Direct characterization of photo-induced lattice dynamics in BaFe2As2

S. Gerber, K. W. Kim, Y. Zhang +21

Ultrafast light pulses can modify the electronic properties of quantum materials by perturbing the underlying, intertwined degrees of freedom. In particular, iron-based superconduc…

Distinguishing bulk and surface electron-phonon coupling in the topological insulator Bi2Se3 using time-resolved photoemission spectroscopy

Jonathan A. Sobota, Shuolong Yang, Dominik Leuenberger +6

We report time- and angle-resolved photoemission spectroscopy measurements on the topological insulator Bi2Se3. We observe oscillatory modulations of the electronic structure of bo…

A balancing act: Evidence for a strong subdominant d-wave pairing channel in

T. Böhm, A. F. Kemper, B. Moritz +7

We present an analysis of the Raman spectra of optimally doped based on LDA band structure calculations and the subsequent estimation of effective R…

Transient Exchange Interaction in a Helical Antiferromagnet

M. C. Langner, S. Roy, A. F. Kemper +8

We have performed time-resolved resonant x-ray scattering studies in the Lanthanide metal Dy to reveal the dynamic response of the helical order exchange coupling to injection of u…

Direct Optical Coupling to an Unoccupied Dirac Surface State in the Topological Insulator BiSe

Jonathan A. Sobota, Shuolong Yang, Alexander F. Kemper +9

We characterize the occupied and unoccupied electronic structure of the topological insulator BiSe by one-photon and two-photon angle-resolved photoemission spectroscopy an…

Phase Fluctuations and the Absence of Topological Defects in Photo-excited Charge Ordered Nickelate

W. S. Lee, Y. D. Chuang, R. G. Moore +32

The dynamics of an order parameter's amplitude and phase determines the collective behaviour of novel states emerged in complex materials. Time- and momentum-resolved pump-probe sp…
