Attosecond sublevel beating and nonlinear dressing on the 3d-to-5p and 3p-to-5s core-transitions at 91.3 eV and 210.4 eV in krypton
Seres, Enikoe; Seres, Jozsef; Namba, Shinichi; Afa, Iduabo John; Serrat Jurado, Carles (2017-12-11)
Article
Accés obertApplying extreme ultraviolet (XUV) transient absorption spectroscopy, the dynamics of the two laser dressed transitions 3d5/2-to-5p3/2 and 3p3/2-to-5s1/2 at photon energies of 91.3 eV and 210.4 eV were examined with ... -
Control of rubidium low-lying Rydberg states with trichromatic femtosecond p pulses for ultrafast quantum information processing
Afa, Iduabo John; Font García, Josep Lluís; Serrat Jurado, Carles (2017-11-20)
Article
Accés obertWe propose an ultrafast femtosecond time scale trichromatic π-pulse illumination scheme for coherent excitation and manipulation of low-lying Rydberg states in rubidium. Selective population of nP3/2 levels with principal ... -
Etching techniques for thinning silicon wafers for ultra thin high efficiency IBC solar cells
Afa, Iduabo John (Universitat Politècnica de Catalunya, 2014-09-08)
Projecte Final de Màster Oficial
Accés obert[ANGLÈS] High efficiency Interdigitated back contact (IBC) solar cells help reduce the area of solar panels needed to supply sufficient amount of energy for household consumption. We believe that a properly passivated IBC ... -
Quantum control of population transfer and vibrational states via chirped pulses in four level density matrix equations
Afa, Iduabo John; Serrat Jurado, Carles (2016-11-15)
Article
Accés obertWe investigate the effect of chirped excitation and the excitation detuning on the coherent control of population transfer and vibrational states in a four---level system. Density matrix equations are studied for optimally ... -

Seres, Enikoe; Seres, Jozsef; Afa, Iduabo John; Serrat Jurado, Carles; Namba, Shinichi (Optica Publishing Group, 2019)
Text en actes de congrés
Accés restringit per política de l'editorialA soft-X-ray high harmonic source has been developed and applied for time-resolved Xray absorption spectroscopy of Krypton gas, Silicon and Zirconium solids at laser dressed transitions up to 220 eV with attosecond resolution. -
Trichromatic pi-pulse for ultrafast total inversion of a four-level ladder system
Serrat Jurado, Carles; Corbera Subirana, Montserrat; Afa, Iduabo John (2015-11-30)
Article
Accés obertWe present a numerical solution for complete population inversion in a four-level ladder system obtained by using a full p-pulse illumination scheme with resonant ultrashort phase-locked Gaussian laser pulses. We find that ... -
Ultrafast quantum control of atoms and molecules : a density matrix approach
Afa, Iduabo John (Universitat Politècnica de Catalunya, 2018-01-24)
Tesi
Accés obertControl is important for transferring theoretical scientific knowledge into practical technology for applications in numerous fields. This is why coherent control study is significant on every timescale to have a complete ...
