Extended relaxation time approximation and relativistic dissipative hydrodynamics

“…In the following, we will refer to the Anderson-Witting model as the relaxation-time approximation (RTA). Despite its simplistic nature, RTA and its variations have proven to be immensely useful and have been extensively employed in formulating relativistic dissipative hydrodynamics as well as in deriving transport coefficients [12][13][14][15][16][17][18][19][20][21]. Recently, it has also been applied to study the domain of applicability of hydrodynamics [22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39].…”
