Mesoscopic fluctuations of nonlinear conductance of chaotic quantum dots
Mikhail L. Polianski, Markus Buttiker
The nonlinear dc conductance of a two-terminal chaotic cavity is investigated. The fluctuations of the conductance (anti)symmetric with respect to magnetic flux inversion through m…
Current induced transverse spin-wave instability in thin ferromagnets: beyond linear stability analysis
Shaffique Adam, Mikhail L. Polianski, Piet W. Brouwer
A sufficiently large unpolarized current can cause a spin-wave instability in thin nanomagnets with asymmetric contacts. The dynamics beyond the instability is understood in the pe…
Charge fluctuations in open chaotic cavities
M. Buttiker, M. L. Polianski
We present a discussion of the charge response and the charge fluctuations of mesoscopic chaotic cavities in terms of a generalized Wigner-Smith matrix. The Wigner-Smith matrix is…
Shot noise of photon-excited electron-hole pairs in open quantum dots
M. L. Polianski, P. Samuelsson, M. Buttiker
We investigate shot noise of photon-excited electron-hole pairs in open multi-terminal, multi-channel chaotic dots. Coulomb interactions in the dot are treated self-consistently gi…
Photon-assisted electron-hole shot noise in multi-terminal conductors
Valentin S. Rychkov, M. L. Polianski, M. Buttiker
Motivated by a recent experiment by L.-H. Reydellet et al., Phys. Rev. Lett. 90, 176803 (2003), we discuss an interpretation of photon-assisted shot noise in mesoscopic multiprobe…
