Irreversibility and symmetry breaking in the creation and annihilation of defects in active living matter
Avraham Beer, Efraim Dov Neimand, Yuv Agarwal +4
Active living matter continuously creates and annihilates topological defects in a process that remains poorly understood. Here, we investigate these dynamics in two distinct activ…

Topological spectra and entropy of chromatin loop networks
Andrea Bonato, Dom Corbett, Sergey Kitaev +3
The 3D folding of a mammalian gene can be studied by a polymer model, where the chromatin fibre is represented by a semiflexible polymer which interacts with multivalent proteins,…

Combinatorics and topological weights of chromatin loop networks
Andrea Bonato, Dom Corbett, Sergey Kitaev +3
Polymer physics models suggest that chromatin spontaneously folds into loop networks with transcription units (TUs), such as enhancers and promoters, as anchors. Here we use combin…
