We derive the equations of motion for a system undergoing boost-invariant longitudinal and azimuthally-symmetric transverse "Gubser flow" using leading-order anisotropic hydrodynamics. This is accomplished by assuming that the one-particle distribution function is ellipsoidally-symmetric in the momenta conjugate to the de Sitter coordinates used to parameterize the Gubser flow. We then...

The decorrelation of 2nd and 3rd order anisotropic flow along
longitudinal direction with large pseudorapidity η gap is investigated in
event-by-event (3+1)D ideal hydrodynamics with fluctuating initial
conditions from A MultiPhase Transport (AMPT) model. The agreement
between our results and CMS data for all available centralities in Pb+Pb
collisions at LHC suggests that the string...

Thermal fluctuations arising during hydrodynamic evolution of
the system (a.k.a., *hydrodynamic fluctuations*) [1] play an important role
in event-by-event hydrodynamic simulations. For example, entropy
production fluctuates during the expansion even if we start from a common
initial condition in a macroscopic sense [2]. On the other hand, the
effect of the fluctuations must be...

The Beam Energy Scan (BES) at the Relativistic Heavy-Ion Collider was proposed to characterize the properties of the medium produced in heavy-ion interactions over a broad range of baryon chemical potential. The aptitude of the STAR detector for mid-rapidity measurements has previously been leveraged to measure identified particle yields and spectra to extract bulk properties for the BES...

Most studies of anisotropy flow phenomena have assumed a global flow phase angle (or event plane angle) that is boost invariant in pseudorapidity ($\eta$). It was realized in recent years that this assumption may not be valid in presence of initial-state fluctuations, especially along the longitudinal direction. The effect of eta-dependent event plane fluctuations would break the factorization...
