Research interest:

Quantum scattering theory; nonperturbative (expansion, variational) methods; developing computer programs for calculating -decay of light nuclei and -spectroscopic coefficients used in -transfer nuclear reactions; Kohn-, Schwinger-, Newton-, and Ladányi-type calculations of electron-atom collision; developing general multipole-expansion theory; developing localisation procedure for non-local potentials; determining the non-local content of a general heavy-ion optical potential; inverse scattering theory; use of variational methods in three-body scattering; stopping power of an electron gas for ions and anti-particles; detection of unexpected anomalies in the Schwinger and Newton variational methods; developing variational techniques which avoid the anomalies; generalization of algebraic scattering theory to infer internal symmetry of colliding particles; applying inverse quantum scattering to derive complex effective scattering potentials; developing efficient quantum inverse scattering codes at fixed energy; phase shift analysis of nuclear and atomic scattering data. Solitons in Bose-Einstein condensates, stability of two-component Bose-Einstein condensates.
