Electronic and structural fingerprints of charge density wave excitations in extreme ultraviolet transient absorption spectroscopy
Tobias Heinrich, Hung-Tzu Chang, Sergey Zayko +3
Femtosecond core-level transient absorption spectroscopy is utilized to investigate photoinduced dynamics of the charge density wave in 1T-TiSe2 at the Ti M2,3 edge (30-50 eV). Pho…
On the survival of Floquet-Bloch states in the presence of scattering
S. Aeschlimann, S. A. Sato, R. Krause +9
Floquet theory has spawned many exciting possibilities for electronic structure control with light with enormous potential for future applications. The experimental realization in…
Phonon collapse and van der Waals melting of the 3D charge density wave of VSe
Josu Diego, A. H. Said, S. K. Mahatha +7
Among transition metal dichalcogenides (TMDs), VSe is considered to develop a purely 3-dimensional (3D) charge-density wave (CDW) at T=110 K. Here, by means of high res…
Larger than 80% Valley Polarization of Free Carriers in Singly-Oriented Single Layer WS on Au(111)
H. Beyer, G. Rohde, A. Grubišić Čabo +10
We employ time- and angle-resolved photoemission spectroscopy to study the spin- and valley-selective photoexcitation and dynamics of free carriers at the K and K' points in singly…
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…
