Active spintronic-metasurface terahertz emitters with tunable chirality
Changqin Liu, Sheng Zhang, Shunjia Wang +6
The ability to manipulate the electric-field vector of broadband terahertz waves is essential for applications of terahertz technologies in many areas, and can open up new possibil…
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…
A brief review: Ultrafast electron diffractive voltammetry: General formalism and applications
Kiseok Chang, Ryan A. Murdick, Zhensheng Tao +2
We present a general formalism of ultrafast diffractive voltammetry approach as a contact-free tool to investigate the ultrafast surface charge dynamics in nanostructured interface…
Ultrafast imaging of photoelectron packets generated from graphite surface
Ramani K. Raman, Zhensheng Tao, Tzong-Ru Han +1
We present an electron projection imaging method to study the ultrafast evolution of photoelectron density distribution and transient fields near the surface. The dynamical profile…
