DBI Action from Closed Strings and D-brane second Quantization
Brane-like vertex operators play an important role in a worldsheet
formulation of D-branes and M-theory. In this paper we derive the DBI D-brane
action from NSR closed string sigma-model with brane-like states. We also show
that these operators carry RR charges and define D-brane wavefunctions in a
second quantized formalism.Comment: 16 pages, latex, typos corrected, BRST nontriviality condition (9)

Generalization of Schensted insertion algorithm to the cases of hooks and semi-shuffles
Given an rc-graph of permutation and an rc-graph of permutation
, we provide an insertion algorithm, which defines an rc-graph in the case when is a shuffle with the descent at and has no
descents greater than or in the case when is a shuffle, whose shape is
a hook. This algorithm gives a combinatorial rule for computing the generalized
Littlewood-Richardson coefficients in the two cases mentioned
above.Comment: 22 page
RKKY interaction in graphene at finite temperature
In our publication from 8 years ago (Phys. Rev. B {\bf 84}, 115119 (2011)) we
calculated RKKY interaction between two magnetic impurities adsorbed on
graphene at zero temperature. We show in this short paper that the approach
based on Matsubara formalism and perturbation theory for the thermodynamic
potential in the imaginary time and coordinate representation which was used
then, can be easily generalized, and calculate RKKY interaction between the
magnetic impurities at finite temperature.Comment: LaTex, 4 pages. arXiv admin note: text overlap with arXiv:1108.130
Lift force due to odd (Hall) viscosity
We study the problem of flow of a neutral gas past an infinite cylinder at
right angle to its axis at low Reynolds number when the fluid is characterized
by broken time-reversal invariance, and hence by odd viscosity in addition to
the normal even one. We solve the Oseen approximation to Navier-Stokes equation
and calculate the lift force which appears due to the odd viscosity.Comment: LaTeX, 4 pages. As accepted for publication in PRE. arXiv admin note:
