Heat production and current noise for single- and double-cavity quantum capacitors
M. Moskalets, M. Buttiker
We analyze the frequency-dependent noise and the heat production rate for a dynamical quantum capacitor in the regime in which it emits single particles, electrons and holes. At lo…
Electron counting with a two-particle emitter
Janine Splettstoesser, Sveta Ol'khovskaya, Michael Moskalets +1
We consider two driven cavities (capacitors) connected in series via an edge state. The cavities are driven such that they emit an electron and a hole in each cycle. Depending on t…
Shot noise of a mesoscopic two-particle collider
S. Ol'khovskaya, J. Splettstoesser, M. Moskalets +1
We investigate the shot noise generated by particle emission from a mesoscopic capacitor into an edge state reflected and transmitted at a quantum point contact (QPC). For a capaci…
Dynamic scattering channels of a double barrier structure
M. Moskalets, M. Buttiker
We calculate analytically the Floquet scattering matrix for a periodically driven double-barrier structure. Our approach takes into account dynamical effects which become necessari…
Quantized dynamics of a coherent capacitor
M. Moskalets, P. Samuelsson, M. Buttiker
A quantum coherent capacitor subject to large amplitude pulse cycles can be made to emit or reabsorb an electron in each half cycle. Quantized currents with pulse cycles in the GHz…
Quantum pump driven fermionic Mach-Zehnder interferometer
S. -W. V. Chung, M. Moskalets, P. Samuelsson
We have investigated the characteristics of the currents in a pump-driven fermionic Mach-Zehnder interferometer. The system is implemented in a conductor in the quantum Hall regime…
