Disordered loops in the two-dimensional antiferromagnetic spin-fermion model
Tilman Enss, Sergio Caprara, Claudio Castellani +2
The spin-fermion model has long been used to describe the quantum-critical behavior of 2d electron systems near an antiferromagnetic (AFM) instability. Recently, the standard proce…
Quantum phase transition in easy-axis antiferromagnetic integer-spin chains
M. Capone, S. Caprara, L. Cataldi
Antiferromagnetic Heisenberg integer-spin chains are characterized by a spin-liquid ground state with no long-range order, due to the relevance of quantum fluctuations. Spin anisot…
Phase Diagram of the 1D Kondo Lattice Model
I. P. McCulloch, M. Gulacsi, S. Caprara +1
We determine the boundary of the fully polarized ferromagnetic ground state in the one dimensional Kondo lattice model at partial conduction electron band filling by using a newly…
