📢Memory (persistent noise) triggers non-eq. phase transitions in scalar field theories - in situations where nothing happens if memoryless --> just published in @PhysRevLett #statphys #activematter thanks @matteo_paoluzzi @natxopago A. Crisanti @UB_ICS @FisicaUB.
Our work on persistent noise-driven phase separation on scalar field theory is finally out! @demian_levis @natxopago

As a theorist, it's amazing to see that statistical physics works firsthand! I truly enjoyed building an experiment from scratch with brilliant students like JPCarrillo AGarces. @CUCA_labo @FisicaUB #statphys #activematter.
First experimental results with self-propelled robots are out!! Activity vs. external drive => depinning transition + exact calculations in quantitative agreement with experiments! Fantastic PhD work JPCarrillo and @AdriaGarces @UB_ICS #activematter .

Published @PhysRevLett! How nonreciprocity affects the behaviour of topological defects? they are reshaped, their annihilation can be enhanced or hindered, +1 -1 charges move differently. PhD work of YRouzaire @FisicaUB #ubics with @natxopago DPearce.
journals.aps.org
We show how nonreciprocal ferromagnetic interactions between neighboring planar spins in two dimensions, affect the behavior of topological defects. Nonreciprocity is introduced by weighting the...

👉New preprint! we formulate generic non-reciprocal couplings between Ising spins, and how vision-cone FM interactions affect the mean-field and 2D Ising universality class. Great work of @twAdriG First preprint of newly established lab @CUCA_labo !🍾🍾.
arxiv.org
We present a general framework for incorporating non-reciprocal interactions into the Ising model with Glauber dynamics, without requiring multiple species. We then focus on a model with...
