Hydrogen-Bond Donor-Acceptor Imbalance in Low-Frequency Terahertz Water Spectra
Lilian Najm Alsayed, Florian Pabst, Giuseppe Cassone +2
The low-frequency dielectric response of liquid water is commonly described by a dominant Debye relaxation together with additional faster contributions whose microscopic origin re…
Cavity-enhanced superconducting response in an underdoped cuprate
Angela Montanaro, Vadim Plastovets, Nitesh Khatiwada +15
Superconductors carry electrical current without resistance when paired electrons condense into a coherent macroscopic quantum state. In underdoped cuprates, evidence suggests that…
Temperature-independent non-linear terahertz transmission by liquid water
Célia Millon, Johannes Schmidt, Sashary Ramos +4
Liquid water is one of the most studied substances, yet many of its properties are difficult to rationalize. The uniqueness of water is rooted in the dynamic network of hydrogen-bo…
Water Solvation of Charged and Neutral Gold Nanoparticles
Fabio Novelli, Miguel Bernal Lopez, Gerhard Schwaab +2
Gold nanoparticles are unique electrocatalysts for oxygen reduction, carbon dioxide reduction, and alcohol oxidation. Electrocatalytic processes are influenced by the interaction w…
Strong Anisotropy in Liquid Water upon Librational Excitation using Terahertz Laser Fields
Fabio Novelli, Luis Ruiz Pestana, Kochise C. Bennett +9
Tracking the excitation of water molecules in the homogeneous liquid is challenging due to the ultrafast dissipation of rotational excitation energy through the hydrogen-bonded net…
Persistent coherence of quantum superpositions in an optimally doped cuprate revealed by 2D spectroscopy
Fabio Novelli, Jonathan O. Tollerud, Dharmalingam Prabhakaran +1
Understanding of the precise mechanisms of high-temperature superconductivity is elusive. In particular, in order to solve the puzzle of the pairing mechanism, it is important to u…
Time-domain THz spectroscopy reveals coupled protein-hydration dielectric response in solutions of native and fibrils of human lyso-zyme
Fabio Novelli, Saeideh Ostovar Pour, Jonathan Tollerud +4
Here we reveal details of the interaction between human lysozyme proteins, both native and fibrils, and their water environment by intense terahertz time domain spectroscopy. With…
Transient THz conductivity of silicon with optical pumping above and below the second indirect transition
Fabio Novelli, Jeffrey A Davis
Here we perform a series of time-resolved experiments where a 100 fs pump pulse is tuned between 528 nm and 555 nm, across the second indirect gap of intrinsic silicon at ~540 nm w…
Phase separation in the non-equilibrium Verwey transition in magnetite
Francesco Randi, Ignacio Vergara, Fabio Novelli +9
We present equilibrium and out-of-equilibrium studies of the Verwey transition in magnetite. In the equilibrium optical conductivity, we find a step-like change at the phase transi…
Vibronic resonances facilitate excited state coherence in light harvesting proteins at room temperature
Fabio Novelli, Ahsan Nazir, Gethin H. Richards +4
Until recently it was believed that photosynthesis, a fundamental process for life on earth, could be fully understood with semi-classical models. However, puzzling quantum phenome…
Localised vibrations in superconducting YBCO revealed by ultra-fast optical coherent spectroscopy
Fabio Novelli, Gianluca Giovannetti, Adolfo Avella +6
The interaction between phonons and high-energy excitations of electronic origin in cuprates and their role in the superconducting mechanisms is still controversial. Here we use co…
Witnessing the formation and relaxation of massive quasi-particles in a strongly correlated electron system
Fabio Novelli, Giulio De Filippis, Vittorio Cataudella +17
The non-equilibrium semiconductors physics is based on the paradigm that different degrees of freedom interact on different timescales. In this context the photo-excitation is ofte…
Mixed regime of light-matter interaction revealed by phase sensitive measurements of the dynamical Franz-Keldysh effect
Fabio Novelli, Daniele Fausti, Francesca Giusti +2
The speed of ultra-fast optical switches is generally limited by the intrinsic electronic response time of the material. Here we show that the phase content of selected electromagn…
Pulsed homodyne Gaussian quantum tomography with low detection efficiency
Martina Esposito, Fabio Benatti, Roberto Floreanini +8
Pulsed homodyne quantum tomography usually requires a high detection efficiency limiting its applicability in quantum optics. Here, it is shown that the presence of low detection e…
Hubbard exciton revealed by time-domain optical spectroscopy
Fabio Novelli, Daniele Fausti, Julia Reul +6
We use broadband ultra-fast pump-probe spectroscopy in the visible range to study the lowest excitations across the Mott-Hubbard gap in the orbitally ordered insulator YVO3. Separa…
