Orbital-lattice coupling and polaronic dressing of electronic states in PrCaMnO revealed by ultrafast broadband spectroscopy

Emmanuel B. Amuah, Khalid M. Siddiqui, Maurizio Monti +6

The interplay between long-range structural distortions and orbital order, and local short-range phenomena such as polarons, are key for understanding the properties of the mangani…

Determination and correction of spectral phase from principal component analysis of coherent phonons

Emmanuel B. Amuah, Khalid M. Siddiqui, Maurizio Monti +2

Measuring the spectral phase of a pulse is key for performing wavelength resolved ultrafast measurements in the few femtosecond regime. However, accurate measurements in real exper…

Ultrafast loss of lattice coherence in the light-induced structural phase transition of VO

A. S. Johnson, D. Moreno-Mencía, E. B. Amuah +5

In solids, the response of the lattice to photo-excitation is often described by the inertial evolution on an impulsively modified potential energy surface which leads to coherent…

Investigation of spatiotemporal output beam profile instabilities from differentially pumped capillaries

Martin Gebhardt, Emmanuel B. Amuah, Robert Klas +4

Differentially pumped capillaries, i.e., capillaries operated in a pressure gradient environment, are widely used for nonlinear pulse compression. In this work, we show that strong…

Measurement of 10 fs pulses across the entire Visible to Near-Infrared Spectral Range

Allan S. Johnson, Emmanuel B. Amuah, Christian Brahms +1

Tuneable ultrafast laser pulses are a powerful tool for measuring difficult-to-access degrees of freedom in materials science. In general these experiments require the ability to a…
