Self-localization of magnons and magnetoroton in a binary Bose-Einstein condensate
S. V. Andreev, O. I. Utesov
We consider a two-component Bose-condensed mixture characterized by positive s-wave scattering lengths. We assume equal densities and intra-species interactions. By doing the Bogol…
Nanowire quantum dots tuned to atomic resonances
Lorenzo Leandro, Christine P. Gunnarsson, Rodion Reznik +7
Quantum dots tuned to atomic resonances represent an emerging field of hybrid quantum systems where the advantages of quantum dots and natural atoms can be combined. Embedding quan…
Anapoles in Free-Standing III-V Nanodisks Enhancing Second-Harmonic Generation
Maria Timofeeva, Lukas Lang, Flavia Timpu +5
Nonradiating electromagnetic configurations in nanostructures open new horizons for applications due to two essential features: lack of energy losses and invisibility to the propag…
Spiral plane flops in frustrated helimagnets in external magnetic field
O. I. Utesov, A. V. Syromyatnikov
We discuss theoretically frustrated Heisenberg spiral magnets in magnetic field . We demonstrate that small anisotropic spin interactions (single-ion biaxial anisotropy or d…
Analog Kerr Black hole and Penrose effect in a Bose-Einstein Condensate
D. D. Solnyshkov, C. Leblanc, S. V. Koniakhin +2
Analog physics allows simulating inaccessible objects, such as black holes, in the lab. We propose to implement an acoustic Kerr black hole with quantized angular momentum in a pol…
Force of light on a two-level atom near an ultrathin optical fiber
Fam Le Kien, D F Kornovan, S Sahar S Hejazi +4
We study the force of light on a two-level atom near an ultrathin optical fiber using the mode function method and the Green tensor technique. We show that the total force consists…
Control of multiferroic order by magnetic field in frustrated helimagnet MnI. Theory
O. I. Utesov, A. V. Syromyatnikov
We provide a theoretical description of frustrated multiferroic with a spiral magnetic ordering in magnetic field . We demonstrate that subtle interplay of excha…
Raman spectra of nanoparticles: elasticity theory-like approach for optical phonons
O. I. Utesov, A. G. Yashenkin, S. V. Koniakhin
A simple way to investigate theoretically the Raman spectra (RS) of nonpolar nanoparticles is proposed. For this aim we substitute the original lattice optical phonon eigenproblem…
Novel approach to Raman spectra of nanoparticles
S. V. Koniakhin, O. I. Utesov, I. N. Terterov +3
In crystalline nanoparticles the Raman peak is downshifted with respect to the bulk material and has asymmetric broadening. These effects are straightly related to the finite size…
Different regimes of Purcell Effect in Disordered Photonic Crystals
K. M. Morozov, A. R. Gubaydullin, K. A. Ivanov +2
We demonstrate that disorder in photonic crystals could lead to pronounced modification of spontaneous emission rate in the frequency region corresponding to the photonic band gap…
