Glass transition in colloidal monolayers controlled by light-induced caging
Abolfazl Ahmadirahmat, Michele Caraglio, Vincent Krakoviack +1
We theoretically investigate the glass-transition problem for a quasi-two-dimensional colloidal dense suspension modulated by a one-dimensional periodic external potential as impos…
Mode-coupling theory of the glass transition for a liquid in a periodic potential
Abolfazl Ahmadirahmat, Michele Caraglio, Vincent Krakoviack +1
We derive a microscopic theory for the structural dynamics in the vicinity of the glass transition for a liquid exposed to a one-dimensional periodic potential. The periodic potent…
Transition-path sampling for Run-and-Tumble particles
Thomas Kiechl, Thomas Franosch, Michele Caraglio
We elaborate and validate a generalization of the renowned transition-path-sampling algorithm for a paradigmatic model of active particles, namely the Run-and-Tumble particles. Not…
Learning how to find targets in the micro-world: The case of intermittent active Brownian particles
Michele Caraglio, Harpreet Kaur, Lukas J. Fiderer +4
Finding the best strategy to minimize the time needed to find a given target is a crucial task both in nature and in reaching decisive technological advances. By considering learni…
Adaptive active Brownian particles searching for targets of unknown positions
Harpreet Kaur, Thomas Franosch, Michele Caraglio
Developing behavioral policies designed to efficiently solve target-search problems is a crucial issue both in nature and in the nanotechnology of the 21st century. Here, we charac…
Analytic Solution of an Active Brownian Particle in a Harmonic Well
Michele Caraglio, Thomas Franosch
We provide an analytical solution for the time-dependent Fokker-Planck equation for a two-dimensional active Brownian particle trapped in an isotropic harmonic potential. Using the…
Geometric Predictors of Knotted and Linked Arcs
Joseph L Sleiman, Robin H Burton, Michele Caraglio +2
Inspired by how certain proteins "sense" knots and entanglements in DNA molecules, here we ask if there exist local geometric features that may be used as a read-out of the underly…
Tagged-particle motion in quasi-confined colloidal hard-sphere liquids
Lukas Schrack, Charlotte F. Petersen, Michele Caraglio +2
We investigate the tagged-particle motion in a strongly interacting quasi-confined liquid using periodic boundary conditions along the confining direction. Within a mode-coupling t…
Optimal navigation strategy of active Brownian particles in target-search problems
Luigi Zanovello, Pietro Faccioli, Thomas Franosch +1
We investigate exploration patterns of a microswimmer, modeled as an active Brownian particle, searching for a target region located in a well of an energy landscape and separated…
An improved integration scheme for Mode-coupling-theory equations
Michele Caraglio, Lukas Schrack, Gerhard Jung +1
Within the mode-coupling theory (MCT) of the glass transition, we reconsider the numerical schemes to evaluate the MCT functional. Here we propose nonuniform discretizations of the…
Target search of active agents crossing high energy barriers
Luigi Zanovello, Michele Caraglio, Thomas Franosch +1
Target search by active agents in rugged energy landscapes has remained a challenge because standard enhanced sampling methods do not apply to irreversible dynamics. We overcome th…
Dynamical properties of densely packed confined hard-sphere fluids
Gerhard Jung, Michele Caraglio, Lukas Schrack +1
Numerical solutions of the mode-coupling theory (MCT) equations for a hard-sphere fluid confined between two parallel hard walls are elaborated. The governing equations feature mul…
Dynamic properties of quasi-confined colloidal hard-sphere liquids near the glass transition
Lukas Schrack, Charlotte F. Petersen, Gerhard Jung +2
The complex behavior of confined fluids arising due to a competition between layering and local packing can be disentangled by considering quasi-confined liquids, where periodic bo…
Plectoneme dynamics and statistics in braided polymers
Giada Forte, Michele Caraglio, Davide Marenduzzo +1
Braids composed of two interwoven polymer chains exhibit a buckling transition whose origin has been explained through the onset of plectonemic structures. Here we study, by a comb…
Overtwisting induces polygonal shapes in bent DNA
Michele Caraglio, Enrico Skoruppa, Enrico Carlon
By combining analytical results and simulations of various coarse-grained models we investigate the minimal energy shape of DNA minicircles which are torsionally constrained by an…
