We analyse the conformational behaviour of a linear semiflexible homo-polymer chain confined by two geometrical constraints under a good solvent condition in two dimensions. The constraints are stair shaped impenetrable ...

We have achieved a significant experimental Rabi-splitting (3.4 meV) for confined polaritons in a planar semiconductor λ microcavity for only a single quantum well (SQW) of GaAs (10~nm) placed at the antinode. The ...

Using a simple one-dimensional Frenkel-Kontorowa type model, we have demonstrated that finite commensurate chains may undergo the commensurate-incommensurate (C-IC) transition when the chain is contaminated by isolated ...

May 15 this year was the 60th birthday of Mykola Lebovka, an outstanding Ukrainian scientist in the field of physical chemistry of condensed matter, Doctor Habilitus in Physics and Mathematics, professor, head of the ...

We revisit the particle-hole symmetry of the one-dimensional (D=1) fermionic spinless Hubbard model, associating that symmetry to the invariance of the Helmholtz free energy of the one-dimensional spin-1/2 XXZ Heisenberg ...

We study the critical behaviour of the q-state Potts model on an uncorrelated scale-free network having a power-law node degree distribution with a decay exponent λ. Previous data show that the phase diagram of the model ...

Using the group theory and the method of invariants, it is shown how the vibronic potential can be written in a matrix form and the corresponding adiabatic potentials can be found. The molecule having D₃d symmetry is ...

The analysis of the system behavior under the effect of the additive noises has been done using a simple model of shear melting. The situation with low intensity of the order parameter noise has been investigated in detail, ...
