Stationary Couette-type flows in relativistic fluids
Lorenzo Gavassino, Patrick Niekamp, Sören Schlichting +1
We investigate a class of stationary, planar-symmetric solutions of relativistic hydrodynamics, in which a dissipative fluid is confined between two parallel plates that move relat…
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…
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.…
Universality of scaled particle spectra in ultrarelativistic heavy-ion collisions
Cicero D. Muncinelli, Fernando G. Gardim, David D. Chinellato +7
We study the transverse momentum spectra of identified particles in ultrarelativistic collisions of large and small collision systems. In order to isolate information contained in…
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…
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…
Relativistic Dissipative Magnetohydrodynamics from the Boltzmann equation for a two-component gas
Khwahish Kushwah, Gabriel S. Denicol
We derive the equations of motion of relativistic magnetohydrodynamics, as well as microscopic expressions for all of its transport coefficients, from the Boltzmann equation using…
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…
Causality violations in simulations of large and small heavy-ion collisions
Renata Krupczak, Tiago Nunes da Silva, Thiago S. Domingues +9
Heavy-ion collisions, such as Pb-Pb or p-Pb, produce extreme conditions in temperature and density that make the hadronic matter transition to a new state, called quark-gluon plasm…
Hydrodynamic theories for a system of weakly self-interacting classical ultra-relativistic scalar particles: microscopic derivations and attractors
Gabriel S. Rocha, Caio V. P. de Brito, Gabriel S. Denicol
We derive and investigate several hydrodynamic formalisms that emerge from a system of classical, ultra-relativistic scalar particles self-interacting via a quartic potential. The…
Temperature and Strong Magnetic Field Effects in Dense Matter
J. Peterson, P. Costa, R. Kumar +3
We study consistently the effects of magnetic field on hot and dense matter. In particular, we look for differences that arise due to assumptions that reproduce the conditions prod…
Pre-hydrodynamic evolution in large and small systems
Tiago Nunes da Silva, David D. Chinellato, André V. Giannini +6
We extend our previous investigation of the effects of pre-hydrodynamic evolution on final-state observables in heavy-ion collisions to smaller systems. We use a state-of-the-art h…
Perspectives on few-body cluster structures in exotic nuclei
D. Bazin, K. Becker, F. Bonaiti +16
It is a fascinating phenomenon in nuclear physics that states with a pronounced few-body structure can emerge from the complex dynamics of many nucleons. Such halo or cluster state…

We analytically determine all the eigenvalues and eigenfunctions of the linearized Boltzmann collision operator in massless scalar theory in the high-temperature (classical)…
Perturbative approaches in relativistic kinetic theory and the emergence of first-order hydrodynamics
Gabriel S. Rocha, Gabriel S. Denicol, Jorge Noronha
Hydrodynamics can be formulated in terms of a perturbative series in derivatives of the temperature, chemical potential, and flow velocity around an equilibrium state. Different fo…
Assessing the ultracentral flow puzzle in hydrodynamic modeling of heavy-ion collisions
A. V. Giannini, M. N. Ferreira, M. Hippert +6
An outstanding problem in heavy-ion collisions is the inability for models to accurately describe ultra-central experimental flow data, despite that being precisely the regime wher…
Transport coefficients of quasi-particle models within a new relaxation time approximation of the Boltzmann equation
Gabriel S. Rocha, Maurício N. Ferreira, Gabriel S. Denicol +1
We investigate the transport properties of a kinetic theory model that is tuned to describe the thermodynamic properties of QCD at zero chemical potential using a new formulation o…

S. Burrello, S. Calabrese, F. Cappuzzello +43
Charge exchange (CE) reactions offer a major opportunity to excite nuclear isovector modes, providing clues about the nuclear interaction in the medium. Moreover, double charge exc…
