Mechanism for transitions between ferromagnetic and antiferromagnetic orders in -electron metallic magnets
Marcin M. Wysokiński
We propose mechanism for pressure-induced transitions between ferromagnetic and antiferromagnetic phases that relies on a competition between characteristic energy scales ubiquitou…
Interplay of charge and spin dynamics after an interaction quench in the Hubbard model
Marcin M. Wysokinski, Michele Fabrizio
We investigate the unitary dynamics following a sudden increase of repulsion in the paramagnetic sector of the half-filled Hubbard model on a Bethe lattice, by means of a va…
Mott physics beyond Brinkman-Rice scenario
Marcin M. Wysokinski, Michele Fabrizio
The main flaw of the well-known Brinkman-Rice description, obtained through the Gutzwiller approximation, of the paramagnetic Mott transition in the Hubbard model is in neglecting…
Many-body breakdown of indirect gap in topological Kondo insulators
Marcin M. Wysokinski, Michele Fabrizio
We show that the inclusion of nonlocal correlation effects in a variational wave function for the ground state of a topological Anderson lattice Hamiltonian is capable of describin…
Gutzwiller Wave-Function Solution for Anderson Lattice Model: Emerging Universal Regimes of Heavy Quasiparticle States
Marcin Wysokinski, Jan Kaczmarczyk, Jozef Spalek
The recently proposed diagrammatic expansion (DE) technique for the full Gutzwiller wave function (GWF) is applied to the Anderson lattice model (ALM). This approach allows for a s…
