- RESEARCH INTERESTS:
- Methods for precise calculations of
correlation structure of molecules with heavy atoms.
- Relativistic effective core potential (pseudopotential).
- Basis sets for correlation calculations.
- Convergence improvement and intruder state problem in
coupled-cluster calculations.
- MAIN ACHIEVEMENTS:
- Generalized Relativistic Effective Core Potentials (GRECPs)
for the atoms Hg through Rn were generated
[Tupitsyn:1995, Mosyagin:1997] which
accuracy was up to one order of magnitude higher than that
of other tested RECPs with the same number of explicitly
treated electrons in carried out test calculations
[Mosyagin:1997, Mosyagin:2000, Isaev:2000].
Then, the other developments in the GRECP generation were
suggested, which allow one to simulate the Breit interaction
and Fermi nuclear charge distribution
[Petrov:2004, Isaev:2005] as well as
the correlations with the core electrons excluded from
the GRECP calculations
[Mosyagin:2005] by economic way but with very
high precision. The generated potentials were used in
precise calculations of the spectroscopic constants for
the TlH [Titov:2001], HgH [Mosyagin-JCP:2001]
and E112H [Mosyagin-JCP:2006] molecules.
- The optimal GRECP versions for the Ba, Yb, Tl, Pb, I, Hf,
and Xe atoms were generated and employed for calculations
of the P,T-odd parameters for the BaF, YbF, TlF,
PbO*, HI+,
HfF+ molecules [Titov-PRL:1996, Kozlov:1997,
Mosyagin-JPB:1998, Petrov:2002, Isaev-PRA:2004, Petrov:2005,
Petrov-PRA:2007] and the Xe clusters
[Isaev:2007] which are necessary to interpret the results of
fundamental experiments carried out in search of parity (P)
and time-reversal (T) invariance violation and to plan
a new generation of such experiments.
- A new procedure for the correlation basis set generation was
proposed [Mosyagin:2000, Mosyagin-JCP:2001].
This procedure allows one to generate
"equivalent" basis sets for the RECP (two-component) and the
all-electron (four-component) calculations and to
control efficiently the quality of the basis sets in
description of correlations in different space regions.
Moreover, the counterpoise corrections for these basis sets
are practically undependent on some particular selection of
the different valence atomic states for their calculations.
- A new iteration scheme for coupled-cluster (CC) calculations
was proposed [Mosyagin-JPB:2001]
which improves significantly convergence
of CC iterations and thus, solves partly the intruder state
problem.
