Time-and-angle-resolved photoemission spectroscopy with mid-IR pump and 30 fs EUV probe

Optics Infobase Conference Papers (2014)

Authors:

CM Cacho, JC Petersen, I Gierz, H Liu, S Kaiser, R Chapman, ICE Turcu, A Cavalleri, E Springate

Abstract:

Time- and angle-resolved photoemission spectroscopy directly enables observation of electron dynamics in condensed matter. Using EUV high harmonic probe extends the observation window in energy and momentum. Tuneable mid-infrared pumping allows control of excitation mechanisms.Research in Optical Sciences © OSA 2014.

Transient atomic structure of vibrationally excited YBCO with enhanced superconducting coherence above Tc

Optics InfoBase Conference Papers (2014)

Authors:

R Mankowsky, A Subedi, M Först, SO Mariager, M Chollet, H Lemke, J Robinson, J Glownia, M Minitti, A Frano, M Fechner, N Spaldin, T Loew, M Le Tacon, B Keimer, A Georges, A Cavalleri

Abstract:

Nonlinear lattice excitation in YBa2Cu3O6.5 has been shown recently to transiently induce signatures of superconducting coherence up to room temperature. Here, we present ultrafast x-ray diffraction measurements used to determine the corresponding atomic structure. © 2014 OSA.
