RN-SDEs: Limited-Angle CT Reconstruction with Residual Null-Space Diffusion Stochastic Differential Equations
Jiaqi Guo, Santiago Lopez-Tapia, Wing Shun Li +7
Computed tomography is a widely used imaging modality with applications ranging from medical imaging to material analysis. One major challenge arises from the lack of scanning info…
Characterizing hydrogel behavior under compression with gel-freezing osmometry
Yanxia Feng, Dominic Gerber, Stefanie Heyden +4
Hydrogels are particularly versatile materials that are widely found in both Nature and industry. One key reason for this versatility is their high water content, which lets them d…
Local Volume Concentration, Packing Domains and Scaling Properties of Chromatin
Marcelo Carignano, Martin Kröger, Luay Almassalha +6
We propose the Self Returning Excluded Volume (SR-EV) model for the structure of chromatin based on stochastic rules and physical interactions. The SR-EV rules of return generate c…
Siloxane molecules: Nonlinear elastic behavior and fracture characteristics
Tianchi Li, Eric R. Dufresne, Martin Kröger +1
Fracture phenomena in soft materials span multiple length- and timescales. This poses a major challenge in computational modeling and predictive materials design. To pass quantitat…
Increase in rod diffusivity emerges even in Markovian nature
Fumiaki Nakai, Martin Kröger, Takato Ishida +3
Rod-shaped particles embedded in certain matrices have been reported to exhibit an increase in their center of mass diffusivity upon increasing the matrix density. This increase ha…
Reconfigurable Artificial Microswimmers with Internal Feedback
L. Alvarez, M. A. Fernandez-Rodriguez, A. Alegria +4
Micron-size self-propelling particles are often proposed as synthetic models for biological microswimmers, yet they lack internally regulated adaptation, which is central to the au…
Emergence of stationary uphill currents in 2D Ising models: the role of reservoirs and boundary conditions
M. Colangeli, C. Giberti, C. Vernia +1
We investigate the dynamics of a 2D Ising model on a square lattice with conservative Kawasaki dynamics in the bulk, coupled with two external reservoirs that pull the dynamics out…
Dynamics and wetting behavior of soft particles at a fluid-fluid interface
Siddarth A. Vasudevan, Astrid Rauh, Martin Kröger +2
We investigate the conformation, position, and dynamics of core-shell nanoparticles (CSNPs) composed of a silica core encapsulated in a cross-linked poly-N-isopropylacrylamide shel…
Assessing numerical methods for molecular and particle simulation
Xiaocheng Shang, Martin Kröger, Benedict Leimkuhler
We discuss the design of state-of-the-art numerical methods for molecular dynamics, focusing on the demands of soft matter simulation, where the purposes include sampling and dynam…
Boltzmann equation and hydrodynamic fluctuations
M. Colangeli, M. Kroger, H. C. Ottinger
We apply the method of invariant manifolds to derive equations of generalized hydrodynamics from the linearized Boltzmann equation and determine exact transport coefficients, obeyi…
Topological analysis of polymeric melts: Chain length effects and fast-converging estimators for entanglement length
Robert S. Hoy, Katerina Foteinopoulou, Martin Kröger
Primitive path analyses of entanglements are performed over a wide range of chain lengths for both bead spring and atomistic polyethylene polymer melts. Estimators for the entangle…
Systematic time-scale-bridging molecular dynamics applied to flowing polymer melts
Patrick Ilg, Hans Christian Öttinger, Martin Kröger
We present a novel thermodynamically guided, low-noise, time-scale bridging, and pertinently efficient strategy for the dynamic simulation of microscopic models for complex fluids.…
Canonical Distribution Functions in Polymer Dynamics: II. Liquid--Crystalline Polymers
Patrick Ilg, Iliya V. Karlin, Martin Kröger +1
The quasi--equilibrium approximation is employed as a systematic tool for solving the problem of deriving constitutive equations from kinetic models of liquid--crystalline polymers…
