Bandstructure meets many-body theory: The LDA+DMFT method
K. Held, O. K. Andersen, M. Feldbacher +2
Ab initio calculation of the electronic properties of materials is a major challenge for solid state theory. Whereas the experience of forty years has proven density functional the…
Reply to a Comment on ``Projective Quantum Monte Carlo Method for the Anderson Impurity Model and its Application to Dynamical Mean Field Theory''
M. Feldbacher, K. Held, F. F. Assaad
In our reply, we show that the objections put forward in cond-mat/0508763 concerning our paper, Phys. Rev. Lett. 93, 136405 (2004), are not valid: (i) There is no orthogonality cat…
Pressure-induced metal-insulator transition in LaMnO3 is not of Mott-Hubbard type
A. Yamasaki, M. Feldbacher, Y. -F. Yang +2
Calculations employing the local density approximation combined with static and dynamical mean-field theories (LDA+U and LDA+DMFT) indicate that the metal-insulator transition obse…
Some clarifications on cond-mat/0508763 by M. I. Katsnelson
M. Feldbacher, R. Arita, K. Held +1
Katsnelson submitted his Comment on our paper "Projective Quantum Monte Carlo Method for the Anderson Impurity Model and its Application to Dynamical Mean Field Theory" to Phys. Re…
Projective Quantum Monte Carlo Method for the Anderson Impurity Model and its Application to Dynamical Mean Field Theory
M. Feldbacher, K. Held, F. F. Assaad
We develop a projective quantum Monte Carlo algorithm of the Hirsch-Fye type for obtaining ground state properties of the Anderson impurity model. This method is employed to solve…
Coexistence of s-wave Superconductivity and Antiferromagnetism
M. Feldbacher, F. F. Assaad, F. Hebert +1
We study the phase diagram of a new model that exhibits a first order transition between s-wave superconducting and antiferromagnetic phases. The model, a generalized Hubbard model…
