Collective search-and-capture under competing assignment policies
Néstor Sepúlveda
We study a minimal lattice model of active search-and-capture in which persistent random walkers locate and irreversibly capture immobile targets through a finite-range, mutually e…
Collective phases in overdamped magnetic self-propelled spherocylinders
Francisca Guzmán-Lastra, Néstor Sepúlveda
We study the collective dynamics of self-propelled spherocylinders carrying magnetic dipole moments in two dimensions. Magnetic interactions are modeled as two opposite monopoles $…
Active Growth Layer Induced by Micromechanical Feedback Shapes Proliferating Cell Collectives
Fidel Ãlvarez-Murphy, Ignacio Medina, Néstor Sepúlveda +1
Proliferating cell collectives often develop an active growth layer near their boundary that regulates expansion and morphology, as observed in systems ranging from bacterial biofi…
Macroscopic bioinspired magnetic active matter and the physical limits of magnetotaxis
Néstor Sepúlveda, Francisca Guzmán-Lastra, Miguel Carrasco +4
Magnetotactic bacteria (MTB) are endowed with an exquisite orientation mechanism allowing them to swim along the geomagnetic field lines. This mechanism consists of a chain of bio-…
A correspondence between the Rabi model and an Ising model with long-range interactions
Bruno Scheihing-Hitschfeld, Néstor Sepúlveda
By means of Trotter's formula, we show that transition amplitudes between a class of generalized coherent states in the Rabi model can be understood in terms of a certain Ising mod…
