Experimental realization of the ground state for the antiferromagnetic Ising model on a triangular lattice
Ke Wang, Xing-Jian Liu, Li-Ming Tu +3
The antiferromagnetic Ising model on a triangular lattice (AFIT) exemplifies the most classical frustration system, arising from its triangular geometry that prevents all interacti…
Unstable and stable regimes of polariton condensation
F. Baboux, D. De Bernardis, V. Goblot +10
Modulational instabilities play a key role in a wide range of nonlinear optical phenomena, leading e.g. to the formation of spatial and temporal solitons, rogue waves and chaotic d…
Two-phonon assisted exciton spin relaxation due to exchange interaction in spherical quantum dots
P. Nahálková, D. Sprinzl, P. Malý +3
Spin relaxation in undoped quasi-spherical CdS quantum dots at zero magnetic fields is investigated using time- and polarization-resolved transient absorption measurements. Unlike…
Influence of the Characteristics of the STM-tip on the Electroluminescence Spectra
M. D. Croitoru, V. N. Gladilin, V. M. Fomin +4
We analyze the influence of the characteristics of the STM-tip (applied voltage, tip radius) on the electroluminescence spectra from an STM-tip-induced quantum dot taking into acco…
Optical properties of polaronic excitons in stacked quantum dots
V. N. Gladilin, S. N. Klimin, V. M. Fomin +1
We present a theoretical investigation of the optical properties of polaronic excitons in stacked self-assembled quantum dots, which is based on the non-adiabatic approach. A paral…
Quantum Transport in a Nanosize Silicon-on-Insulator Metal-Oxide-Semiconductor
M. D. Croitoru, V. N. Gladilin, V. M. Fomin +4
An approach is developed for the determination of the current flowing through a nanosize silicon-on-insulator (SOI) metal-oxide-semiconductor field-effect transistors (MOSFET). The…
Optical spectra of quantum dots: effects of non-adiabaticity
J. T. Devreese, V. M. Fomin, E. P. Pokatilov +2
It is shown that in many cases an adequate description of optical spectra of semiconductor quantum dots requires a treatment beyond the commonly used adiabatic approximation. We ha…
Photoluminescence Spectra of Quantum Dots: Enhanced Efficiency of the Electron-Phonon Interaction
J. T. Devreese, V. M. Fomin, V. N. Gladilin +1
A theory of photoluminescence in semiconductor quantum dots is developed which relies on two key ingredients. First, it takes into account non-adiabaticity of the exciton-phonon sy…
Surface-induced magnetic anisotropy for impurity spins in granular AuFe films
V. N. Gladilin, V. M. Fomin, J. T. Devreese
The theory of the surface-induced anisotropy is extended to the case of granular films of dilute magnetic alloys. Since the surface-induced blocking of a magnetic-impurity spin app…
Shape-induced magnetic anisotropy in dilute magnetic alloys
V. N. Gladilin, V. M. Fomin, J. T. Devreese
We extend the theory of the surface-induced magnetic anisotropy to mesoscopic samples with arbitrary geometry. The shape-induced anisotropy of impurity spins in small brick-shaped…
Quantum transport in the cylindrical nanosize silicon-based MOSFET
S. N. Balaban, E. P. Pokatilov, V. M. Fomin +6
A model is developed for a detailed investigation of the current flowing through a cylindrical nanosize MOSFET with a close gate electrode. The quantum mechanical features of the l…
Impurity spin magnetization of thin Fe doped Au films
E. Seynaeve, K. Temst, F. G. Aliev +4
In order to probe the influence of the surface-induced anisotropy on the impurity spin magnetization, we measure the anomalous Hall effect in thin AuFe films at magnetic fields up…
