Nonequilibrium assembly of Lennard-Jones particles on a sphere
Ivan Yu. Golushko, Olga V. Konevtsova, Daria S. Roshal +1
Studying physical mechanisms and common geometric principles underlying known spherical packings is crucial for rational design of synthetic nanocontainers. Here we model the growt…
Flat quasicrystalline tilings in terms of density wave approach
Aleksey S. Roshal, Olga V. Konevtsova, Sergei B. Rochal
Classical Landau theory considers structural phase transitions and crystallization as a condensation of several critical density waves whose wave vectors are symmetrically equivale…
Anomalous proteinaceous shells with octagonal local order
Sergei B. Rochal, Aleksey S. Roshal, Olga V. Konevtsova +1
Proteinaceous shells useful for various biomedical applications exhibit a wide range of anomalous structures that are fundamentally different from icosahedral viral capsids describ…
Topological balance of cell distributions in plane monolayers
Daria S. Roshal, Kirill K. Fedorenko, Marianne Martin +2
Most of normal proliferative epithelia of plants and metazoans are topologically invariant and characterized by similar cell distributions according to the number of cell neighbors…
Topological properties and shape of proliferative and non-proliferative cell monolayers
Daria S. Roshal, Karim Azzag, Kirill K. Fedorenko +2
During embryonic development, structures with complex geometry can emerge from planar epithelial monolayers and to study these shape transitions is of key importance for revealing…
Relaxation of interstitials in spherical colloidal crystals
D. S. Roshal, A. E. Myasnikova, S. B. Rochal
Spherical colloidal crystals (CCs) self-assemble on the interface between two liquids. These 2D structures unconventionally combine local hexagonal order and spherical geometry. No…
Slightly broken icosahedral symmetry advances Thomson problem
D. S. Roshal, A. E. Myasnikova, S. B. Rochal
To advance Thomson problem we generalize physical principles suggested by Caspar and Klug (CK) to model icosahedral capsids. Proposed simplest distortions of the CK spherical arran…
Transfer of planar orders onto a sphere: formation and properties of complex topological defects
D. S. Roshal, C. Yu. Petrov, A. E. Myasnikova +1
General topological principles how to transfer the planar orders onto a sphere are considered. Formation of extended topological defects (ETDs), which have a reconstructed inner st…
