Emergence of Unruh prethermalization for uniformly accelerating many-atom system
Saptarshi Saha, Chiranjeeb Singha, Pragna Das +1
A uniformly accelerated atom in an inertial vacuum generally thermalizes and reaches a Gibbs state. This phenomenon is commonly known as the Unruh effect. Here, we show that the si…
Renormalisable Non-local Quark-Gluon Interaction: Mass Gap, Chiral Symmetry Breaking & Scale Invariance
Arpan Chatterjee, Marco Frasca, Anish Ghoshal +1
We derive a Nambu--Jona-Lasinio (NJL) model from a non-local gauge theory and show that it has confining properties at low energies. In particular, we present an extended approach…
Search for the boson decaying to a right-handed neutrino pair in leptophobic models
Mathew Thomas Arun, Arpan Chatterjee, Tanumoy Mandal +3
The extensions of the Standard Model contain a heavy neutral gauge boson . If leptophobic, the boson can evade the stringent bounds from the dilepton resonance sea…
Can a pure state remain pure in the Unruh effect?
Saptarshi Saha, Arpan Chatterjee, Chiranjeeb Singha
A uniformly accelerated detector in an inertial vacuum undergoes an unavoidable dissipation, and the final steady-state becomes thermal. However, to attain such a mixed state, ther…
Retarded resonance Casimir-Polder interaction of a uniformly rotating two-atom system
Saptarshi Saha, Chiranjeeb Singha, Arpan Chatterjee
We consider here, a two-atom system is uniformly moving through a circular ring at an ultra-relativistic speed and weakly interacting with common external fields. The vacuum fluctu…
How the mass of a scalar field influences Resonance Casimir-Polder interaction in Schwarzschild spacetime
Arpan Chatterjee, Saptarshi Saha, Chiranjeeb Singha
\emph{Resonance Casimir-Polder interaction(RCPI)} occurs in nature when one or more atoms are in their excited states and the exchange of real photon is involved between them due t…
Mining for Causal Relationships: A Data-Driven Study of the Islamic State
Andrew Stanton, Amanda Thart, Ashish Jain +3
The Islamic State of Iraq and al-Sham (ISIS) is a dominant insurgent group operating in Iraq and Syria that rose to prominence when it took over Mosul in June, 2014. In this paper,…
