Orenstein +27
We report ultrafast x-ray scattering experiments of the quasi-1D charge density wave (CDW) material (TaSe)I following photoexcitation with femtosecond infrared laser pulses…
