Non-equilibrium States and Interactions in the Topological Insulator and Topological Crystalline Insulator Phases of NaCd4As3
Tika R Kafle, Yingchao Zhang, Yi-yan Wang +12
Topological materials are of great interest because they can support metallic edge or surface states that are robust against perturbations, with the potential for technological app…
Relativistic ultrafast electron diffraction at high repetition rates
K. M. Siddiqui, D. B. Durham, F. Cropp +17
The ability to resolve the dynamics of matter on its native temporal and spatial scales constitutes a key challenge and convergent theme across chemistry, biology, and materials sc…
Bipolaronic nature of the pseudogap in (TaSe4)2I revealed via weak photoexcitation
Yingchao Zhang, Tika Kafle, Wenjing You +12
The origin of the pseudogap in many strongly correlated materials has been a longstanding puzzle. Here, we uncover which many-body interactions underlie the pseudogap in quasi-one-…
Creation of a novel inverted charge density wave state
Yingchao Zhang, Xun Shi, Mengxue Guan +10
Charge density wave (CDW) order is an emergent quantum phase that is characterized by a periodic lattice distortion and charge density modulation, often present near superconductin…
Coherent modulation of the electron temperature and electron-phonon couplings in a 2D material
Yingchao Zhang, Xun Shi, Wenjing You +9
Ultrashort light pulses can selectively excite charges, spins and phonons in materials, providing a powerful approach for manipulating their properties. Here we use femtosecond las…
Ultrafast electron calorimetry uncovers a new long-lived metastable state in 1T-TaSe mediated by mode-selective electron-phonon coupling
Xun Shi, Wenjing You, Yingchao Zhang +8
Quantum materials represent one of the most promising frontiers in the quest for faster, lightweight, energy efficient technologies. However, their inherent complexity and rich pha…
Revealing the nature of the ultrafast magnetic phase transition in Ni by correlating extreme ultraviolet magneto-optic and photoemission spectroscopies
Wenjing You, Phoebe Tengdin, Cong Chen +10
By correlating time- and angle-resolved photoemission and time-resolved transverse- magneto- optical Kerr effect measurements, both at extreme ultraviolet wavelengths, we uncover t…
