DOI: 10.1016/j.neucom.2020.04.162
Abstract: Neuromorphic networks can be described in terms of coarse-grained variables, where emergent sustained behaviours spontaneously arise if stochasticity is properly taken in account. For example it has been recently found that a directed linear chain… read more here.

DOI: 10.1038/s41598-021-94458-0
Abstract: Chemotaxis enables cells to systematically approach distant targets that emit a diffusible guiding substance. However, the visual observation of an encounter between a cell and a target does not necessarily indicate the presence of a… read more here.

DOI: 10.1088/1751-8121/ab5634
Abstract: The presence of algebraically decaying long-range interactions may alter the critical as well as topological behaviour of a quantum many-body systems. However, when the interaction decays at a faster rate, the short-range behaviour is expected… read more here.

DOI: 10.1103/physreva.99.052332
Abstract: State preparation protocols ideally require as minimal operations as possible, in order to be implemented in near-term, potentially noisy quantum devices. Motivated by long range interactions (LRIs) intrinsic to many present-day experimental platforms (trapped ions,… read more here.
