## My Research Activities

Pioneering works which created new fields of research, led to discoveries and new theories.

1. Prediction of million times enhancement of violation of fundamental symmetry (parity P) in neutron-nucleus reactions near p-wave compound resonances. This prediction opened a new area of research and initiated numerous experimental and theoretical studies around the world which lasted for 20 years, with special conferences. This work was awarded the Lenin Komsomol prize.

2. The first theory of the nuclear anapole moment (a magnetic moment violating fundamental symmetries, P and C) and proposals for atomic and molecular experiments which led to the discovery of this moment by the group led by Nobel Laureate C. Wieman. This was the first observation of an electromagnetic moment violating fundamental symmetries and a new method to study parity violating nuclear forces. This discovery is in the history of science. Extensive experimental and theoretical activity on this topic continues around the world.

3. A new very powerful method for the highest precision atomic calculations: perturbation theory in screened electron interaction with all-orders summation of dominating diagrams. Numerous applications.

4. First accurate many-body calculations of violation of fundamental symmetries, Parity (P) and Time reversal (T), which are used for testing unification theories in atomic experiments.

5. Prediction of Fr atom spectra (before measurements) which helped to detect these spectra. Prediction of unknown spectra and probabilities of electromagnetic transitions in unstable and superheavy elements, and in highly charged ions.

6. Definition and first calculations of the nuclear Schiff moments produced by T and P violating nuclear forces, and calculations of atomic electric dipole moments (EDM) produced by these nuclear moments. New method to test unification theories.

7. Prediction of new phenomenon - enhanced collective nuclear moments violating P and T invariance. This prediction motivated a new generation of measurements and calculations of atomic EDMs for testing unification theories.

8. Theoretical discovery and study of chaotic many-electron compound eigenstates in atoms and ions.

9. Statistical theory of finite systems (excited nuclei, atoms, molecules) based on properties of chaotic compound states. This is a new general statistical theory that has a huge number of potential applications including methods to calculate matrix elements and amplitudes between chaotic eigenstates. Specific predictions include the enhancement of weak interactions and effects of violation of the fundamental symmetries, electron recombination and combination (inelastic) photon scattering, and suppression of the photoionization via many-electron resonances. Time-dependent problems such as an increase of entropy, transition to the equilibrium state and (non-exponential) decay of the doorway states have also been considered.

10. Formulae for atomic scattering length and effective range. ¾ of atoms have positive scattering length and stable Bose (or Fermi) condensate, ¼ have unstable condensate. This work is described in textbooks (for example, in the 3rd edition of Theoretical Atomic Physics by H. Friedrich)

11. Theory of the exchange-assisted tunnelling. The exchange interaction and correlations radically change the behaviour of a quantum particle in a classically forbidden region. Instead of the conventional exponential decrease, the electron wave function decreases as r ^{- 2} inside an atom or molecule, and as

r ^{- 3} , r ^{- 3.5} and r ^{- 4} in 1D, 2D and 3D crystals, respectively. An example of the application is the enhanced annihilation of a positron with the inner shell electrons.

12. Proposal of new methods to search for space-time variation of fundamental constants including the Many-Multiplet method in astronomy and comparison of frequencies of two optical clocks in the laboratory. Proposals and calculations of the enhanced effects in atoms, molecules and nuclei. Now, the majority of the precise results in this very popular area of research from Big Bang nucleosynthesis and quasar spectra to atomic clocks are based on our ideas and calculations.

13. Proposals of new atomic clocks of higher projected accuracy and smaller size, including “magic angle” and “micromagic” clocks, highly charged ion clocks, clocks with zero thermal shift, and specific schemes for nuclear clocks. Proposals of the clocks with strongly enhanced sensitivity to the variation of the fundamental constants.

14. First periodic table for a new type of atomic system – positron-atom bound states. Calculations of positron-atom bound states and resonances for all atoms, identification of atoms that can bind positrons.

15. Cosmic sources of violation of the fundamental symmetries, new effects of Dark matter in atoms and pulsars. The suggested effects are linear in a very small constant that quantifies the interaction between dark matter particles and ordinary matter. This gives an enormous advantage. Previously discussed effects are quadratic or quartic.

16. A new method to detect cosmic topological defects using the pulsar timing: the topological defects change the pulsar rotation frequency.

17. Quantum effects create black hole absorption properties before the actual formation of the black hole. Discovery of a dense spectrum of narrow resonances in near-singular metrics. Amazingly, capture of quantum particles to these very-long-lifetime resonances imitates the black hole absorption with the same capture cross section.

18. It is shown that Dark matter may be a source of the space-time variation of the fundamental constants. Using this connection the limits on the quadratic interaction of light Dark matter with photons, nucleons, electrons and Higgs boson have been improved up to 15 orders of magnitude. Limits on interaction of Dark matter with W and Z bosons have been established for the first time.

19. Laboratory limits on the anisotropy of the speed of light (studied in the famous Michelson-Morley experiment) have been improved by 10 orders of magnitude. This anisotropy leads to anisotropy of the Coulomb interaction, which affects atomic spectra.

20. Exponential enhancement of nuclear fusion reactions by condensed matter environment** **(motivated** **by the “cold fusion” accelerator experiments). In the projectile-target collision of light nuclei (e.g. d+d) a half of energy goes to the motion of the centre of mass. If the target nucleus is placed inside a crystal consisting of heavy atoms, after several “preliminary” collisions the momentum of the centre of mass may be transferred to heavy atoms without energy loss, i.e. all the energy goes to the relative motion (the projectile-target case is transformed into the colliding beams case). This increase of the relative velocity exponentially increases the penetration through the Coulomb barrier. Our calculations have shown that the exponential enhancement of the nuclear fusion happens at the energy of the projectile smaller than1 KeV.

21. Extension of the famous Schiff theorem about the screening of the static external electric field in atoms to the cases of an oscillating electric field and oscillating nuclear EDM. Applications include measurability of nuclear electric dipole moments, search for dark matter and effects of atomic electrons on nuclear reactions.

## My Engagement

Member of International Advisory committees for a number of conferences, organiser of session on Variation of the fundamental constants, violation of the fundamental symmetries and dark matter at The Sixteenth Marcel Grossmann Meeting on Recent Developments in Theoretical and Experimental General Relativity, Astrophysics and Relativistic Field Theories (MG16). I also organised such session at MG15, MG14 and MG13 (every three years) and satellite conference on a similar topic at International Conference on Atomic Physics (ICAP22).
