Electron modulation and ultrafast near-field imaging with vectorial laser fields
J. Kuttruff, L. Möhrle, L. Ciorciaro +2
Controlled interaction of laser light with electron beams is fundamental for ultrafast electron microscopy and electron-based quantum optics, yet their direct coupling is forbidden…
Localized Photon Absorption in a Single-Crystalline Material
Daniel Kazenwadel, Jacob Holder, Livio Ciorciaro +6
The absorption of light is one of the most fundamental processes in condensed-matter physics and optics. Here we investigate under which conditions laser light is absorbed by a cry…
AC-Stark Spectroscopy of Interactions between Moiré Excitons and Polarons
B. Evrard, H. S. Adlong, A. A. Ghita +6
We use nonlinear pump-probe spectroscopy to study optical excitations in a charge-tunable MoSe\WS moiré heterostructure. An intense red-detuned laser pulse creates a photon…
Kinetic Magnetism in Triangular Moiré Materials
Livio Ciorciaro, Tomasz Smolenski, Ivan Morera +8
Magnetic properties of materials ranging from conventional ferromagnetic metals to strongly correlated materials such as cuprates originate from Coulomb exchange interactions. The…
High-temperature kinetic magnetism in triangular lattices
Ivan Morera, Márton Kanász-Nagy, Tomasz Smolenski +3
We study kinetic magnetism for the Fermi-Hubbard models in triangular type lattices, including a zigzag ladder, four- and six-legged triangular cylinders and a full two-dimensional…
Optical signatures of periodic magnetization: the moiré Zeeman effect
Alex Gómez Salvador, Clemens Kuhlenkamp, Livio Ciorciaro +2
Detecting magnetic order at the nanoscale is of central interest for the study of quantum magnetism in general, and the emerging field of moiré magnets in particular. Here, we anal…
Observation of Magnetic Proximity Effect Using Resonant Optical Spectroscopy of an Electrically Tunable MoSe/CrBr Heterostructure
Livio Ciorciaro, Martin Kroner, Kenji Watanabe +2
Van der Waals heterostructures combining two-dimensional magnetic and semiconducting layers constitute a promising platform for interfacing magnetism, electronics, and optics. Here…
Fermi edge singularities in transport through lateral GaAs quantum dots
Tobias Krähenmann, Livio Ciorciaro, Christian Reichl +4
We measure tunnelling currents through electrostatically defined quantum dots in a GaAs/AlGaAs heterostructure connected to two leads. For certain tunnelling barrier configurations…
