Time-Dependent Numerical Renormalization Group Method for Multiple Quenches: Application to General Pulses and Periodic Driving
H. T. M. Nghiem, T. A. Costi
The time-dependent numerical renormalization group method (TDNRG) [Anders et al., Phys. Rev. Lett. {\bf 95}, 196801 (2005)] was recently generalized to multiple quenches and arbitr…
Generalization of the Time-Dependent Numerical Renormalization Group Method to Finite Temperatures and General Pulses
H. Nghiem, T. A. Costi
The time-dependent numerical renormalization group (td-NRG) [Anders et al. Phys. Rev. Lett. {\bf 95}, 196801 (2006)] offers the prospect of investigating in a non-perturbative mann…
Mott transition and transport crossovers in the organic compound
P. Limelette, P. Wzietek, S. Florens +6
We have performed in-plane transport measurements on the two-dimensional organic salt -(BEDT-TTF)Cu[N(CN)]Cl. A variable (gas) pressure technique allows for a detail…
Kondo effect in a magnetic field and the magnetoresistivity of Kondo alloys
T. A. Costi
The effect of a magnetic field on the spectral density of a Kondo impurity is investigated at zero and finite temperatures by using Wilson's numerical renormalization…
Renormalization Group Approach to Non-equilibrium Green Functions in Correlated Impurity Systems
T. A. Costi
We present a technique for calculating non-equilibrium Green functions for impurity systems with local interactions. We use an analogy to the calculation of response functions in t…
