The correlated electron model on a geometrically frustrated one-dimensional lattice with the spin-orbit coupling is studied. The exact solution is obtained using the Bethe ansatz. Zig-zag interaction can produce incommensurate ...

Boundary conditions for the two-dimensional fermions in ribbons of the hexagonal lattice are studied in the dice model whose energy spectrum in infinite system consists of three bands with one completely flat band of zero ...

We investigate quantum interference effects in a superconducting Cooper-pair box by taking into account the possibility of tunneling processes involving one and two Cooper pairs. The quantum dynamics is analyzed in ...

We theoretically study the effect of the spatial dispersion on the optical response of a layered hightemperature superconductor slab. The nonlocality of the inherently-anisotropic layered superconductor comes from the ...

On the basis of the continuum model for long-wavelength charge carriers, originating in the tight-binding approximation for the nearest-neighbour interaction of atoms in the crystalline lattice, we consider quantum ground-state ...

Structure and coordinate dependence of the reflected wave, as well as boundary conditions for quasi-particles of graphene and the two dimensional electron gas in sheets with abrupt lattice edges are obtained and analyzed by ...

Linear thermal expansion coefficient (LTEC) of single crystal κ-(D₄-BEDT-TTF)₂Cu[N(CN)₂]Br was studied across the crystal layers in the temperature range 2–290 K using the method of precise capacitive dilatometry. Below ...

Изучено влияние электрон-фононного взаимодействия на спектр и транспортные характеристики дираковских электронов в металлических однослойных углеродных нанотрубках. Показано, что псевдомагнитная часть потенциала взаимодействия ...

Рассчитан электронный спектр анизотропного вейлевского полуметалла (ВП) в скрещенных магнитном и электрическом полях. Показано, что электрическое поле приводит к кардинальной перестройке зон Ландау. При некотором значении ...

В монокристаллах ферробората HoFe₃(BO₃)₄ измерены основные компоненты тензора модулей упругости и пьезомодуль. Изучены спин-зависимые вклады в скорость звука, диэлектрическую проницаемость и пьезоотклик в антиферромагнитном ...
