Quantum-Gravitational Backreaction in the BTZ Background from Curved Momentum Space
Partha Nandi, Mainak Roy, Langa Horoto +2
We explore how quantum properties of spacetime, specifically the curvature of momentum space, can backreact on classical gravity within a tractable semiclassical (2+1)-dimensional…
Fate of -Minkowski space-time in non-relativistic (Galilean) and ultra-relativistic (Carrollian) regimes
Deeponjit Bose, Anwesha Chakraborty, Biswajit Chakraborty
Here, we present an algebraic and kinematical analysis of non-commutative -Minkowski spaces within Galilean (non-relativistic) and Carrollian (ultra-relativistic) regimes. Utili…
Symmetries of Minkowski space-time: A possibility of exotic momentum space geometry?
Partha Nandi, Anwesha Chakraborty, Sayan Kumar Pal +2
The quest for a quantum gravity phenomenology has inspired a quantum notion of space-time, which motivates us to study the fate of the relativistic symmetries of a particular model…
Our Trysts with `Bal' and Noncommutative Geometry
Biswajit Chakraborty, Partha Nandi, Sayan Kumar Pal +1
This contributory article begins with our fond and sincere reminiscences about our beloved Prof. A.P. Balachandran. In the main part, we discuss our recent formulation of quantum m…
Spectral triple with real structure on fuzzy sphere
Anwesha Chakraborty, Partha Nandi, Biswajit Chakraborty
Here we have illustrated the construction of a real structure on fuzzy sphere in its spin-1/2 representation. Considering the SU(2) covariant Dirac and chirality operator o…
Fingerprints of the quantum space-time in time-dependent quantum mechanics: An emergent geometric phase
Anwesha Chakraborty, Partha Nandi, Biswajit Chakraborty
We show the emergence of Berry phase in a forced harmonic oscillator system placed in the quantum space-time of Moyal type, where the time 't' is also an operator. An effective com…
