Double quantum dots as detectors of high-frequency quantum noise in mesoscopic conductors
We propose a measurement setup for detecting quantum noise over a wide frequency range using inelastic transitions in a tunable two-level system as a detector. The frequency-resolving detector consists of a double quantum dot which is capacitively coupled to the leads of a nearby mesoscopic conductor. The inelastic current through the double quantum dot is calculated in response to equilibrium ...
متن کاملDouble Rashba Quantum Dots Ring as a Spin Filter
We theoretically propose a double quantum dots (QDs) ring to filter the electron spin that works due to the Rashba spin–orbit interaction (RSOI) existing inside the QDs, the spin-dependent inter-dot tunneling coupling and the magnetic flux penetrating through the ring. By varying the RSOI-induced phase factor, the magnetic flux and the strength of the spin-dependent inter-dot tunneling coupling...
متن کاملAn interferometric gravitational wave detector as a quantum-gravity apparatus
As a consequence of the extreme precision of the measurements it performs, a LIGO/VIRGO-type interferometric gravitational wave detector (IGWD) is a macroscopic apparatus for which quantum effects are not negligible. We observe that this property of IGWDs can be exploited to probe some aspects of the interface between Quantum Mechanics and Gravity. In particular, we find that IGWDs can test two...
متن کاملA Two-Dimensional Electron Gas as a Sensitive Detector for Time-Resolved Tunneling Measurements on Self-Assembled Quantum Dots
A two-dimensional electron gas (2DEG) situated nearby a single layer of self-assembled quantum dots (QDs) in an inverted high electron mobility transistor (HEMT) structure is used as a detector for time-resolved tunneling measurements. We demonstrate a strong influence of charged QDs on the conductance of the 2DEG which allows us to probe the tunneling dynamics between the 2DEG and the QDs time...
متن کاملDesign Considerations for Large Detector Arrays on Submillimeter-wave Telescopes
The emerging technology of large (∼ 10, 000 pixel) submillimeter-wave bolometer arrays presents a novel optical design problem—how can such arrays be fed by diffraction-limited telescope optics where the primary mirror is less than 100,000 wavelengths in diameter? Standard Cassegrain designs for radiotelescope optics exhibit focal surface curvature so large that detectors cannot be placed more ...
