Towards weakening of the Coulomb blockade in artificially prepared clusters of superconducting grains

Autor: Sergei Sergeenkov

Publikováno v: AIP Advances, Vol 1, Iss 2, Pp 022122-022122-3 (2011)

The relative role of dipole-dipole interactions between induced polarization moments in the total charge balance of a model system of two clusters (each cluster contains N superconducting grains) is analyzed. It is found that, due to its orientationa

Analogue of the quantum Hall effect for neutral particles with magnetic dipole moment

Autor: Sergei Sergeenkov, L. R. Ribeiro, Claudio Furtado, E. Passos

Publikováno v: Physics Letters A. 381:849-851

In this paper we investigate a possibility for the existence of an analog of the Quantum Hall Effect for neutral particles with a permanent magnetic moment $\mu$ in the presence of crossed inhomogeneous magnetic and electric fields. We predict the ap

Quantum ring in gapped graphene layer with wedge disclination in the presence of a uniform magnetic field

Autor: Sergei Sergeenkov, J. R. de S. Oliveira, Claudio Furtado, Jose Amaro Neto

Publikováno v: The European Physical Journal Plus. 133

In this paper we investigate the relativistic quantum dynamics of a massive excitation in a graphene layer with a wedge disclination in the presence of an uniform magnetic field. We use a Dirac oscillator type coupling to introduce the confining pote

On the electronic viscosity of a Dirac fluid in deformed graphene

Autor: Marcel Ausloos, Sergei Sergeenkov

We discuss the properties of the electronic viscosity of a Dirac fluid in deformed graphene by introducing a strain and velocity gradient as equivalent to a pseudo-magnetic and pseudo-electric field respectively into the Dirac equation. It is thereby

Evidence for field induced proximity type behavior in ferromagnetic nanofluid

Autor: Sergei Sergeenkov, N. S. Perov, Cristina Stan, Claudio Furtado, Maria Balasoiu, C. P. Cristescu

We report some unusual magnetic properties observed in CoFe2O4 based ferrofluid (with an average particle size of D = 6 nm). More precisely, in addition to the low-field ferromagnetic (FM) phase transition with an intrinsic Curie temperature T_Cb=350

Gap-dependent mass of a photon in a photonic topological insulator

Autor: Sergei Sergeenkov, Marcelo da Silva Vieira, Claudio Furtado

Publikováno v: Physical Review A. 96

By using an analogy with axionic like systems, we study light propagation in periodic photonic topological insulator (PTI). The main result of this paper is an explicit expression for the PTI band structure. More specifically, it was found that for n

2D arrays of Josephson nanocontacts and nanogranular superconductors

Autor: Sergei Sergeenkov

By introducing a realistic model of nanogranular superconductors (NGS) based on 2D arrays of Josephson nanocontacts (created by a network of twin-boundary dislocations with strain fields acting as insulating barriers between hole-rich domains), in th

Deciphering M-T diagram of shape memory Heusler alloys: reentrance, plateau and beyond

Autor: Alexey Mashirov, Sergei Sergeenkov, Pnina Ari-Gur, Victor Koledov, Vladimir G. Shavrov, A. Y. Takeuchi, Alexander P. Kamantsev, Fernando M. Araújo-Moreira, O. F. de Lima, A. M. Gomes, C. Cordova

We present our recent results on temperature behaviour of magnetization observed in Ni_47Mn_39In_14 Heusler alloys. Three regions can be distinguished in the M-T diagram: (I) low temperature martensitic phase (with the Curie temperature T_CM = 140 K)
