Critical phenomena of emergent magnetic monopoles in a chiral magnet.

Nature communications

Kanazawa N, Nii Y, Zhang XX, Mishchenko AS, De Filippis G, Kagawa F, Iwasa Y, Nagaosa N, Tokura Y.
PMID: 27181484
Nat Commun. 2016 May 16;7:11622. doi: 10.1038/ncomms11622.

Second-order continuous phase transitions are characterized by symmetry breaking with order parameters. Topological orders of electrons, characterized by the topological index defined in momentum space, provide a distinct perspective for phase transitions, which are categorized as quantum phase transitions...

Nat Commun. 2016 Jan 27;7:10386. doi: 10.1038/ncomms10386.

Interplay of spin, charge, orbital and lattice degrees of freedom in oxide heterostructures results in a plethora of fascinating properties, which can be exploited in new generations of electronic devices with enhanced functionalities. The paradigm example is the interface...

Observation of anomalous Hall effect in a non-magnetic two-dimensional electron system.

Nature communications

Maryenko D, Mishchenko AS, Bahramy MS, Ernst A, Falson J, Kozuka Y, Tsukazaki A, Nagaosa N, Kawasaki M.
PMID: 28300133
Nat Commun. 2017 Mar 16;8:14777. doi: 10.1038/ncomms14777.

Anomalous Hall effect, a manifestation of Hall effect occurring in systems without time-reversal symmetry, has been mostly observed in ferromagnetically ordered materials. However, its realization in high-mobility two-dimensional electron system remains elusive, as the incorporation of magnetic moments deteriorates...

Crossover from super- to subdiffusive motion and memory effects in crystalline organic semiconductors.

Physical review letters

De Filippis G, Cataudella V, Mishchenko AS, Nagaosa N, Fierro A, de Candia A.
PMID: 25768773
Phys Rev Lett. 2015 Feb 27;114(8):086601. doi: 10.1103/PhysRevLett.114.086601. Epub 2015 Feb 24.

The transport properties at finite temperature of crystalline organic semiconductors are investigated, within the Su-Schrieffer-Heeger model, by combining an exact diagonalization technique, MonteĀ Carlo approaches, and a maximum entropy method. The temperature-dependent mobility data measured in single crystals of...

Objective. The study examined the gut (colonic) microbiota in children being domiciled in contaminated zones and suffering the cardiac connective tissue dysplasia syndrome (CCTDS). Materials and methods. The study included 99 children living in contaminated zones. Study subjects were...

Nonlinear voltage dependence of the shot noise in mesoscopic degenerate conductors with strong electron-electron scattering.

Physical review letters

Mishchenko EG.
PMID: 11056645
Phys Rev Lett. 2000 Nov 06;85(19):4144-7. doi: 10.1103/PhysRevLett.85.4144.

It is shown that measurements of zero-frequency shot noise can provide information on electron-electron interaction, because the strong interaction results in the nonlinear voltage dependence of the shot noise in metallic wires. This is due to the fact that...

Theory of ferromagnetism in Ca(1-x)La(x)B(6).

Physical review letters

Murakami S, Shindou R, Nagaosa N, Mishchenko AS.
PMID: 11909486
Phys Rev Lett. 2002 Mar 25;88(12):126404. doi: 10.1103/PhysRevLett.88.126404. Epub 2002 Mar 12.

Novel ferromagnetism in Ca(1-x)La(x)B(6) is studied in terms of the Ginzburg-Landau theory for excitonic-order parameters, taking into account symmetry of the wave functions. We found that the minima of the free energy break both inversion and time-reversal symmetries, while...

We use precise T-matrix calculations for prolate and oblate spheroids, Chebyshev particles, and spheres cut by a plane to study the evolution of Lorenz-Mie morphology-dependent resonances (MDRs) with increasing asphericity of nearly spherical particles in random orientation. We show...

We have examined the Maxwell-Garnett, inverted Maxwell-Garnett, and Bruggeman rules for evaluation of the mean permittivity involving partially empty cells at particle surface in conjunction with the finite-difference time-domain (FDTD) computation. Sensitivity studies show that the inverted Maxwell-Garnett rule...
