In the last two decades non-equilibrium spectroscopies have evolved from avant-garde
studies to crucial tools for expanding our understanding of the physics of strongly correlated …

The effect of electron–phonon coupling in materials can be interpreted as a dressing of the
electronic structure by the lattice vibration, leading to vibrational replicas and hybridization of …

We briefly review a few recent progresses of the ultrafast generation and detection of
coherent phonons in various types of quantum materials. Both the shared properties and …

The combined effects of electron–A1g phonon and Rashba spin–orbit couplings on the
electronic spectrum of graphene in the presence of Haldane interaction induced by photo …

We used 4D ultrafast electron microscopy (UEM) to directly image femtosecond
photoinduced structural dynamics in single-crystal LaFeAsO at initial temperatures of 300 …

We present the effects of spin-orbit coupling on the low-energy bands and Fermi surface of
the recently discovered pressure-induced superconductor CrAs. We apply the Löwdin down …

We formulate the problem of unconventional d− wave superconductivity, with phase
fluctuations, pseudogap phenomenon, and local Cooper pairs, in terms of a synchronization …

While the mid-infrared spectral region spans more than 3000 cm− 1, ultrafast mid-IR
spectroscopies are normally limited to the spectral bandwidth that can be generated in …

A femtosecond pump-probe setup is described that is optimised for broadband transient
reflectivity experiments on solid samples over a wide temperature range. By combining high …

We study the tight-binding dispersion of the recently discovered superconductor K 2 Cr 3 As
3, obtained from Wannier projection of Density Functional Theory (DFT) results. In order to …
