What new physics can we extract from inflation using the ACT DR6 and DESI DR2 Observations?
Sayantan Choudhury, Gulnur Bauyrzhan, Swapnil Kumar Singh +1
We present a comprehensive analysis of inflationary models in light of projected sensitivities from forthcoming CMB and gravitational wave experiments, incorporating data from rece…
Quantum metrology with partially accessible chaotic sensors
Harshita Sharma, Sayan Choudhury, Jayendra N. Bandyopadhyay
Most quantum metrology protocols harness highly entangled probe states and globally accessible measurements to surpass the standard quantum limit. However, it is challenging to sat…
Quintessential Inflation in Light of ACT DR6
Sayantan Choudhury, Swapnil Kumar Singh, Satish Kumar Sahoo
We perform a precision investigation of smooth quintessential inflation in which a single canonical scalar field unifies the two known phases of cosmic acceleration. Using a CMB-no…
Gravitational Wave Signatures of Periodic Motion near Higher-Derivative Einstein-Ãther Black Holes
Sayantan Choudhury, Md Khalid Hossain, Gulnur Bauyrzhan +1
Higher-derivative modifications of general relativity are generically expected from effective field theory approaches to quantum gravity, and they arise naturally in Lorentz-violat…
Stochastic origin of primordial fluctuations in the Sky
Sayantan Choudhury
We provide a study of the effects of the Effective Field Theory (EFT) generalisation of stochastic inflation on the production of primordial black holes (PBHs) in a model-independe…
