Hydrodynamic theory of wetting by active particles
The accumulation of self-propelled particles on repulsive barriers is a widely observed feature in active matter. Despite being implicated in a broad range of biological processes, from biofilm formation to cytoskeletal movement, wetting of surfaces by active particles remains poorly understood. In this work, we study this active wetting by considering a model comprising an active lattice gas, interacting with a permeable barrier under periodic boundary conditions, for which an exact hydrodynam…

Flocking as a second-order phase transition in self-aligning active crystals
We study a two-dimensional crystal composed of active units governed by self-alignment. This mechanism induces a torque that aligns a particle's orientation with its velocity and leads to a phase transition from a disordered to a flocking crystal. Here, we provide the first microscopic theory that analytically maps the crystal dynamics onto a Landau-Ginzburg model, in which the velocity-dependent effective free energy undergoes a transition from a single-well shape to a Mexican-hat profile. As …

I decided that kernel module to flash an LED on disk activity had no business being a kernel module now since it's not pulling privileged data from inside the kernel to do its thing. It's a userspace binary that does the exact same thing (polling /proc/diskstats) now. It should work on any machine that has an LED controllable via /sys/class/led/ (e.g. power, caps lock, whatever)

I think it’s pretty notable that Greta Thunberg has openly blamed capitalism for the climate crisis we’re in.
She argues that the current system, driven by fossil fuel interests, colonialism, imperialism, and exploitation, is fundamentally responsible for environmental destruction and social injustice.
While she has been a prominent figure for several years, her media presence has fluctuated. Recently, she has received renewed attention, particularly after high-profile events lik…

Density-Independent Glassy Behavior in the High-Density Phase of Motility-Induced Phase Separation
We investigate the nonequilibrium dynamics of active matter using a two-dimensional active Brownian particles model. In these systems, self-propelled particles undergo motility-induced phase separation (MIPS), spontaneously segregating into dense and dilute phases. We find that in the high-density phase, local particle mobility exhibits glassy behavior, with diffusivity remaining unchanged despite variations in the global system density. As global density increases further, the system undergoes…
