Transport-based initial conditions for heavy-ion collisions at finite densities
H. Roch, G. Pihan, A. Monnai +53
We employ the SMASH transport model to provide event-by-event initial conditions for the energy-momentum tensor and conserved charge currents in hydrodynamic simulations of relativ…
Charm quark evolution in the early stages of heavy-ion collisions
Mayank Singh, Manu Kurian, Björn Schenke +2
Heavy quarks are predominantly generated at the initial stage of relativistic heavy-ion collisions such that heavy flavor observables have the potential to provide information on t…
Acausality-driven instabilities in transient relativistic viscous hydrodynamics
Lorenzo Gavassino, Henry Hirvonen, Jean-François Paquet +2
We investigate non-linear instabilities stemming from superluminal propagation of information in Israel-Stewart-like models of relativistic viscous fluid dynamics. In relativity, t…
Nonlinear causality of Israel-Stewart theory with diffusion
Ian Cordeiro, Fábio S. Bemfica, Enrico Speranza +1
We present the first fully nonlinear causality constraints in dimensions for Israel-Stewart theory in the presence of energy and number diffusion in the Eckart and Land…
Shell effects in quasi-fission for calcium induced reactions forming thorium isotopes
C. Simenel, A. S. Umar, K. Godbey +1
Quantum shell effects induce an asymmetric fission mode in actinides, which disappears in neutron deficient isotopes. Quasi-fission, characterized by a significant mass transfer in…
Perfect spinfluid: A divergence-type approach
Nick Abboud, Lorenzo Gavassino, Rajeev Singh +1
We present a new formulation of non-dissipative relativistic spin hydrodynamics that incorporates spin degrees of freedom into the divergence-type theory framework. Due to the dive…
Relaxation Time Approximation for a multi-species relativistic gas
Gabriel S. Rocha, Gabriel S. Denicol
We generalize a recent prescription for the relaxation time approximation for the relativistic Boltzmann equation for systems with multiple particle species at finite temperature.…
Causality constraints on radiative transfer
Lorenzo Gavassino
The standard formula, due to Spiegel, for the smoothing of temperature fluctuations by radiative transfer is unstable in relativity. This is due to the fact that Spiegel neglected…
Pauli energy contribution to nucleus-nucleus interaction
A. S. Umar, K. Godbey, C. Simenel
The investigation delves into understanding how the Pauli exclusion principle influences the bare potential between atomic nuclei through the application of advanced theoretical me…
Convergence of the hydrodynamic gradient expansion in relativistic kinetic theory
Lorenzo Gavassino
We rigorously prove that, in any relativistic kinetic theory whose non-hydrodynamic sector has a finite gap, the Taylor series of all hydrodynamic dispersion relations has a finite…
Modelling stochastic fluctuations in relativistic kinetic theory
Gabriel Soares Rocha, Lorenzo Gavassino, Nicki Mullins
Using the information current, we develop a Lorentz-covariant framework for modeling equilibrium fluctuations in relativistic kinetic theory in the grand-canonical ensemble. The re…
Gapless non-hydrodynamic modes in relativistic kinetic theory
Lorenzo Gavassino
We provide rigorous criteria to determine whether the non-hydrodynamic sector of a relativistic kinetic theory is gapless. These general criteria apply to both Boltzmann's equation…
Branch-cut in the shear-stress response function of massless with Boltzmann statistics
Gabriel S. Rocha, Isabella Danhoni, Kevin Ingles +2
Using an analytical result for the eigensystem of the linearized collision term for a classical system of massless scalar particles with quartic self-interactions, we show that the…
Infinite Order Hydrodynamics: An Analytical Example
Lorenzo Gavassino
We construct a kinetic model for matter-radiation interactions whose hydrodynamic gradient expansion can be computed analytically up to infinite order in derivatives, in the fully…
Transport coefficients of transient hydrodynamics for the hadron-resonance gas and thermal-mass quasiparticle models
Gabriel S. Rocha, Gabriel S. Denicol
We calculate all transport coefficients of second order transient hydrodynamics in two effective kinetic theory models: a hadron-resonance gas and a quasiparticle model with therma…
Consistent inclusion of fluctuations in first-order causal and stable relativistic hydrodynamics
Lorenzo Gavassino, Nicki Mullins, Mauricio Hippert
We construct, for the first time, a Bemfica-Disconzi-Noronha-Kovtun (BDNK) theory for linear stochastic fluctuations, which is proved to be mathematically consistent, causal, and c…
First-order relativistic hydrodynamics with an information current
Lorenzo Gavassino, Nick Abboud, Enrico Speranza +1
We show that it is possible to define a timelike future-directed information current within relativistic first-order hydrodynamics. This constitutes the first step toward a covaria…
Relativistic heat conduction in the large-flux regime
Lorenzo Gavassino
We propose a general procedure for evaluating, directly from microphysics, the constitutive relations of heat-conducting fluids in regimes of large fluxes of heat. Our choice of hy…
Theories of Relativistic Dissipative Fluid Dynamics
Gabriel S. Rocha, David Wagner, Gabriel S. Denicol +2
Relativistic dissipative fluid dynamics finds widespread applications in high-energy nuclear physics and astrophysics. However, formulating a causal and stable theory of relativist…
Mapping GENERIC hydrodynamics into Carter's multifluid theory
Lorenzo Gavassino
We show that the GENERIC model for relativistic heat conduction is a multifluid of Carter. This allows one to compute the multifluid constitutive relations directly from the GENERI…
Applications of emulation and Bayesian methods in heavy-ion physics
Jean-François Paquet
Heavy-ion collisions provide a window into the properties of many-body systems of deconfined quarks and gluons. Understanding the collective properties of quarks and gluons is poss…

We obtain stability criteria for diffusive inviscid multicomponent Israel-Stewart hydrodynamics with and without background or dynamic electromagnetic fields. Our analysis is groun…
Early-times Yang-Mills dynamics and the characterization of strongly interacting matter with statistical learning
Matthew R. Heffernan, Charles Gale, Sangyong Jeon +1
In ultrarelativistic heavy-ion collisions, a plasma of deconfined quarks and gluons is formed within fm/c of the nuclei's impact. The complex dynamics of the collision before $…
