Spheroid mechanics and implications for cell invasion
Advances in Physics: X, 2021 Spheroids are widely used in vitro 3D multicellular model systems that mimic complex physiological microenvironments of tissues. As different cell types vary in deformability and adhesion, the choice of (heterogeneous) cell composition will define ...

From flocking to glassiness in dense disordered polar active matter [PDF]
Communications Physics, 2022 Active matter is a non-equilibrium system exhibiting collective behaviour and can be used to describe a wide range of biological phenomena from groups of cells to flocks of birds.

Stationary broken parity states in active matter models. [PDF]
Physical Review E, 2022 We demonstrate that several nonvariational continuum models commonly used to describe active matter as well as other active systems exhibit nongeneric behavior: each model supports asymmetric but stationary localized states even in the absence of pinning

Irreversibility, heat and information flows induced by non-reciprocal interactions
New Journal of Physics, 2020 We study the thermodynamic properties induced by non-reciprocal interactions between stochastic degrees of freedom in time- and space-continuous systems. We show that, under fairly general conditions, non-reciprocal coupling alone implies a steady energy

Critical phenomena in active matter [PDF]
Physical Review E, 2016 We investigate the effect of self-propulsion on a mean-field order-disorder transition. Starting from a $ ^4$ scalar field theory subject to an exponentially correlated noise, we exploit the Unified Colored Noise Approximation to map the non-equilibrium active dynamics onto an effective equilibrium one.

Frontiers in Physics, 2020 Upconverting nanoparticles typically absorb low frequency radiation and emit at higher frequencies relying upon multiphoton processes. One such type of particle is NaYF4:Yb,Er, which absorbs at 975 nm while emitting in visible radiation.
