Scattering and transmission techniques for time-resolved studies using coherent light sources
Arun Ravindran, Giovanni De Ninno
Doktorska disertacija
Oznake: ultrafast optics;FELs;HHG;femtomagnetism;pump-probe;ultrafast studies;dissertations;
The ability to probe and manipulate matter on femtosecond timescales has transformed our understanding of ultrafast phenomena in magnetic, molecular, and condensed matter systems. These rapid processes governed by interactions between charge, spin, and lattice degrees of freedom hold the key to the ...

Uncovering the nature of transient and metastable nonequilibrium phases in 1T − TaS[sub]2
Tanusree Saha, Arindam Pramanik, Barbara Ressel, A. Ciavardini, F. Frassetto, Federico Galdenzi, L. Poletto, Arun Ravindran, Primož Rebernik Ribič, Giovanni De Ninno
Izvirni znanstveni članek
Oznake: angle resolved photoemission;time resolved photoemission;2D materials;charge density wave;Mott insulator;
Complex systems are characterized by strong coupling between different microscopic degrees of freedom. Photoexcitation of such materials can drive them into new transient and metastable hidden phases that may not have any counterparts in equilibrium. By exploiting femtosecond time- and angle-resolve ...

Optical control of a metastable phase in the charge-density-wave Mott insulator 1T-TaS[sub]2 investigated using time-resolved ARPES
Tanusree Saha, Arindam Pramanik, Rokaya Osama, F. Frassetto, Damjan Križmančič, L. Poletto, Arun Ravindran, Barbara Ressel, Primož Rebernik Ribič, Giovanni De Ninno
Izvirni znanstveni članek
Oznake: time resolved photoemission;charge density waves;metastable phases;dichalcogenides;
Light-induced metastable phases are exotic, long-lived out-of-equilibrium states of matter. Optical control offers a powerful approach to engineering these phases, enabling dynamic tuning of their electronic and structural properties. Using time- and angle-resolved photoemission spectroscopy, we inv ...

ǂA ǂmultipurpose setup for ultrafast XUV spectroscopies
Arun Ravindran, Filippo Bencivenga, Emanuele Coccia, Giovanni De Ninno, Laura Foglia, Riccardo Mincigrucci, Eleonora Luppi, Barbara Ressel, Maurizio Sacchi, Jurij Urbančič, C. Spezzani
Izvirni znanstveni članek
Oznake: ultrafast optics;high harmonic generation;XUV scattering;pump-probe;
A tabletop setup for ultrafast x-ray ultraviolet (XUV) magnetic scattering and molecular spectroscopy has been developed at the Laboratory of Quantum Optics at the University of Nova Gorica. This system provides XUV light in a spectral range allowing the study of M-absorption edges in pure transitio ...
