Solubility of poorly soluble species in bulk and nanopores from grand-canonical Wang-Landau sampling
Russell Kajouri, Adyant Agrawal, Philipp Stärk +2
Poorly soluble species can have mean populations below one in small systems such as nanopores. In this regime, the grand-potential minimum, which identifies the most probable parti…
Intermittent flow paths in biofilms grown in a microfluidic channel
Kerem Bozkurt, Christoph Lohrmann, Felix Weinhardt +5
Biofilms exposed to flow experience shear stress, which leads to a competitive interaction between the growth and development of a biofilm and shearing. In this study, Pseudonomas…
Generating Minimal Training Sets for Machine Learned Potentials
Jan Finkbeiner, Samuel Tovey, Christian Holm
This letter presents a novel approach for identifying uncorrelated atomic configurations from extensive data sets with a non-standard neural network workflow known as random networ…
Environmental effects on emergent strategy in micro-scale multi-agent reinforcement learning
Samuel Tovey, David Zimmer, Christoph Lohrmann +5
Multi-Agent Reinforcement Learning (MARL) is a promising candidate for realizing efficient control of microscopic particles, of which micro-robots are a subset. However, the micros…
Towards a Phenomenological Understanding of Neural Networks: Data
Samuel Tovey, Sven Krippendorf, Konstantin Nikolaou +1
A theory of neural networks (NNs) built upon collective variables would provide scientists with the tools to better understand the learning process at every stage. In this work, we…
A Generalized Grand-Reaction Method for Modelling the Exchange of Weak (Polyprotic) Acids between a Solution and a Weak Polyelectrolyte Phase
David Beyer, Christian Holm
We introduce a Monte-Carlo method that allows for the simulation of a polymeric phase containing a weak polyelectrolyte, which is coupled to a reservoir at a fixed pH, salt concent…
Explaining Giant Apparent Shifts in Weak Polyelectrolyte Brushes
David Beyer, Peter Košovan, Christian Holm
Recent experiments on weak polyelectrolyte brushes found marked shifts in the effective p that are linear in the logarithm of the salt concentration. Comparing explic…
Optimal motility strategies for self-propelled agents to explore porous media
Christoph Lohrmann, Christian Holm
Micro-robots for, e.g., biomedical applications, need to be equipped with motility strategies that enable them to navigate through complex environments. Inspired by biological micr…
Ratcheting charged polymers through symmetric nanopores using pulsed fields: Designing a low pass filter for concentrating DNA
Le Qiao, Kai Szuttor, Christian Holm +1
We present a new concept for the separation of DNA molecules by contour length that combines a nanofluidic ratchet, nanopore translocation and pulsed fields. Using Langevin Dynamic…
Order and Information in the Patterns of Spinning Magnetic Micro-disks at the Air-water Interface
Wendong Wang, Gaurav Gardi, Paolo Malgaretti +9
The application of the Shannon entropy to study the relationship between information and structures has yielded insights into molecular and material systems. However, the difficult…
Critical Exponents of the Classical 3D Heisenberg Model: A Single-Cluster Monte Carlo Study
Christian Holm, Wolfhard Janke
We have simulated the three-dimensional Heisenberg model on simple cubic lattices, using the single-cluster Monte Carlo update algorithm. The expected pronounced reduction of criti…
