Effect of magnetic field on competition between superconductivity and charge order below the pseudogap state
H. Meier, M. Einenkel, C. Pépin +1
We theoretically investigate the T-B phase diagram of cuprates building on the SU(2) pseudogap order recently obtained from the spin-fermion model. At low temperatures, our analysi…
Low energy excitations and singular contributions in the thermodynamics of clean Fermi liquids
H. Meier, C. Pépin, K. B. Efetov
Using a recently suggested method of bosonization in an arbitrary dimension, we study the anomalous contribution of the low energy spin and charge excitations to thermodynamic quan…
Reply to the Comment by Galanakis \textit{et al} on the paper \textquotedblleft Exact bosonization for an interacting Fermi gas in arbitrary dimensions"
K. B. Efetov, C. Pépin, H. Meier
It is shown that the criticism presented in the Comment by Galanakis et al \cite{1} on the paper by Efetov et al \cite{2} is irrelevant to the bosonization approach.
Describing systems of interacting fermions by boson models: exact mapping in arbitrary dimension and applications
K. B. Efetov, C. Pépin, H. Meier
We develop a new method that allows us to map models of interacting fermions onto bosonic models describing collective excitations in an arbitrary dimension. This mapping becomes e…
Exact bosonization for an interacting Fermi gas in arbitrary dimensions
K. B. Efetov, C. Pepin, H. Meier
We present an exact mapping of models of interacting fermions onto boson models. The bosons correspond to collective excitations in the initial fermionic models. This bosonization…
