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…
Terahertz frequency selective surfaces using heterostructures based on two-dimensional diffraction grating of single-walled carbon nanotubes
Alexander M. Lerer, Pavel E. Timoshenko, Sergei B. Rochal
For single-walled carbon nanotubes (SWCNTs) with a length of 1-50 nm, the surface plasmon-polariton (SPP) resonance is within the terahertz frequency range; therefore, SWCNT lattic…
Tight binding approximation for bilayer graphene and nanotube structures: from commensurability to incommensurability between the layers
D. V. Chalin, D. I. Levshov, A. E. Myasnikova +1
One- and two-dimensional bilayer systems are examples of ultra-tunable quantum materials that are considered as the basis for the new generation of electronic and photonic devices.…
Band structure and inter-tube optical transitions in double-walled carbon nanotubes
D. V. Chalin, S. B. Rochal
Usually, in optical spectra of double-walled carbon nanotubes (DWCNTs) weak van der Waals coupling between the layers leads only to a small shift of transition energies with respec…
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…
Vibrational heat capacity of carbon nanotubes in low and ultra-low temperature regions
M. V. Avramenko, I. Yu. Golushko, A. E. Myasnikova +1
We develop a continuous theory of low-frequency dynamics for single-walled carbon nanotubes (SWCNTs) weakly interacting with the environment. In the frame of the approach proposed…
Extended topological defects as sources and outlets of dislocations in spherical hexagonal crystals
D. S. Roshal, K. Yu. Petrov, A. E. Myasnikova +1
Extended topological defects (ETDs) arising in spherical hexagonal crystals due to their curvature are considered. These prevalent defects carry a unit total topological charge and…
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…
Symmetry of the carbon nanotube modes and their origin from the phonon branches of graphene
M. V. Avramenko, S. B. Rochal, Yu. I. Yuzyuk
A new group-theory method to relate a spectrum of carbon nanotubes with that of a graphene monolayer is elaborated. The spectrum reconstruction is performed using a virtual interme…
