Nature Physics (2021)

We combine different imaging techniques and angle-resolved photoemission with simultaneous real- and momentum-space resolution (nano-ARPES) to directly map the band dispersion in twisted bilayer graphene...

Phys. Rev. Lett. 124, 106402 (2020)

We report high-resolution angle-resolved photoemission measurements on single crystals of Pt2HgSe3 grown by high-pressure synthesis. Our data reveal a gapped Dirac nodal line whose (001) projection separates...

Phys. Rev. X 6, 031021 (2016)

We report a combined experimental and theoretical study of the candidate type-II Weylsemimetal MoTe2. Using laser-based angle-resolved photoemission, we resolve multiple distinct Fermi arcs. All surface...

Nature Mater 15, 835–839 (2016)

We use the prototypical two-dimensional electron liquid (2DEL) at the SrTiO3(001) surface to reveal a remarkably complex evolution of electron–phonon coupling with the tunable carrier density of this...

Phys. Rev. Lett. 115, 176402 (2015)

We report ARPES experiments on the electron doped Heisenberg antiferromagnet (Sr1−xLax)2IrO4. For a doping level of x=0.05, we find an unusual metallic state with coherent nodal excitations and an antipodal ...

Advances Materials, 27 (26), 3894-3899 (2015)

The origin of the two-dimensional electron gas (2DEG) stabilized at the bare surface of SrTiO3 (001) is investigated. Using high-resolution angle resolved photoemission and core level spectroscopy we show...

Phys. Rev. Lett. 113, 256402 (2014)

We characterize the electron doping evolution of (Sr1−xLax)3Ir2O7. Concomitant with the metal insulator transition around x≈0.05 we find the emergence of coherent quasiparticle states forming a closed...

Phys. Rev. Lett. 113, 177601 (2014)

We report on the formation of a two-dimensional electron gas (2DEG) at the bare surface of (111) oriented SrTiO3. Angle resolved photoemission experiments reveal highly itinerant carriers with a sixfold...
