Slave-boson Formalism for Superconducting Pairing at Strong Coupling
Sarbajit Mazumdar, Jonas Issing, Jannis Seufert +4
We study the emergence of superconductivity in the one-band Hubbard model using the spin-rotation-invariant Kotliar-Ruckenstein slave-boson (SB) approach. Motivated by its intrinsi…
Fluctuation corrections to the free energy of strongly correlated electron systems
David Riegler, Jannis Seufert, Ronny Thomale +1
We determine the free energy of strongly correlated electron systems in the example of the Hubbard model by calculating the contribution of spin and charge fluctuations to the Gutz…
Superconductivity at an antiferromagnetic quantum critical point: the role of energy fluctuations
Jian Kang, Rafael M. Fernandes, Elihu Abrahams +1
Motivated by recent experiments reporting superconductivity only at very low temperature in a class of heavy fermion compounds, we study the impact of energy fluctuations with smal…
Superconductivity at low density near a ferroelectric quantum critical point: doped SrTiO
Peter Wölfle, Alexander V. Balatsky
Recent experiments on electron- or hole-doped SrTiO have revealed a hitherto unknown form of superconductivity, where the Fermi energy of the paired electrons is much lower t…
Conductance scaling of junctions of Luttinger-liquid wires out of equilibrium
D. N. Aristov, P. Wölfle
We develop the renormalization group theory of the conductances of N-lead junctions of spinless Luttinger-liquid wires as functions of bias voltages applied to N independent Fermi-…
Critical quasiparticles in single-impurity and lattice Kondo models
Matthias Vojta, Ralf Bulla, Peter Wölfle
Quantum criticality in systems of local moments interacting with itinerant electrons has become an important and diverse field of research. Here we review recent results which conc…
