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…
Stability of the Fulde-Ferrell-Larkin-Ovchinnikov states in anisotropic systems and critical behavior at thermal -axial Lifshitz points
Piotr Zdybel, Mateusz Homenda, Andrzej Chlebicki +1
We revisit the question concerning stability of nonuniform superfluid states of the Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) type to thermal and quantum fluctuations. Invoking the p…
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…
Damping of the Anderson-Bogolyubov mode by spin and mass imbalance in Fermi mixtures
Piotr Zdybel, Pawel Jakubczyk
We study the temporally nonlocal contributions to the gradient expansion of the pair fluctuation propagator for spin- and mass-imbalanced Fermi mixtures. These terms are related to…
Effective potential and quantum criticality for imbalanced Fermi mixtures
Piotr Zdybel, Pawel Jakubczyk
We study the analytical structure of the effective action for spin- and mass-imbalanced Fermi mixtures at the onset of the superfluid state. Of our particular focus is the possibil…
