Monopole magnetohydrodynamics on a plane: Magnetosonic waves and dynamo instability
Debarghya Banerjee, Roderich Moessner, Piotr Surówka
Condensed matter systems can host emergent `vacua' with particles, fields and dimension different from that of the universe we inhabit. Motivated by the appearance of emergent gaug…
Odd Cosserat elasticity in active materials
Piotr Surówka, Anton Souslov, Frank Jülicher +1
Stress-strain constitutive relations in solids with an internal angular degree of freedom can be modelled using Cosserat (also called micropolar) elasticity. In this paper, we expl…
Active ploughing through a compressible viscoelastic fluid: Unjamming and emergent nonreciprocity
Jyoti Prasad Banerjee, Rituparno Mandal, Deb Sankar Banerjee +2
A dilute suspension of active Brownian particles in a dense compressible viscoelastic fluid, forms a natural setting to study the emergence of nonreciprocity during a dynamical pha…
Hydrodynamic correlation functions of chiral active fluids
Debarghya Banerjee, Anton Souslov, Vincenzo Vitelli
The success of spectroscopy to characterise equilibrium fluids, for example the heat capacity ratio, suggests a parallel approach for active fluids. Here, we start from a hydrodyna…
Active viscoelasticity of odd materials
Debarghya Banerjee, Vincenzo Vitelli, Frank Jülicher +1
The mechanical response of active media ranging from biological gels to living tissues is governed by a subtle interplay between viscosity and elasticity. In this Letter, we genera…
Fractional hyperviscosity induced growth of bottlenecks in energy spectrum of Burgers equation solutions
Debarghya Banerjee
Energy spectrum of turbulent fluids exhibit a bump at an intermediate wavenumber, between the inertial and the dissipation range. This bump is called bottleneck. Such bottlenecks a…
