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…
Pulsating strings in I-brane background
Sagar Biswas, Nibedita Padhi, Kamal L Panigrahi
We study pulsating strings both on a single stack of NS5-branes and two orthogonal stacks of NS5-branes (the so called I-brane) by using the Polyakov form of the fundamental string…
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…
Holographic entanglement entropy for relativistic hydrodynamic flows
Jyotirmoy Bhattacharya, Parthajit Biswas, A. Chandranathan +1
We study the behaviour of holographic entanglement entropy (HEE) in near equilibrium thermal states which are macroscopically described by conformal relativistic hydrodynamic flows…
Out-of-Time-Order correlators in driven conformal field theories
Suchetan Das, Bobby Ezhuthachan, Arnab Kundu +3
We compute Out-of-Time-Order correlators (OTOCs) for conformal field theories (CFTs) subjected to either continuous or discrete periodic drive protocols. This is achieved by an app…
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…
