Amplified transduction of Planck-scale effects using quantum optics
Pasquale Bosso, Saurya Das, Igor Pikovski +1
The unification of quantum mechanics and gravity remains as one of the primary challenges of present-day physics. Quantum-gravity-inspired phenomenological models offer a window to…
The central role of symmetry in physics
Saurya Das, Gabor Kunstatter
Spacetime and internal symmetries can be used to severely restrict the form of the equations for the fundamental laws of physics. The success of this approach in the context of gen…
Bilocal theory and gravity I
Pablo Diaz, Saurya Das, Mark Walton
With the aim of investigating the relation between gravity and non-locality at the classical level, we study a bilocal scalar field model. Bilocality introduces new (internal) degr…
Generalized Uncertainty Principle and Angular Momentum
Pasquale Bosso, Saurya Das
Various models of quantum gravity suggest a modification of the Heisenberg's Uncertainty Principle, to the so-called Generalized Uncertainty Principle, between position and momentu…
Stringent theoretical and experimental bounds on graviton mass
Ahmed Farag Ali, Saurya Das
We show from theoretical considerations, that if the graviton is massive, its mass is constrained to be about . This estimate is consistent with those obtained fro…
Discreteness of Space from GUP in a Weak Gravitational Field
Soumen Deb, Saurya Das, Elias C. Vagenas
Quantum gravity effects modify the Heisenberg's uncertainty principle to a generalized uncertainty principle (GUP). Earlier work showed that the GUP-induced corrections to the Schr…
