Gauge theory and nematic order : the rich landscape of orientational phase transition

This is life: some thoughts on self-organized structure formation in active liquids and biological systems
It has been a long-standing mystery how complex biological structures emerge from such seemingly uncoordinated building blocks as cells and tissues, in the presence of only minimal environmental guidance.

Growth-induced self-organization in bacterial colonies
Mechanical forces are known to play an important role in bacterial colonies. In this dissertation, we study the self-organization at various stages of growing bacterial colonies, and focus on the mechanical effects of cell growth.

On the geometry of fracture and frustration

Orientational Order and Confinement in Biological Tissues
This thesis investigates how cell shape and collective behavior influence the dynamics and structure of biological tissues, which are crucial for understanding processes like embryonic development, tissue regeneration, and metastasis.

Geometry and Topology in Active and Driven Systems
The key characteristic of active matter is the motion of an emergent collection (such as a flock of birds), which is driven by the consumption of energy by its active components (i.e. individual birds).

More is alive: emergent multi-scale order & collective flows in tissues
The overarching goal of this thesis is to set the foundations, but also make the first essential steps towards establishing a comprehensive, mesoscopic, hydrodynamic theory of epithelial tissues. The stage is set by an exhaustive study of topological defects in passive p-atic liquid crystals, singularities…

Topology and Geometry in Chiral Liquids
We study the interplay of topology and geometry with chirality for several passive and active systems, employing both analytical and numerical methods.

Van vormend embryo tot kankeruitzaaiing: het belang van collectieve celbeweging
Luca Giomi heeft de eerste resultaten van zijn ERC-consolidatorbeurs. Hij ontdekte dat epitheelcellen collectief bewegen, maar op verschillende manieren, afhankelijk van de schaal waarnaar je kijkt. Het is hexatisch op kleine schalen en wordt nematisch op grotere schalen: het is een multischaal orde.…

Anders gedrag actieve materie op gekromd oppervlak
Nematische vloeibare kristallen vormen de hoofdbestanddelen van de meeste televisies. De actieve variant van deze complexe vloeistoffen vormt een handig model voor natuurkundigen om de reactie te onderzoeken van actieve materie—zoals bacteriën of verkeersstromen—op mechanische en meetkundige signalen.…
