Quantum-enabled active matter at the atomic scale
Sabrina Burgardt, Julian Feß, Alexander Guthmann +8
Active matter comprises particles that extract energy from their local environment and convert it into motion. Although active particles have been miniaturized down to the nanoscal…
Learning microstructure in active matter
Writu Dasgupta, Suvendu Mandal, Aritra K. Mukhopadhyay +1
Understanding microstructure in terms of closed-form expressions is an open challenge in nonequilibrium statistical physics. We propose a simple and generic method that combines pa…
Learning Effective Hydro-Phoretic Interactions in Active Matter
Palash Bera, Aritra K. Mukhopadhyay, Benno Liebchen
In the quest to understand large-scale collective behavior in active matter, the complexity of hydrodynamic and phoretic interactions remains a fundamental challenge. To date, most…
Automated decision-making by chemical echolocation in active droplets
Aritra K. Mukhopadhyay, Ran Niu, Linhui Fu +5
Motile microorganisms, like bacteria and algae, unify abilities like self-propulsion, autonomous navigation, and decision-making on the micron scale. While recent breakthroughs hav…
AMEP: The Active Matter Evaluation Package for Python
Lukas Hecht, Kay-Robert Dormann, Kai Luca Spanheimer +5
The Active Matter Evaluation Package (AMEP) is a Python library for analyzing simulation data of particle-based and continuum simulations. It provides a powerful and simple interfa…
Active adaptolates: motility-induced percolating structures with an adaptive packing geometry
Aritra K. Mukhopadhyay, Peter Schmelcher, Benno Liebchen
It is well known that periodic potentials can be used to induce freezing and melting in colloids. Here, we transfer this concept to active systems and find the emergence of a so-fa…
Self-solidifying active droplets showing memory-induced chirality
Kai Feng, José Carlos Ureña Marcos, Aritra K. Mukhopadhyay +4
Most synthetic microswimmers do not reach the autonomy of their biological counterparts in terms of energy supply and diversity of motion. Here we report the first all-aqueous drop…
Lattice dynamics in an emergent Zeeman lattice
M. K. H. Ome, Huaxin He, A. Mukhopadhyay +5
Periodic band structures are a hallmark phenomenon of condensed matter physics. While often imposed by external potentials, periodicity can also arise through the interplay of coup…
Interactions in Active Colloids
Benno Liebchen, Aritra K. Mukhopadhyay
The past two decades have seen a remarkable progress in the development of synthetic colloidal agents which are capable of creating directed motion in an unbiased environment at th…
Asymptotic population imbalance of an ultracold bosonic ensemble in a driven double-well
Jie Chen, Aritra K. Mukhopadhyay, Peter Schmelcher
We demonstrate that an ultracold many-body bosonic ensemble confined in an one-dimensional (1D) double well potential exhibits a population imbalance between the two wells at large…
Controlling vortical motion of particles in two-dimensional driven superlattices
Aritra K. Mukhopadhyay, Peter Schmelcher
We demonstrate the control of vortical motion of neutral classical particles in driven superlattices. Our superlattice consists of a superposition of individual lattices whose pote…
Multiple current reversals using superimposed driven lattices
Aritra K. Mukhopadhyay, Peter Schmelcher
We demonstrate that directed transport of particles in a two dimensional driven lattice can be dynamically reversed multiple times by superimposing additional spatially localized l…
Controlling transport of underdamped particles in two-dimensional driven Bravais lattices
Aritra K. Mukhopadhyay, Peter Schmelcher
We demonstrate the directed transport of underdamped particles in two dimensional lattices of arbitrary geometry driven by an unbiased ac-driving force. The direction of transport…
Dimensional coupling induced current reversal in two-dimensional driven lattices
Aritra K. Mukhopadhyay, Tianting Xie, Benno Liebchen +1
We show that the direction of directed particle transport in a two dimensional ac-driven lattice can be dynamically reversed by changing the structure of the lattice in the directi…
Simultaneous control of multi-species particle transport and segregation in driven lattices
Aritra K. Mukhopadhyay, Benno Liebchen, Peter Schmelcher
We provide a generic scheme to separate the particles of a mixture by their physical properties like mass, friction or size. The scheme employs a periodically shaken two dimensiona…
Freezing, accelerating and slowing directed currents in real time with superimposed driven lattices
Aritra K. Mukhopadhyay, Benno Liebchen, Thomas Wulf +1
We provide a generic scheme offering real time control of directed particle transport in superimposed driven lattices. This scheme allows to accelerate, slow and freeze the transpo…
Connes distance function on fuzzy sphere and the connection between geometry and statistics
Shivraj Prajapat, Yendrembam Chaoba Devi, Aritra K Mukhopadhyay +2
An algorithm to compute Connes spectral distance, adaptable to the Hilbert-Schmidt operatorial formulation of non-commutative quantum mechanics, was developed earlier by introducin…
