Anomalous anisotropic exciton temperature dependence in rutile TiO2

Majed Chergui, Edoardo Baldini

Elucidating the details of electron-phonon coupling in semiconductors and insulators is a topic of pivotal interest, as it governs the transport mechanisms and is responsible for various phenomena such as spectral-weight transfers to phonon sidebands and s ...

Clocking the onset of bilayer coherence in a high-Tc cuprate

Fabrizio Carbone, Frank van Mourik, Christopher Alexander Arrell, Edoardo Baldini, Andreas Helmut Christian Mann, Dragan Mihailovic

In cuprates, a precursor state of superconductivity is speculated to exist above the critical temperature T-c. Here we show via a combination of far-infrared ellipsometry and ultrafast broadband optical spectroscopy that signatures of such a state can be o ...

Nonequilibrium Dynamics of Collective Excitations in Strongly Interacting and Correlated Quantum Systems

Edoardo Baldini

Revealing the emergence and the dynamics of collective excitations in complex matter is a subject of pivotal importance, as it provides insight into the strength and spatial distribution of interactions and correlations. At the same time, collectivity lies ...

Real-Time Observation of Phonon-Mediated σ−π Interband Scattering in MgB2

Fabrizio Carbone, Edoardo Baldini, Andreas Helmut Christian Mann, Simone Borroni, Ting Tan

In systems having an anisotropic electronic structure, such as the layered materials graphite, graphene, and cuprates, impulsive light excitation can coherently stimulate specific bosonic modes, with exotic consequences for the emergent electronic properti ...

The LOUVRE Laboratory: State-of-the-Art Ultrafast Ultraviolet Spectroscopies for Molecular and Materials Science

Majed Chergui, Natalia Nagornova, Frank van Mourik, Edoardo Baldini, Thomas Charles Henry Rossi, Malte Oppermann, Tania Palmieri, Lars-Hendrik Mewes, Benjamin Bauer, Aurelio Oriana

We describe the facilities for ultraviolet studies in the femtosecond to nanosecond time domain. These facilities consist of: i) a set-up for deep-ultraviolet spectroscopy in the 260–380 nm range in both pump and probe pulses for transient absorption/refle ...

Strongly bound excitons in anatase TiO2 single crystals and nanoparticles

Majed Chergui, Marco Grioni, Edoardo Baldini, Arnaud Magrez, Gerald Auböck, Helmuth Berger, Simon Karl Moser

Anatase TiO2 is among the most studied materials for light-energy conversion applications, but the nature of its fundamental charge excitations is still unknown. Yet it is crucial to establish whether light absorption creates uncorrelated electron-hole pai ...

Interfacial Electron Injection Probed by a Substrate-Specific Excitonic Signature

Majed Chergui, Edoardo Baldini, Enrico Pomarico, Thomas Charles Henry Rossi, Malte Oppermann, Tania Palmieri, Gerald Auböck

Ultrafast interfacial electron transfer in sensitized solar cells has mostly been probed by visible-to-terahertz radiation, which is sensitive to the free carriers in the conduction band of the semiconductor substrate. Here, we demonstrate the use of deep- ...

A versatile setup for ultrafast broadband optical spectroscopy of coherent collective modes in strongly correlated quantum systems

Fabrizio Carbone, Edoardo Baldini, Frank van Mourik, Christopher Alexander Arrell, Andreas Helmut Christian Mann, Simone Borroni

A femtosecond pump-probe setup is described that is optimised for broadband tran- sient reflectivity experiments on solid samples over a wide temperature range. By combining high temporal resolution and a broad detection window, this apparatus can investig ...

Probing the coupling between a doublon excitation and the charge-density wave in TaS2 by ultrafast optical spectroscopy

Arnaud Magrez, Fabrizio Carbone, Edoardo Baldini, Helmuth Berger, Andreas Helmut Christian Mann, Ahmad Odeh

Recently, the switching between the different charge-ordered phases of 1T-TaS2 has been probed by ultrafast techniques, revealing unexpected phenomena such as "hidden" metastable states and peculiar photoexcited charge patterns. Here, we apply broadband pu ...

Probing the electron-phonon interaction in correlated systems with coherent lattice fluctuation spectroscopy

Fabrizio Carbone, Frank van Mourik, Edoardo Baldini, Christopher Alexander Arrell, Andreas Helmut Christian Mann, Kazimierz Conder

Tailoring the properties of correlated oxides is accomplished by chemical doping, pressure, temperature, or magnetic field. Photoexcitation is a valid alternative to reach out-of-equilibrium states otherwise inaccessible. Here, we quantitatively estimate t ...
