Revealing the order parameter dynamics of 1T-TiSe following optical excitation
Maximilian Huber, Yi Lin, Nicholas Dale +4
The formation of a charge density wave state is characterized by an order parameter. The way it is established provides unique information on both the role that correlation plays i…
Mapping the dispersion of the occupied and unoccupied band structure in photoexcited 1T-TiSe
Maximilian Huber, Yi Lin, Nicholas Dale +4
Charge density waves (CDW) are states of broken symmetry with a periodic modulation of charge and lattice typically leading to the opening of a gap in the band structure. In the mo…
Ultrafast Angle-Resolved Photoemission Spectroscopy of Quantum Materials
Christopher L. Smallwood, Robert A. Kaindl, Alessandra Lanzara
Techniques in time- and angle-resolved photoemission spectroscopy have facilitated a number of recent advances in the study of quantum materials. We review developments in this fie…
Ultrafast Dynamics of Vibrational Symmetry Breaking in a Charge-ordered Nickelate
Giacomo Coslovich, Alexander F. Kemper, Sascha Behl +6
The ability to probe symmetry breaking transitions on their natural time scales is one of the key challenges in nonequilibrium physics. Stripe ordering represents an intriguing typ…
Influence of Optically Quenched Superconductivity on Quasiparticle Relaxation Rates in Bi2Sr2CaCu2O8+delta
Christopher L. Smallwood, Wentao Zhang, Tristan L. Miller +9
We use time- and angle-resolved photoemission to measure quasiparticle relaxation dynamics across a laser-induced superconducting phase transition in Bi2Sr2CaCu2O8+delta. Whereas l…
Real-time manifestation of strongly coupled spin and charge order parameters in stripe-ordered nickelates via time-resolved resonant x-ray diffraction
Y. D. Chuang, W. S. Lee, Y. F. Kung +27
We investigate the order parameter dynamics of the stripe-ordered nickelate, LaSrNiO, using time-resolved resonant X-ray diffraction. In spite of distinct spi…
