Universidade Estadual de Campinas (UNICAMP). Instituto de Física Gleb Wataghin (IFGW) (Institutional affiliation from the last research proposal) Birthplace: Brazil
Professor at the Gleb Wataghin Institute of Physics at the University of Campinas (Unicamp) since 2019 (MS 3.2). He received his Ph.D. in Physics in 2012 from the University of São Paulo (USP) and completed a postdoctoral fellowship at the Massachusetts Institute of Technology (MIT) between 2013 and 2014. His main research topics include ultrashort laser pulses, nonlinear optics, ultrafast terahertz spectroscopy of advanced bulk materials and low-dimensional materials (quantum dots and 2D), generation of ultrashort X-ray pulses, and dual-comb spectroscopy.

This proposal aims to develop laboratory-scale high photon flux sources of coherent radiation in vacuum ultraviolet (6 to 20 eV) and ultrabroadband terahertz (0.1 to 25 THz / 0.4 to 100 meV) using femtosecond lasers. The development of this coherent vacuum ultraviolet source constitutes the first step towards the construction of a laboratory scale beamline with parameters optimized for th…
Terahertz (THz) spectroscopy is an innovative technique with growing applications in science and technology, encompassing the characterization of semiconductor materials, quantum materials, and pharmaceutical compounds. However, the absorption of THz radiation by atmospheric water vapor poses a significant obstacle, particularly at frequencies above 1 THz, compromising the quality and acc…
In this master's project, the student will employ the spectroscopic techniques THz-TDS (terahertz time domain spectroscopy) and OPTP (optical pump terahertz probe) to investigate the spectral dependence of the complex optical conductivity (real and imaginary parts) in semiconductor systems (bulk, quantum dots, nanowires and two dimensional). Additionally, studies will be conducted to dete…
In this PhD project, the terahertz time-domain spectroscopy (THz-TDS) technique with ultra-wide bandwidth (1 to 40 meV) will be employed to obtain the spectral dependence of the complex optical conductivity (real and imaginary parts) of advanced materials in both steady-state and transient regimes (pump-probe). Strongly correlated materials (superconductors, heavy-fermions, topological in…

This undergraduate research project aims to first familiarize the student with concepts related to ultrashort pulses and characterizationmethods based on optical autocorrelation measurements. Then, the student will implement a ultrashort pulsecharacterization technique known as FROG (Frequency resolved optical gating). This technique is based on the spectral analysis of an temporal autoco…
Because of the strong interaction of terahertz radiation with free charges, the terahertz spectral region, located between 0.1 and 10 THz (0.41 to 41 meV), is extremely suitable for characterizing transport properties in bulk or nanoscale semiconductors. Because of its low energy per photon (0.41 to 41 meV) has also been widely used to characterize low energy excitations in complex materi…
The main goal of the proposed work for the postdoctoral position consists on the implementation of optical spectroscopic techniques with ultrafast temporal resolution of the order of tens of femtoseconds, to investigate the dynamics of photophysical and photochemical processes. The main processes to be investigated consist of the photoisomerization reactions of azocompounds and intramolec…
The main objective of the proposed project for the research internship abroad, is the implementation of the phase matched high order harmonic generation by the guided wave technique using ultrashort laser pulses in the mid infrared with extreme peak intensities for obtaining high-flux coherent radiation covering the soft X-ray spectral region called "water window" (280-530 eV). This impl…
