Structural Origin of Boson Peak in Glasses
Yuan Tian, Xiaozhe Shen, Qingyang Gao +12
Boson peak, the excess low energy excitations in the terahertz regime, is one of the most unique features of disordered systems and has been linked to many anomalous properties of…
Role of equilibrium fluctuations in light-induced order
Alfred Zong, Pavel E. Dolgirev, Anshul Kogar +17
Engineering novel states of matter with light is at the forefront of materials research. An intensely studied direction is to realize broken-symmetry phases that are "hidden" under…
Unconventional hysteretic transition in a charge density wave
B. Q. Lv, Alfred Zong, D. Wu +25
Hysteresis underlies a large number of phase transitions in solids, giving rise to exotic metastable states that are otherwise inaccessible. Here, we report an unconventional hyste…
Visualizing femtosecond dynamics with ultrafast electron probes through terahertz compression and time-stamping
Mohamed A. K. Othman, Emma C. Snively, Annika E. Gabriel +9
Visualizing ultrafast dynamics at the atomic scale requires time-resolved pump-probe characterization with femtosecond temporal resolution. For single-shot ultrafast electron diffr…
Interlayer magnetophononic coupling in MnBi2Te4
Hari Padmanabhan, Maxwell Poore, Peter Kim +16
The emergence of magnetism in quantum materials creates a platform to realize spin-based applications in spintronics, magnetic memory, and quantum information science. A key to unl…
Universal phase dynamics in VO2 switches revealed by ultrafast operando diffraction
Aditya Sood, Xiaozhe Shen, Yin Shi +9
Strongly correlated materials that exhibit an insulator-metal transition are key candidates in the search for new computing platforms. Understanding the pathways and timescales und…
Dynamic lattice distortions driven by surface trapping in semiconductor nanocrystals
Burak Guzelturk, Benjamin L. Cotts, Dipti Jasrasaria +26
Nonradiative processes limit optoelectronic functionality of nanocrystals and curb their device performance. Nevertheless, the dynamic structural origins of nonradiative relaxation…
