Quantum corrections to spinning superstrings in AdS_3 x S^3 x M^4: determining the dressing phase

M. Beccaria, F. Levkovich-Maslyuk, G. Macorini +1

We study the leading quantum string correction to the dressing phase in the asymptotic Bethe Ansatz system for superstring in AdS_3 x S^3 x T^4 supported by RR flux. We find that t…

Three and Four Point Functions of Stress Energy Tensors in D=3 for the Analysis of Cosmological Non-Gaussianities

Claudio Coriano, Luigi Delle Rose, Mirko Serino

We compute the correlation functions of 3 and 4 stress energy tensors $(T)$ in D=3 in free field theories of scalars, abelian gauge fields, and fermions, which are relevant in the…

Semiclassical energy of the $A d S_{4} \times CP^{3}$ folded string

Matteo Beccaria, Guido Macorini, CarloAlberto Ratti +1

We consider the classical solution describing a folded type IIA string in the background $A d S_{4} \times CP^{3}$ . The string is spinning in $A d S$ and has angular momentum in $…

Graviton Vertices and the Mapping of Anomalous Correlators to Momentum Space for a General Conformal Field Theory

Claudio Coriano, Luigi Delle Rose, Emil Mottola +1

We investigate the mapping of conformal correlators and of their anomalies from configuration to momentum space for general dimensions, focusing on the anomalous correlators $T O O$ ,…

"Short" spinning strings and structure of quantum AdS_5 x S^5 spectrum

M. Beccaria, S. Giombi, G. Macorini +2

Using information from the marginality conditions of vertex operators for the AdS_5 x S^5 superstring, we determine the structure of the dependence of the energy of quantum string…

Leading quantum correction to energy of "short" spiky strings

Matteo Beccaria, CarloAlberto Ratti, Arkady A. Tseytlin

We consider semiclassical quantization of spiky strings spinning in AdS_3 part of AdS_5 X S^5 using integrability-based (algebraic curve) method. In the "short string" (small spin)…

Matrix representation of the time operator

Carl M. Bender, M. Gianfreda

In quantum mechanics the time operator $Θ$ satisfies the commutation relation $[Θ, H] = i$ , and thus it may be thought of as being canonically conjugate to the Hamiltonian $H$ . The ti…

Resummation of semiclassical short folded string

Matteo Beccaria, Guido Macorini

We reconsider semiclassical quantization of folded string spinning in AdS_3 part of AdS_5 X S^5 using integrability-based (algebraic curve) method. We focus on the "short string" (…
