Flat-band optical phonons in twisted bilayer graphene
Emmanuele Cappelluti, Jose Angel Silva-Guillén, Habib Rostami +1
Twisting bilayer sheets of graphene have been proven to be an efficient way to manipulate the electronic Dirac-like properties, resulting in flat bands at magic angles. Inspired by…
Properties and challenges of hot-phonon physics in metals: MgB and other compounds
Emmanuele Cappelluti, Fabio Caruso, Dino Novko
The ultrafast dynamics of electrons and collective modes in systems out of equilibrium is crucially governed by the energy transfer from electronic degrees of freedom, where the en…
Strain-driven chiral phonons in two-dimensional hexagonal materials
Habib Rostami, Francisco Guinea, Emmanuele Cappelluti
Hexagonal two-dimensional materials with broken inversion symmetry (as BN or transition metal dichalcodenides) are known to sustain chiral phonons with finite angular momentum, add…
Many-Body Effects in Third Harmonic Generation of Graphene
Habib Rostami, Emmanuele Cappelluti
The low-energy (intraband) range of the third harmonic generation of graphene in the terahertz regime is governed by the damping terms induced by the interactions. A controlled man…
Dominant Role of Two-Photon Vertex in Nonlinear Response of Dirac Materials
Habib Rostami, Emmanuele Cappelluti
Using a conserving Baym-Kadanoff approach, we present a fully compelling theory of nonlinear dc response of a Dirac system to electric fields in the presence of disorder scattering…
Ultrafast Hot Phonon Dynamics in MgB Driven by Anisotropic Electron-Phonon Coupling
D. Novko, F. Caruso, C. Draxl +1
The zone-center modes play a crucial role in MgB, controlling the scattering mechanisms in the normal state as well the superconducting pairing. Here, we demonstrate v…
