The phase diagram of QCD at small chemical potentials
Sourendu Gupta
We investigate the phase diagram of QCD at small chemical potentials, ie, when chiral and flavour symmetry breaking involves the pairing of a quark and an antiquark. The phase diag…
Renormalized Polyakov loops in many representations
Sourendu Gupta, Kay Hubner, Olaf Kaczmarek
We present a renormalization procedure for Polyakov loops which explicitly implements the fact that the renormalization constant depends only on the ultraviolet cutoff. Using this…
Renormalization of Polyakov loops in fundamental and higher representations
Olaf Kaczmarek, Sourendu Gupta, Kay Hubner
We compare two renormalization procedures, one based on the short distance behavior of heavy quark-antiquark free energies and the other by using bare Polyakov loops at different t…
A systematic expansion for relativistic causal hydrodynamics
Sourendu Gupta
A systematic expansion of the Boltzmann equation for the diffusion of dilute tracers, in powers of the Knudsen number, carried out to next-to-leading order (NLO), gives the relativ…
Aspects of causal viscous hydrodynamics
R. S. Bhalerao, Sourendu Gupta
We investigate the phenomenology of freely expanding fluids, with different material properties, evolving through the Israel-Stewart (IS) causal viscous hydrodynamics, and compare…
