Nuclear spin-dependent interactions: searches for WIMP, axion and topological defect dark matter, and tests of fundamental symmetries
We calculate the proton and neutron spin contributions for nuclei using semi-empirical methods, as well as a novel hybrid ab initio/semi-empirical method, for interpretation of experimental data. We
Nuclear anapole moment and axial neutral current in nuclei
Nuclear anapole moments and axial neutral currents are calculated for a set of nuclei. The accuracy of the leading approximation is studied in detail. The core polarization renormalizing both the
P-and T-violating Schiff moment of the mercury nucleus
The Schiff moment of the 199Hg nucleus was calculated using finite-range P-and T-violating weak nucleon-nucleon interaction. Effects of the core polarization were considered in the framework of RPA


Energy-momentum tensor in quantum field theory
The definition of the energy-momentum tensor as a source current coupled to the background gravitational field receives an important modification in quantum theory. In the path-integral approach, the
Conformal anomaly of (2,0) tensor multiplet in six-dimensions and AdS / CFT correspondence
We compute the conformal anomaly in the free d = 6 superconformal (2,0) tensor multiplet theory on generic curved background. Up to a trivial covariant total-derivative term, it is given by the sum
Stress-tensor trace anomaly in a gravitational metric: General theory, Maxwell field
The renormalization of the vacuum expectation value of the stress-energy tensor of a scalar field propagating in a curved space-time with an arbitrary metric was discussed in a previous paper. A new

Index-free heat kernel coefficients
Using index-free notation, we present the diagonal values of the first five heat kernel coefficients associated with a general Laplace-type operator on a compact Riemannian space without boundary.
Path Integral Measure for Gauge Invariant Fermion Theories
It is shown that the path-integral measure for gauge-invariant fermion theories is not invariant under the ${\ensuremath{\gamma}}_{5}$ transformation and the Jacobian gives rise to an extra phase
