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…

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…
