In the field of Nuclear Physics, we focus on the description of nuclear decay processes in the presence of low energy and extreme high intensity (with peak intensity I > 10 20W/cm 2) monochromatic electromagnetic fields (lasers), mainly within the framework of non-Hermitian quantum mechanics with different kinds of nuclear models. The recent development of extreme high intensity lasers within the Extreme Light Infrastructure (ELI) programinitiated by the EU (and of which Hungary is one of the main participants) provides actuality for the theoretical study of nuclear processes interacting with such high intensity lasers.
Our major research fields:
  • The study of nuclear decay processes (alpha, beta and gamma decays) in intense electromagnetic fields.
    The description of low energy nuclear reactions in intense electromagnetic fields.

Active research:

  • The description of alpha-tunneling in extreme high intensity laser fields within the framework of non-Hermitian quantum mechanicsand the (t,t')-formalismwith three dimensional models.

Planned research in the near future:

  • Formulating a feasible model to describe the process of beta-decay with special regards to the Electron Capture-process in the presence of an extreme high intensity coherent electromagnetic field using quantum field theoretical approaches.
