Green, I developed the boundary state description of
in the light cone gauge
constructed D-instantons in type IIB superstring theory,
instanton induced terms in the effective action like R^4 and
the exact form of these terms using S-duality
with M.Costa and A. Strominger, I found new
solutions which generalize the Melvin solution of
theory and give interpolations between supersymmetric and
|S-branes and time
dependent backgrounds in String theory
Strominger, I found new time dependend solutions
creation and decay of branes.
|Together with D. Bak and S.
Hirano I found a dilatonic domain wall solution in AdS_5 x
corresponds to an interface solution in N=4 SYM where the
constant jumps across the interface
interfaces and junctions
with E. D'Hoker, J. Estes, D. Krym and M. Chiodaroli, I
generalizations of the Janus solutions in type IIB string
M-theory. These solutions preserve up to half the original
supersymmetry and are dual to interfaces and junctions of
Holes in Higher Spin gravity
|Together with P. Kraus, E.
Perlmutter and M. Ammon constructed black hole solutions in
dimensional higher spin theories which are described by
theories in the bulk.
|Entanglement entropy with Wilson
loop and surfaces
|Together with Simon Gentle we calculated the
holographic entanglement entropy of the bubbling
supergravity solutions describing Wilson loops with
representations of order N^2.
