Stimulated Parametric Down-Conversion: From Foundational Coherence to Structured Light Applications
M. F. Z. Arruda, M. G. Damaceno, G. H. dos Santos +4
Stimulated parametric down-conversion (StimPDC) is the seeded version of the process that underlies much of photonic quantum information. Replacing the vacuum at one input port wit…
Brazilian Twin Photons 32nd anniversary
Renné Medeiros de Araújo, Raphael César Souza Pimenta, Lucas Marques Fagundes +4
We present a historical review of the development and impact of spontaneous parametric down-conversion (SPDC) in Brazil, marking over three decades since the first twin-photon expe…
Evaluation of Twisted Gaussian Schell Model beams produced with phase randomized coherent fields
Gustavo Cañas, Esteban Sepúlveda Gómes, Gustavo Henrique dos Santos +6
The twisted Gaussian Schell Model describes a family of partially coherent beams that present several interesting characteristics, and as such have attracted attention in classical…
Full Thermalization of a Photonic Qubit
A. G. de Oliveira, R. M. Gomes, V. C. C. Brasil +3
The generalized amplitude damping (GAD) quantum channel implements the interaction between a qubit and an environment with arbitrary temperature and arbitrary interaction time. Her…
Quantum-optical Description of Phase Conjugation of Vector Vortex Beams in Stimulated Parametric Down Conversion
A. G. de Oliveira, N. Rubiano da Silva, R. Medeiros de Araújo +2
We present a quantum optics approach for describing stimulated parametric down conversion in the two type-I crystal "sandwich" configuration, which allows for parametric interactio…
Nanoscale diffractive probing of strain dynamics in ultrafast transmission electron microscopy
Armin Feist, Nara Rubiano da Silva, Wenxi Liang +2
The control of optically driven high-frequency strain waves in nanostructured systems is an essential ingredient for the further development of nanophononics. However, broadly appl…
Ultrafast transmission electron microscopy using a laser-driven field emitter: femtosecond resolution with a high coherence electron beam
Armin Feist, Nora Bach, Nara Rubiano da Silva +12
We present the development of the first ultrafast transmission electron microscope (UTEM) driven by localized photoemission from a field emitter cathode. We describe the implementa…
A light induced metastable magnetic texture uncovered by in-situ Lorentz microscopy
Tim Eggebrecht, Marcel Möller, J. Gregor Gatzmann +7
Magnetic topological defects, including vortices and Skyrmions, can be stabilized as equilibrium structures by tuning intrinsic magnetic interactions and stray field geometries. He…
