On the survival of Floquet-Bloch states in the presence of scattering
S. Aeschlimann, S. A. Sato, R. Krause +9
Floquet theory has spawned many exciting possibilities for electronic structure control with light with enormous potential for future applications. The experimental realization in…
Microscopic understanding of ultrafast charge transfer in van-der-Waals heterostructures
R. Krause, S. Aeschlimann, M. Chavez-Cervantes +7
Van-der-Waals heterostructures show many intriguing phenomena including ultrafast charge separation following strong excitonic absorption in the visible spectral range. However, de…
Floquet states in dissipative open quantum systems
S. A. Sato, U. De Giovannini, S. Aeschlimann +3
We theoretically investigate basic properties of nonequilibrium steady states of periodically-driven open quantum systems based on the full solution of the Maxwell-Bloch equation.…
Direct evidence for efficient ultrafast charge separation in epitaxial WS/graphene heterostructure
S. Aeschlimann, A. Rossi, M. Chávez-Cervantes +8
We use time- and angle-resolved photoemission spectroscopy (tr-ARPES) to investigate ultrafast charge transfer in an epitaxial heterostructure made of monolayer WS and graphene…
Charge density wave melting in one-dimensional wires with femtosecond sub-gap excitation
M. Chávez-Cervantes, G. E. Topp, S. Aeschlimann +4
Charge density waves (CDWs) are symmetry-broken ground states that commonly occur in low-dimensional metals due to strong electron-electron and/or electron-phonon coupling. The non…
Band Structure Dynamics in Indium Wires
M. Chávez-Cervantes, R. Krause, S. Aeschlimann +1
One-dimensional Indium wires grown on Si(111) substrates, which are metallic at high temperatures, become insulating below K due to the formation of a Charge Density Wave…
Ultrafast Momentum Imaging of Pseudospin-Flip Excitations in Graphene
S. Aeschlimann, R. Krause, M. Chávez-Cervantes +5
The pseudospin of Dirac electrons in graphene manifests itself in a peculiar momentum anisotropy for photo-excited electron-hole pairs. These interband excitations are in fact forb…
Tracking primary thermalization events in graphene with photoemission at extreme timescales
I. Gierz, F. Calegari, S. Aeschlimann +7
Direct and inverse Auger scattering are amongst the primary processes that mediate the thermalization of hot carriers in semiconductors. These two processes involve the annihilatio…
