Multipolar spin liquid in an exactly solvable model for moments
Vanuildo S. de Carvalho, Hermann Freire, Rodrigo G. Pereira
We study an exactly solvable model with bond-directional quadrupolar and octupolar interactions between spin-orbital entangled moments on the honey…
Strange metallicity in an antiferromagnetic quantum critical model: A sign-problem-free quantum Monte-Carlo study
Rafael M. P. Teixeira, Catherine Pépin, Hermann Freire
We compute transport and thermodynamic properties of a two-band spin-fermion model describing itinerant fermions in two dimensions interacting via antiferromagnetic quantum c…
Incoherent transport in a model for the strange metal phase: Memory-matrix formalism
Emile Pangburn, Anurag Banerjee, Hermann Freire +1
We revisit a phenomenological model of fermions coupled to fluctuating bosons that emerges from finite-momentum particle-particle pairs for describing the strange metal phase in th…
Charge order and emergent symmetries in cuprate superconductors
C. Pépin, H. Freire
In this paper, we present our studies of the phase diagram of the cuprate superconductors performed in recent years. We describe how a few field-theoretical concepts can be used to…
Superconductivity near a nematoelastic quantum critical point
Vanuildo S. de Carvalho, Hermann Freire
We study the pairing instability of a two-dimensional metallic system induced by Ising-nematic quantum fluctuations in the presence of an unavoidable relevant coupling of the nemat…
Raman response and shear viscosity in the non-Fermi liquid phase of Luttinger semimetals
Ipsita Mandal, Hermann Freire
Luttinger semimetals represent materials with strong spin-orbit coupling, harbouring doubly-degenerate quadratic band touchings at the Brillouin zone center. In the presence of Cou…
