• Abstract: A comprehensive theoretical approach to describe the electron-ion radiative recombination in the presence of intense, short laser pulses, which accounts for nondipole corrections is presented. It is based on the relativistic Coulomb-Volkov solution describing an electron in a combined Coulomb potential and a laser field, which is systematically expanded in powers of $1/c$. Thus, it allows us to trace the origin of nondipole effects observed in the spectrum of emitted radiation. Hence, as we demonstrate for high-frequency pulses assisting the process, a significant extension of the cutoff and asymmetry in angular distributions of the emitted radiation can be attributed to the electron recoil off the laser pulse. In addition, we investigate a possibility of enhancing the efficiency of the generated high-energy radiation by chirping the pulse.

  vortex electron interactions with electromagnetic fields are essential for advancing particle acceleration techniques, scattering theory in background fields, and obtaining novel electron beams for material diagnostics. We study the propagation of vortex electrons in linearly polarized (LP) and circularly polarized (CP) laser pulses, both separately and in their combined form in two-mode laser pulses. Our findings demonstrate the versatile control over vortex electrons via laser pulses, with our formalism providing a reference for vortex scattering in laser backgrounds and inspiring the laser-controlled achievement of novel vortex modes as targeted diagnostic probes for specialized materials.

• Directional spontaneous emission in photonic crystal slabs [49.1574468325115]
  Spontaneous emission is a fundamental out-of-equilibrium process in which an excited quantum emitter relaxes to the ground state due to quantum fluctuations. One way to modify these photon-mediated interactions is to alter the dipole radiation patterns of the emitter, e.g., by placing photonic crystals near them. Our study delves into the interaction between these directional emission patterns and the aforementioned variables, revealing the untapped potential to fine-tune collective quantum optical phenomena.
