Momentum Dependence of Heavy Quark Diffusion in a Thermal Gluonic Plasma on the Lattice
Harshit Pandey, Sayantan Sharma
We study the dynamics of a heavy quark in a thermal plasma consisting of non-perturbatively interacting soft momentum gluons at high temperatures, described in terms of an effectiv…
Imprints of chiral anomaly and disorder in the Dirac eigenspectrum of QCD at finite temperature
Ravi Shanker, Harshit Pandey, Sayantan Sharma
We perform a comprehensive study of the properties of Dirac eigenvalue spectrum in QCD as a function of temperature on the lattice. In addition to effects due to interplay between…
Revisiting the sphaleron and axion production rates in QCD at high temperatures
Sayak Guin, Sayantan Sharma
We report our new lattice results for the sphaleron rate calculated within a thermal effective field theory of soft SU(N) gluons whose momenta are below the magnetic scale, where $…
Anomalous Chiral Anomaly in Spin-1 Fermionic Systems
Shantonu Mukherjee, Sayantan Sharma, Hridis K. Pal
Chiral anomaly is a key feature of Lorentz-invariant quantum field theories: in presence of parallel external electric and magnetic fields, the number of massless Weyl fermions of…
Mean free path of photons in relativistic heavy ion collisions
Jajati K. Nayak, Rupa Chatterjee
Electromagnetic probes, such as photons and dileptons, play a key role in diagnosing the initial temperature of the hot and dense quark-gluon plasma (QGP) matter created in relativ…
Aspects of the chiral crossover transition in (2+1)-flavor QCD with Möbius domain-wall fermions
Rajiv V. Gavai, Mischa E. Jaensch, Olaf Kaczmarek +6
The non-singlet part of the chiral symmetry in QCD with two light flavors is known to be restored through a crossover transition at a pseudo-critical temperature. However, the temp…
