We use higher-dimensional bosonization to study the normal state of electrons in weakly coupled metallic chains interacting with long-range Coulomb forces. Particular attention is paid to the crossover between Luttinger and Fermi liquid behavior as the interchain hopping is varied. Although in the physically interesting case of finite but small interchain hopping the quasi-particle residue does not vanish, the single-particle Green's function exhibits the signature of Luttinger liquid behavior…

Dimensionality of metallic atomic wires on surfaces
We investigate the low-energy collective charge excitations (plasmons, holons) in metallic atomic wires deposited on semiconducting substrates. These systems are described by two-dimensional
Exact Solution of a 2D Interacting Fermion Model
We study an exactly solvable quantum field theory (QFT) model describing interacting fermions in 2+1 dimensions. This model is motivated by physical arguments suggesting that it provides an effective
Applications of the functional renormalization group to quantum liquids
Non-perturbative effects and strong interactions still challenge the theoretical treatment of condensed matter physics. One of the most promising tools to study these effects is the renormalization
Photoemission properties of quasi-one-dimensional conductors
We calculate the one-particle spectral function and the corresponding derived quantities for a chain lattice with a one-dimensional conducting electron band, and with a three-dimensional long-range
Spectral properties of quasi-one-dimensional conductors with a finite transverse band dispersion
We determine the one-particle spectral function and the corresponding derived quantities for the conducting chain lattice with finite inter-chain hopping and three-dimensional long-range Coulomb
Equivalence of Rashba-Hubbard and Hubbard chains
We review the fact that U(1) gauge symmetry enables the mapping of one-dimensional Hubbard chains with Rashba-type spin orbit coupling to renormalized Hubbard Hamiltonians. The existence of the
Impurities and quantum interference in the chains of YBa2Cu3O6+x.
TLDR
It is shown that a resonance state in the chain density of states is induced only by a magnetic impurity, and the spatial form of the resonance reflects the particle-hole nature of chain superconductivity and therefore distinguishes it from other broken symmetry phases.
Anisotropic 2D metallicity: plasmons in Ge(1 0 0)-Au.
TLDR
It is concluded that the Ge(0’0 1)-Au system is reasonably well described by a strongly anisotropic 2D Fermi liquid, but is incompatible with a TLL.

Bosonization of Interacting Fermions in Arbitrary Dimensions
This review is a summary of my work (partially in collaboration with Kurt Schoenhammer) on higher-dimensional bosonization during the years 1994-1996. It has been published as a book entitled
Calculation of the single-particle Green's function of interacting fermions in arbitrary dimension via functional bosonization
The single-particle Green's function of an interacting Fermi system with dominant forward scattering is calculated by decoupling the interaction by means of a Hubbard-Stratonowich transformation
