Graviton-mediated entanglement due to light bending from a quantum rotor
Dripto Biswas, Sougato Bose, Anupam Mazumdar +1
One of the key tests of the quantum nature of gravity is to test whether the virtual mediator of gravity between matter and photon gives rise to the quantum light-bending phenomeno…
The Spectrum-generating Algebra for Bosonic Strings in a Linear Dilaton Background
Dripto Biswas
We extend the systematic construction of bosonic DDF operators to the light-like linear dilaton background to investigate how higher-spin string states behave beyond flat spacetime…
DDF amplitudes are lightcone amplitudes and the naturalness of Mandelstam map
Dripto Biswas, Igor Pesando
We show that on shell DDF amplitudes are on shell lightcone amplitudes and that Mandelstam maps emerge naturally with a precise normalization and are intrinsic to the DDF states. O…
The Reggeon Vertex for DDF States
Dripto Biswas, Raffaele Marotta, Igor Pesando
We provide a compact expression for the generating function of correlators involving an arbitrary number of bosonic open string DDF states. The explicit correlators for DDF sta…
Framed DDF operators and the general solution to Virasoro constraints
Dripto Biswas, Igor Pesando
We define the framed DDF operators by introducing the concept of local frames in the usual formulation of DDF operators. In doing so it is possible to completely decouple the DDF o…
Gravitational Optomechanics: Photon-Matter Entanglement via Graviton Exchange
Dripto Biswas, Sougato Bose, Anupam Mazumdar +1
The deflection of light in the gravitational field of the Sun is one of the most fundamental consequences for general relativity as well as one of its classical tests first perform…
