Reversible Superdense Ordering of Tetragonal Lithium in a Layered Material
Natalie L. Williams, Stephen D. Funni, Sihun Lee +14
Understanding lithium (Li) ordering and dynamics is foundational in energy storage. X-ray based experimental methods do not simultaneously provide atomic structure information toge…
Synthesis of epitaxial TaO thin films on AlO by suboxide molecular-beam epitaxy and thermal laser epitaxy
Yorick A. Birkhölzer, Anna S. Park, Noah Schnitzer +28
Tantalum dioxide (TaO2) is a metastable tantalum compound. Here, we report the epitaxial stabilization of TaO2 on Al2O3 (1-102) (r-plane sapphire) substrates using suboxide molecul…
Picosecond expansion in LaAlO3 resonantly driven by infrared-active phonons
Jakob Gollwitzer, Jeffrey Z. Kaaret, Y. Eren Suyolcu +19
We investigate the ultrafast structural dynamics of LaAlO3 thin films driven by short mid-infrared laser pulses at 20 THz. Time-resolved X-ray diffraction reveals an immediate latt…
Coherent control of the translational and point group symmetries of crystals with light
Guru Khalsa, Jeffrey Z. Kaaret, Nicole A. Benedek
We use theory and first-principles calculations to explore mechanisms for control of the translational and point group symmetries of crystals in ultrafast optical experiments. We f…
Picosecond volume expansion drives a later-time insulator-metal transition in a nano-textured Mott Insulator
Anita Verma, Denis Golež, Oleg Yu. Gorobtsov +24
Technology moves towards ever faster switching between different electronic and magnetic states of matter. Manipulating properties at terahertz rates requires accessing the intrins…
A Strategy to Identify Materials Exhibiting a Large Nonlinear Phononics Response: Tuning the Ultrafast Structural Response of LaAlO with Pressure
Jeffrey Z. Kaaret, Guru Khalsa, Nicole A. Benedek
We use theory and first-principles calculations to investigate how structural changes induced by ultrafast optical excitation of infrared-active phonons change with hydrostatic pre…
