Right in time for Christmas  ! We are very happy to announce that Henry’s latest work was published today in Physical Review Letters. In this paper, we study entropy production in the most generic mixture of conserved phase fields with nonreciprocal couplings and additive conservative noise. In the special case of the Non-Reciprocal Cahn Hilliard model, we observe a nontrivial scaling of the entropy production rate across a parity-time symmetry breaking phase transition for which we derive an exact expression!

Interested in the growth of biological tissues? Wonder how one can model this on the computer using a lattice Boltzmann approach? Check out Andy’s second paper published today in Phys. Rev. Research.

Another study hot off the press! In a paper published today in Phys. Rev. Research led by Luca Cocconi, we show that reciprocity-breaking fluctuations about a reciprocal mean coupling are sufficient to drive persistent motion reminiscent of self-propulsion in active bound states.

Very happy to see this neat paper published in Ecology and Evolution, fruit of a great collaboration with Dr Loïc Marrec and Claudia Bank at the Institut für Ökologie und Evolution from the Universität Bern! We show that using a deterministic equation to describe stochastic population growth may not be a good idea! 😱 In addition to explaining why 🧐, we solve the stochastic dynamics! 😇

Our latest paper on non-equilibrium phase separation in a model of scalar active matter is out today in Phys. Rev. E! Congrats to Henry who led the study. In this paper, we capture type-IV pili-mediated interactions in bacteria in a microscopic model then coarse-grain the dynamics formally, describing large scale clustering using non-equilibrium phase separation field theories (Active Model B+)!

In 2021, Thibault was selected by the editorial board of the Journal of Physics A as an one of their Emerging Talents Today, J. Phys. A publishes the paper we contributed to the Emerging Talents 2021 collection. If you are interested in reading about the nonequilibrium thermodynamics of diffusion in fluctuating potentials, you can find the full text here. In this paper, we derive general results for the average rate of entropy production of a Brownian particle in a fluctuating potential, including exact results for harmonic confining potentials. Our results give a new perspective on the thermodynamics of stochastic resetting processes and the thermodynamics of optical traps but we believe that it lays the foundations to study the non-equilibirum thermodynamics properties of fluctuating interactions in living systems!

Intrigued by phase transitions and phase separation in active polar fluids? Check out our Letter published today in Phys. Rev. Research. In this paper, we unify these diverse phase transitions and phase coexistences into a single formulation based on generic hydrodynamic equations for active fluids. In doing so, we also reveal a novel comoving coexistence phase and a multicritical point.

How can a collection of motile cells, each generating contractile nematic stresses in isolation, become an extensile nematic at the tissue level? We answer this question in our paper published today in PRL! Our results are described in the following Synopsis in Physics. We thank the editors for selecting our paper as an Editor’s Suggestion.

Following our earlier works on the plasticity of emulsions subject to depletion attraction, in our latest paper we use functionalized emulsions as a model for cellular tissues and study the dynamics and mechanical response of this biomimetic system under flow. We show that adhesion acts as a trigger of droplet polarization shedding some light on the origin of polarization processes during morphogenesis.
