Screening properties and phase transitions in unconventional plasmas for Ising-type quantum Hall states
Egil Herland, Egor Babaev, Parsa Bonderson +3
Utilizing large-scale Monte-Carlo simulations, we investigate an unconventional two-component classical plasma in two dimensions which controls the behavior of the norms and overla…
Type-1.5 superconductivity in multiband systems: magnetic response, broken symmetries and microscopic theory. A brief overview
E. Babaev, J. Carlstrom, J. Garaud +2
A conventional superconductor is described by a single complex order parameter field which has two fundamental length scales, the magnetic field penetration depth λand the coherenc…
Microscopic derivation of two-component Ginzburg-Landau model and conditions of its applicability in two-band systems
Mihail Silaev, Egor Babaev
We report a microscopic derivation of two-component Ginzburg-Landau (GL) field theory and the conditions of its validity in two-band superconductors. We also investigate the condit…
Length scales, collective modes, and type-1.5 regimes in three-band superconductors
Johan Carlstrom, Julien Garaud, Egor Babaev
The recent discovery of iron pnictide superconductors has resulted in a rapidly growing interest in multiband models with more than two bands. In this work we specifically focus on…
Topological solitons in three-band superconductors with broken time reversal symmetry
Julien Garaud, Johan Carlstrom, Egor Babaev
We show that three-band superconductors with broken time reversal symmetry allow magnetic flux-carrying stable topological solitons which have only a slightly higher energy than or…
Comment on Phys. Rev. B 83, 054515 (2011) by V. G. Kogan and J. Schmalian and comment on their reply Phys. Rev. B 86, 016502 (2012)
Egor Babaev, Mihail Silaev
The recent paper by V. G. Kogan and J. Schmalian Phys. Rev. B 83, 054515 (2011) argues that the widely used two-component Ginzburg-Landau (GL) models are not correct, and further c…
