Liouville theory beyond the cosmological horizon
Geoffrey Compère, Laura Donnay, Pierre-Henry Lambert +1
The dS/CFT correspondence postulates the existence of a Euclidean CFT dual to a suitable gravity theory with Dirichlet boundary conditions asymptotic to de Sitter spacetime. A semi…
The Algebra of Diffeomorphisms from the World Sheet
Waldemar Schulgin, Jan Troost
The quantum theory of a massless spin two particle is strongly constrained by diffeomorphism invariance, which is in turn implied by unitarity. We explicitly exhibit the space-time…
Asymptotic symmetry groups and operator algebras
Waldemar Schulgin, Jan Troost
We associate vertex operators to space-time diffeomorphisms in flat space string theory, and compute their algebra, which is a diffeomorphism algebra with higher derivative correct…
Three-BMN Correlation Functions: Integrability vs. String Field Theory One-Loop Mismatch
Waldemar Schulgin, A. V. Zayakin
We compare calculations of the three-point correlation functions of BMN operators at the one-loop (next-to-leading) order in the scalar SU(2) sector from the integrability expressi…
Boundary Terms, Spinors and Kerr/CFT
Melanie Becker, Waldemar Schulgin
Similarly as in AdS/CFT, the requirement that the action for spinors be stationary for solutions to the Dirac equation with fixed boundary conditions determines the form of the bou…
The heterotic string at high temperature (or with strong supersymmetry breaking)
Waldemar Schulgin, Jan Troost
Perturbative heterotic string theory develops a single complex tachyonic mode beyond the Hagedorn temperature. We calculate the quartic effective potential for this tachyonic mode…
