Topological instability and reentrant crystallization in active solids
Zory Davoyan, Aditya Jha, Anton Souslov
We extend the KTHNY theory of defect-mediated melting in two dimensions to the case of active solids exhibiting both non-reciprocal (odd) elasticity and Cosserat (micropolar) coupl…

Odd pathways speed up self-assembly
Dawid Dopierała, Luca Cocconi, Robert L. Jack +1
Active self-assembly can bypass equilibrium bottlenecks through external energy injection. However, generic driving typically distorts target structures and requires sustained ener…

Non-reciprocal Ising gauge theory
Nilotpal Chakraborty, Anton Souslov, Claudio Castelnovo
Non-reciprocity and geometric frustration enable many-body systems to avoid crystalline order and instead exhibit complex, liquid-like behavior. Here we show that their interplay i…
