Demonstration of a fermion Quadrupling Condensate via Quantum Monte Carlo Simulation
Alexandru Golic, Egor Babaev, Johan Carlström
Fermionic condensation typically occurs via pairing. In recent decades, however, a fundamental question has emerged: whether alternative forms of order exist, such as condensates o…
Revisiting vestigial order in nematic superconductors: gauge-field mechanisms and model constraints
Ilaria Maccari, Egor Babaev, Johan Carlström
An electronic nematic order that originates from superconducting fluctuation but persists above the superconducting transition temperature is often referred to as a vestigial nemat…
Prediction of time-reversal-symmetry breaking fermionic quadrupling condensate in twisted bilayer graphene
Ilaria Maccari, Johan Carlström, Egor Babaev
Recent mean-field calculations suggest that the superconducting state of twisted bilayer graphene exhibits either a nematic order or a spontaneous breakdown of the time-reversal sy…
Chiral CP^2 skyrmions in three-band superconductors
Julien Garaud, Johan Carlstrom, Egor Babaev +1
It is shown that under certain conditions, three-component superconductors (and in particular three-band systems) allow stable topological defects different from vortices. We demon…
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…
Type-1.5 superconductivity in two-band systems
Egor Babaev, Johan Carlstrom
In the usual Ginzburg-Landau theory the critical value of the ratio of two fundamental length scales in the thery separates regimes of type-I and type-II supercond…
