Quantum entanglement, local indicators and effect of external fields in the Kugel-Khomskii model
V. E. Valiulin, A. V. Mikheyenkov, N. M. Chtchelkatchev +1
Using the exact diagonalization technique, we determine the energy spectrum and wave functions for finite chains described by the two-spin (Kugel--Khomskii) model with different ty…
Ab initio based description of the unusual temperature increase of the electric field gradient at Ti sites in rutile TiO2
A. V. Nikolaev, N. M. Chtchelkatchev, A. V. Bibikov +2
Combining a precise ab initio electron band structure calculation of the TiO2 rutile structure with the temperature evolution of the Ti mean-square displacements, we reproduce a pu…
Single germanium vacancy centres in nanodiamonds with bulk-like spectral stability
Mackrine Nahra, Daniel Alshamaa, Regis Deturche +4
Motivated by the success of group IV colour centres in nanodiamonds (NDs) for hybrid technology requiring a single photon source, we study single germanium-vacancy (GeV) centre…
A new mechanism of structural transition in 2D Hertzian spheres in the presence of random pinning
E. N. Tsiok, Yu. D. Fomin, E. A. Gaiduk +1
Using molecular dynamics simulation we have investigated the influence of random pinning on the phase diagram and melting scenarios of a two-dimensional (2D) system with the Hertz…
Structure of the simple harmonic-repulsive system in liquid and glassy states studied by the triple correlation function
V. A. Levashov, R. E. Ryltsev, N. M. Chtchelkatchev
An efficient description of the structures of liquids and, in particular, the structural changes that happen with liquids on supercooling remains to be a challenge. The systems com…
Universal lower bounds on energy and momentum diffusion in liquids
K. Trachenko, M. Baggioli, K. Behnia +1
Thermal energy can be conducted by different mechanisms including by single particles or collective excitations. Thermal conductivity is system-specific and shows a richness of beh…
