The momentum and photon energy dependence of the circular dichroic photoemission in the bulk Rashba semiconductors BiTeX (X = I, Br, Cl)
A. Crepaldi, F. Cilento, M. Zacchigna +14
Bulk Rashba systems BiTeX (X = I, Br, Cl) are emerging as important candidates for developing spintronics devices, because of the coexistence of spin-split bulk and surface states,…
Momentum resolved spin dynamics of bulk and surface excited states in the topological insulator
C. Cacho, A. Crepaldi, M. Battiato +16
The prospective of optically inducing a spin polarized current for spintronic devices has generated a vast interest in the out-of-equilibrium electronic and spin structure of topol…
Localised vibrations in superconducting YBCO revealed by ultra-fast optical coherent spectroscopy
Fabio Novelli, Gianluca Giovannetti, Adolfo Avella +6
The interaction between phonons and high-energy excitations of electronic origin in cuprates and their role in the superconducting mechanisms is still controversial. Here we use co…
Photo-enhanced antinodal conductivity in the pseudogap state of high Tc cuprates
Federico Cilento, Stefano Dal Conte, Giacomo Coslovich +18
A major challenge in understanding the cuprate superconductors is to clarify the nature of the fundamental electronic correlations that lead to the pseudogap phenomenon. Here we us…
Witnessing the formation and relaxation of massive quasi-particles in a strongly correlated electron system
Fabio Novelli, Giulio De Filippis, Vittorio Cataudella +17
The non-equilibrium semiconductors physics is based on the paradigm that different degrees of freedom interact on different timescales. In this context the photo-excitation is ofte…
Ultrafast Dynamics of Massive Dirac Fermions in Bilayer Graphene
Søren Ulstrup, Jens Christian Johannsen, Federico Cilento +14
Bilayer graphene is a highly promising material for electronic and optoelectronic applications since it is supporting massive Dirac fermions with a tuneable band gap. However, no c…
