The oxic-anoxic transition zone (OATZ) of freshwater sediments, where opposing gradients exist of reduced iron and sulfide with oxygen, creates a suitable environment for microorganisms that derive...
Bergshoeff, E. A., Hartong, J., Ploegh, A., Sorokin, D.
We construct the half-supersymmetric instanton solutions that are electric-magnetically dual to the recently discussed half-supersymmetric Q7-branes. We call these instantons `Q-instantons'. Whereas...

Q-branes in type IIB supergravity (2008)
Bergshoeff, E.A., Hartong, J., Sorokin, D.
The notion of Q7-branes and Q-instantons is introduced. These are one-half BPS solutions of the type IIB supergravity theory characterized by a set of three parameters p, q, r such that r^2 > 4pq....
Dynamics of Higher Spin Fields and Tensorial Space (2005)
Bandos, I., Bekaert, X., De Azcarraga, J. A., Sorokin, D., Tsulaia, M.
The structure and the dynamics of massless higher spin fields in various dimensions are reviewed with an emphasis on conformally invariant higher spin fields. We show that in D=3,4,6 and 10...
Sorokin, D., Tourova, T., Schmid, M.C., Wagner, M., Koops, H.P., Kuenen, J.G., ...
Five mixed samples prepared from the surface sediments of 20 north-east Mongolian soda lakes with total salt contents from 5 to 360 g/l and pH values from 9.7 to 10.5 were used to enrich for...
N=4 Superconformal Mechanics and the Potential Structure of AdS Spaces (2000)
Donets, E. E., Pashnev, A., Rivelles, V. O., Sorokin, D., Tsulaia, M.
The dynamics of an N=4 spinning particle in a curved background is described using the N=4 superfield formalism. The $SU(2)_{local}\times SU(2)_{global}$ N=4 superconformal symmetry of the particle...
The M5-brane Hamiltonian (1998)
Bergshoeff, E., Sorokin, D., Townsend, P. K.
We obtain the Hamiltonian form of the worldvolume action for the M5-brane in a general D=11 supergravity background. We use this result to obtain a new version of the covariant M5-brane Lagrangian in...

NOTE ON MANIFEST LORENTZ AND GENERAL COORDINATE INVARIANCE IN DUALITY SYMMETRIC MODELS. (1995)
Pasti, P., Sorokin, D., Tonin, M.
We consider a generalization of a duality symmetric model proposed by Schwarz and Sen. It is based on enlarging the model with a dynamical vector field being a time-like component of a local Lorentz...
TWISTOR-LIKE SUPERPARTICLES REVISITED. (1995)
Bandos, I., Nurmagambetov, A., Sorokin, D., Volkov, D.
We consider a formulation of N=1 D=3,4 and 6 superparticle mechanics, which is manifestly supersymmetric on the worldline and in the target superspace. For the construction of the action we use only...
SUPERSTRINGS AND SUPERMEMBRANES IN THE DOUBLY SUPERSYMMETRIC GEOMETRICAL APPROACH (1995)
Bandos, I., Pasti, P., Sorokin, D., Tonin, M., Volkov, D.
We perform a generalization of the geometrical approach to describing extended objects for studying the doubly supersymmetric twistor--like formulation of super--p--branes. Some basic features of...
On the Chiral Fermions in the Twistor--Like Formulation of D=10 Heterotic String (1993)
An n=8 worldsheet superfield action is proposed for describing chiral fermions in the twistor-like formulation of an N=1, D=10 heterotic superstring.
