"Static-field-induced states"
A combination of an atomic or molecular potential and a static electric field creates a "resonator" for an electron. Such a "resonator" can support metastable electronic states. These states do not exists in the absence of the field and hence are called static-field-induced states (SFIS). In my talk, I will present the theory of SFIS and discuss their manifestation in laser-matter interaction observables.

"Molecular Coulomb explosion and dissociative ionization in asymmetric intense laser fields"
"Molecular Coulomb explosion and dissociative ionization in asymmetric intense laser fieldsh
Three-dimensional coincidence ion momentum imaging of simple molecules in phase-controlled two-color intense laser fields is presented. The spatially asymmetric fragmentation is observed both in asymmetric (heteronuclear) and symmetric molecules.  The origins of the phase dependence will be discussed.

"Adiabatic theory of ionization for circularly polarized laser. Application to molecule"
Recently, we have established the adiabatic theory for studying the photomomentum distribution of atom using arbitrarily polarization laser field. In this talk, we present our results for extending this theory to molecular system. We use circular polarization laser field to prevent the electron from recollising with its parent ion. Thus we can eliminate the rescattering part and focus only on the direct ionization part in the photoelectron momentum. The method is illustrated by calculation of photoelectron momentum distribution for 1s\sigma and 2p+ state of H2+.

"Probing two-electron dynamics of helium in time domain via fluorescence channel"
Time-resolved study of electron correlation in many-electron systems remains challenging both experimentally and theoretically. Recently, our Laser Technology Lab has demonstrated a tabletop light source generating pulses with duration of 500 as and energy as high as 1.3 microjoule [E. J. Takahashi et. al., Nat. Commun. 4, 2691 (2013)]. Such high-intensity, short-pulse light source is expected to enhance our ability to probe electron dynamics in time domain. In this presentation, we introduce our effort in theoretically realizing an attosecond pump-probe scheme applied for two-electron system of helium. In particular, we are looking at channel in which fluorescence signal may contain information on the dynamics evolution of correlated wave packet initiated by absorption of two XUV photons.
