Nonequilibrium corrections to conserved Ising criticality in scalar active matter: Ward identities, spectrum, and long crossovers
Piotr Zdybel
We identify the slowest-decaying nonequilibrium perturbations near the three-dimensional conserved Ising critical point and determine their impact on finite-size observables. We st…
Exact solution for the motion of a rigid particle with and symmetry settling under gravity in a viscous fluid
Piotr Zdybel, Maria L. Ekiel-Jeżewska
We provide an exact and complete solution for the dynamics of a rigid particle of uniform density with and symmetry, settling under gravity in a viscous fluid at a R…
Experimental and numerical study of the dynamics of sedimenting pairs of semi-flexible fibers close to attractive `aligned' relative configuration
Harish N. Mirajkar, Chandra Shekhar, Yevgen Melikhov +2
Dynamics of two short semi-flexible fibers settling under gravity in a viscous fluid are investigated at Reynolds numbers Re << 1. We focus on fibers initially relatively close to…
Sedimenting rigid particles of certain shapes approach a stationary orientation
Chandra Shekhar, Harish Mirajkar, Piotr Zdybel +2
This work investigates experimentally and numerically the dynamics of rigid particles settling under gravity in a highly viscous fluid. We demonstrate that certain shapes: cones, c…
Scaling law for a buckled elastic filament in a shear flow
Pawel Sznajder, Piotr Zdybel, Lujia Liu +1
We analyze the three-dimensional buckling of an elastic filament in a shear flow of a viscous fluid at low Reynolds number and high Peclet number. We apply the Euler-Bernoulli beam…
Quantum Lifshitz points and fluctuation-induced first-order phase transitions in imbalanced Fermi mixtures
Piotr Zdybel, Pawel Jakubczyk
We perform a detailed analysis of the phase transition between the uniform superfluid and normal phases in spin- and mass-imbalanced Fermi mixtures. At mean-field level we demonstr…
