Relativistic spin hydrodynamics with torsion and linear response theory for spin relaxation [PDF]
Journal of High Energy Physics, 2021 Using the second law of local thermodynamics and the first-order Palatini formalism, we formulate relativistic spin hydrodynamics for quantum field theories with Dirac fermions, such as QED and QCD, in a torsionful curved background.

Biophysical Journal, 2014 Following recent observations of large scale correlated motion of chromatin inside the nuclei of live differentiated cells, we present a hydrodynamic theory-the two-fluid model-in which the content of a nucleus is described as a chromatin solution with the nucleoplasm playing the role of the solvent and the chromatin fiber that of a solute. This system

Physical Review Research, 2020 We introduce new classes of hydrodynamic theories inspired by the recently discovered fracton phases of quantum matter. Fracton phases are characterized by elementary excitations (fractons) with restricted mobility. The hydrodynamic theories we introduce

Improving rowing performance by adjusting oar blade size and angle
Frontiers in Sports and Active Living, 2023 The principal aim of the work presented here is to investigate and demonstrate that a forward tilted rowing blade would result in a more efficient and effective motion of the blade through the water that would result in a higher boat speed when an equal ...

Hydrodynamics of weak integrability breaking [PDF]
Journal of Statistical Mechanics: Theory and Experiment, 2021 We review recent progress in understanding nearly integrable models within the framework of generalized hydrodynamics (GHD). Integrable systems have infinitely many conserved quantities and stable quasiparticle excitations: when integrability is broken ...

Settling slurry flow near deposition velocity in inclined pipe of negative slope [PDF]
EPJ Web of Conferences, 2019 Pipe flow of sand-water slurry (settling slurry) is sensitive to pipe inclination. The effect of the angle to which the partially stratified flow is inclined from the horizontal has been subject to investigation in numerous studies.

The hydrodynamics of swimming microorganisms [PDF]
, 2008 Cell motility in viscous fluids is ubiquitous and affects many biological processes, including reproduction, infection and the marine life ecosystem. Here we review the biophysical and mechanical principles of locomotion at the small scales relevant to ...

Cosmological smoothed particle hydrodynamics simulations: a hybrid multiphase model for star formation [PDF]
, 2002 We present a model for star formation and supernova feedback that describes the multiphase structure of star-forming gas on scales that are typically not resolved in cosmological simulations.

Hydrodynamics of spin currents [PDF]
, 2021 We study relativistic hydrodynamics in the presence of a non vanishing spin potential. Using a variety of techniques we carry out an exhaustive analysis, and identify the constitutive relations for the stress tensor and spin current in such a setup ...

Physical Review Letters, 2013 We report the experimental observation of multi-bound-soliton solutions of the nonlinear Schrodinger equation (NLS) in the context of hydrodynamic surface gravity waves. Higher-order N-soliton solutions with N = 2, 3 are studied in detail and shown to be associated with self-focusing in the wave group dynamics and the generation of a steep localized ...
