Selective lasing in multimode periodic and non-periodic nanopillar waveguides
S. V. Zhukovsky, D. N. Chigrin, A. V. Lavrinenko +1
We investigate the lasing action in coupled multi-row nanopillar waveguides of periodic or fractal structure using the finite difference time domain (FDTD) method, coupled to the l…
Universality in Voltage-driven Nonequilibrium Phase Transitions
Johann Kroha, Michael Arnold, Beate Griepernau
We consider the non-equilibrium ferromagnetic transition of a mesoscopic sample of a resistive Stoner ferromagnet coupled to two paramagnetic leads. The transition is controlled by…
Strong vs. Weak Coupling Duality and Coupling Dependence of the Kondo Temperature in the Two-Channel Kondo Model
Christian Kolf, Johann Kroha
We perform numerical renormalization group (NRG) as well as analytical calculations for the two-channel Kondo model to obtain the dependence of the Kondo temperature on the d…
Spin Correlations and Finite-Size Effects in the One-dimensional Kondo Box
T. Hand, J. Kroha, H. Monien
We analyze the Kondo effect of a magnetic impurity attached to an ultrasmall metallic wire using the density matrix renormalization group. The spatial spin correlation function and…
Low-loss resonant modes in deterministically aperiodic nanopillar waveguides
Sergei V. Zhukovsky, Dmitry N. Chigrin, Johann Kroha
Quasiperiodic Fibonacci-like and fractal Cantor-like single- and multiple-row nanopillar waveguides are investigated theoretically employing the finite difference time domain (FDTD…
