What do the two times in two-time correlation functions mean for interpreting tr-ARPES?

J. K. Freericks, Alexander F. Kemper

Time-resolved angle-resolved photoemission spectroscopy is one of the most powerful pump-probe measurements of materials driven far from equilibrium. Unlike the linear-response reg…

Probing the interplay between lattice dynamics and short-range magnetic correlations in CuGeO3 with femtosecond RIXS

E. Paris, C. W. Nicholson, S. Johnston +13

Investigations of magnetically ordered phases on the femtosecond timescale have provided significant insights into the influence of charge and lattice degrees of freedom on the mag…

Detailed band structure of twinned and detwinned BaFeAs studied with angle-resolved photoemission spectroscopy

H. Pfau, C. R. Rotundu, J. C. Palmstrom +6

We study the band structure of twinned and detwinned BaFeAs using angle-resolved photoemission spectroscopy (ARPES). The combination of measurements in the ordered and norm…

All-optical nonequilibrium pathway to stabilizing magnetic Weyl semimetals in pyrochlore iridates

Gabriel E. Topp, Nicolas Tancogne-Dejean, Alexander F. Kemper +2

Nonequilibrium many-body dynamics is becoming one of the central topics of modern condensed matter physics. Floquet topological states were suggested to emerge in photodressed band…

Dynamics of correlation-frozen antinodal quasiparticles in superconducting cuprates

Federico Cilento, Giulia Manzoni, Andrea Sterzi +15

Many puzzling properties of high- superconducting (HTSC) copper oxides have deep roots in the nature of the antinodal quasiparticles, the elementary excitations with wavevecto…

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…
