What it’s like for a renter - a personal perspective of the housing crisis

|
By Nayan Das
| The Fifth Estate Verified
At one of the apartments that Nayan Das visited in the hope of finding another relatively short term home, having pretty much given up on owning a home, he met another prospective tenant who seemed a bit panicked. She had just a week to go before being officially homeless. Should he give up his application in her favour? “If people cannot be pragmatically optimistic, then being a pessimist is not bad either.

Light Dirac neutrino portal dark matter with gauged $U(1{)}_{B\ensuremath{-}L}$ symmetry

|
By Nayan Das, Debasish Borah
| Physical Review B
We propose a gauged U(1)B−L version of the light Dirac neutrino portal dark matter. The U(1)B−L symmetry provides a UV completion by naturally accommodating three right-handed neutrinos from anomaly cancellation requirements which, in combination with the left-handed neutrinos, form the sub-eV Dirac neutrinos after electroweak symmetry breaking.

Thermalized dark radiation in the presence of a PBH: $\mathrm{\ensuremath{\Delta}}{\mathrm{N}}_{\mathrm{eff}}$ and gravitational waves complementarity

|
By Nayan Das, Suruj Jyoti Das, Debasish Borah
| Physical Review B
We study the possibility of detecting dark radiation (DR) produced by a combination of interactions with the thermal bath and ultralight primordial black hole (PBH) evaporation in the early Universe. We show that the detection prospects via cosmic microwave background (CMB) measurements of the effective relativistic degrees of freedom ΔNeff get enhanced in some part of the parameter space compared to the purely nonthermal case where DR is produced solely from a PBH.
