Disorder effects in the quantum Heisenberg model: An Extended Dynamical mean-field theory analysis
S. Burdin, D. R. Grempel, M. Grilli
We investigate a quantum Heisenberg model with both antiferromagnetic and disordered nearest-neighbor couplings. We use an extended dynamical mean-field approach, which reduces the…
Electron-Phonon Correlation Effects in Molecular Transistors
C. A. Balseiro, P. S. Cornaglia, D. R. Grempel
The interplay of electron-electron and electron-phonon interactions is studied analytically in the Kondo regime. A Holstein electron-phonon coupling is shown to produce a weakening…
Universal Distribution of Kondo Temperatures in Dirty Metals
P. S. Cornaglia, D. R. Grempel, C. A. Balseiro
Kondo screening of diluted magnetic impurities in a disordered host is studied analytically and numerically in one, two and three dimensions. It is shown that in the T_K \to 0 limi…
Magnetic Quantum Phase Transitions in Kondo Lattices
Qimiao Si, Jian-Xin Zhu, D. R. Grempel
The identification of magnetic quantum critical points in heavy fermion metals has provided an ideal setting for experimentally studying quantum criticality. Motivated by these exp…
Magnetoconductance through a vibrating molecule in the Kondo regime
P. S. Cornaglia, D. R. Grempel
The effect of a magnetic field on the equilibrium spectral and transport properties of a single-molecule junction is studied using the numerical renormalization group method. The m…
Quantum transport through a deformable molecular transistor
P. S. Cornaglia, D. R. Grempel, H. Ness
The linear transport properties of a model molecular transistor with electron-electron and electron-phonon interactions were investigated analytically and numerically. The model ta…
