A DNA segregation module for synthetic cells

MP Tran, R Chatterjee, Y Dreher, J Fichtler, K Jahnke… - Small, 2023 - Wiley Online Library
The bottom‐up construction of an artificial cell requires the realization of synthetic cell
division. Significant progress has been made toward reliable compartment division, yet …

Multiple types of aging in active glasses

R Mandal, P Sollich - Physical Review Letters, 2020 - APS
Recent experiments and simulations have revealed glassy features in, eg, cytoplasm, living
tissues and dense assemblies of self-propelled colloids. This leads to a fundamental …

Amphiphiles formed from synthetic DNA-nanomotifs mimic the stepwise dispersal of transcriptional clusters in the cell nucleus

X Tschurikow, A Gadzekpo, MP Tran, R Chatterjee… - Nano Letters, 2023 - ACS Publications
Stem cells exhibit prominent clusters controlling the transcription of genes into RNA. These
clusters form by a phase-separation mechanism, and their size and shape are controlled via …

Interplay between jamming and motility-induced phase separation in persistent self-propelling particles

J Yang, R Ni, MP Ciamarra - Physical Review E, 2022 - APS
In living and engineered systems of active particles, self-propulsion induces an unjamming
transition from a solid to a fluid phase and phase separation between a gas and a liquidlike …

Emergent clustering due to quorum sensing interactions in active matter

S Thapa, BE Pinchasik, Y Shokef - New Journal of Physics, 2024 - iopscience.iop.org
Many organisms in nature use local interactions to generate global cooperative phenomena.
To unravel how the behavior of individuals generates effective interactions within a group …

Effect of initial conditions on current fluctuations in non-interacting active particles

S Jose, A Rosso, K Ramola - Journal of Physics A: Mathematical …, 2023 - iopscience.iop.org
We investigate the effect of initial conditions on the fluctuations of the integrated density
current across the origin (x= 0) up to a given time t in a one-dimensional system of non …

Enhanced short time peak in four-point dynamic susceptibility in dense active glass-forming liquids

S Dey, A Mutneja, S Karmakar - Soft Matter, 2022 - pubs.rsc.org
Active glassy systems are simple model systems that imitate complex biological processes.
Sometimes, it becomes crucial to estimate the amount of activity present in such biological …

Configurational temperature in active matter. II. Quantifying the deviation from thermal equilibrium

S Saw, L Costigliola, JC Dyre - Physical Review E, 2023 - APS
This paper proposes using the configurational temperature T conf for quantifying how far an
active-matter system is from thermal equilibrium. We measure this “distance” by the ratio of …

Active-parameter polydispersity in the 2d ABP Yukawa model

S Saw, L Costigliola, JC Dyre - Journal of Physics: Condensed …, 2024 - iopscience.iop.org
In experiments and simulations of passive as well as active matter the most commonly
studied kind of parameter polydispersity is that of varying particles size. This paper …

Jamming and flocking in the restricted active Potts model

M Karmakar, S Chatterjee, M Mangeat, H Rieger… - Physical Review E, 2023 - APS
We study the active Potts model with either site occupancy restriction or on-site repulsion to
explore jamming and kinetic arrest in a flocking model. The incorporation of such volume …
