  2. 1. From exotic superconductivity to QCD and back again searching things in common

    Author : Egor Babaev; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Theoretical physics; Chrial symmetry; Pseudogap; vortices; knots; solitons; Teoretisk fysik; Physics; Fysik;

    Abstract : This thesis is devoted largely to two new features which Particle Physics and Condensed Matter theory have in common. The first part of the thesis is a discussion of formation of phases precursory to the chiral phase transition in relativistic models with four-fermion interactions, considered as toy models for QCD.

  4. 2. Topological excitations in field theory models of superconductivity and magnetism

    Author : Philipp Rybakov; Egor Babaev; Maxim Mostovoy; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysik; Physics; Teoretisk fysik; Theoretical Physics;

    Abstract : Topological excitations are subjects of intensive studies in physics and mathematics. In solid-state and soft matter physics, topological excitations can largely determine the thermodynamic and electromagnetic properties of materials, while in high energy physics they were theorized as particles.

  5. 3. Numerical solutions to non-linear inhomogeneous problems in Superconductivity : From sphalerons to multi-band boundary states and spontaneous magnetic fields

    Author : Andrea Ludovico Benfenati; Egor Babaev; Sedrakyan Tigran; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Teoretisk fysik; Theoretical Physics;

    Abstract : This thesis is a compilation of theoretical works focused on simulating and studying open questions regarding single and multiband superconductivity. In the last decades, with the discovery of multiband superconductors, the spectrum of potential applications has greatly widened.

  6. 4. Strong Correlation Effects in Bosonic and Fermionic Systems Through an Unbiased Quantum Monte Carlo Approach

    Author : Emil Blomquist; Egor Babaev; Johan Carlström; Barbara Capogrosso Sansone; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysik; Physics; Teoretisk fysik; Theoretical Physics;

    Abstract : Strongly interacting many-body quantum systems constitute some of the most challenging problems in physics, and exact analytical solutions are rare. In this thesis, we will investigate the models of two such systems numerically using the unbiased worm-algorithm Monte Carlo method. READ MORE

  7. 5. Multicomponent superconductivity : Vortex matter and phase transitions

    Author : Johan Carlström; Egor Babaev; Leo Radzihovsky; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Superconductivity; Ginzburg Landau; field theory; Iron pnictide;

    Abstract : The topic of this thesis is vortex-physics in multi component Ginzburg- Landau models. These models describe a newly discovered class of super- conductors with multiple superconducting gaps, and possess many properties that set them apart from single component models. READ MORE
