0.4 and 0.7 conductance anomalies in quantum point contacts
A. M. Bychkov, T. M. Stace
Self-consistent modelling based on local spin-density formalism is employed to calculate conductance of quantum point contacts at finite temperatures. The total electrostatic poten…
Population inversion of driven two-level systems in a structureless bath
T. M. Stace, A. C. Doherty, S. D. Barrett
We derive a master equation for a driven double-dot damped by an unstructured phonon bath, and calculate the spectral density. We find that bath mediated photon absorption is impor…
Continuous measurement of a microwave-driven solid state qubit
S. D. Barrett, T. M. Stace
We analyze the dynamics of a continuously observed, damped, microwave driven solid state charge qubit. The qubit consists of a single electron in a double well potential, coupled t…
Two spin measurements in exchange interaction quantum computers
S. D. Barrett, T. M. Stace
We propose and analyse a method for single shot measurement of the total spin of a two electron system in a coupled quantum dot or donor impurity structure, which can be used for r…
Parity measurement of one- and two-electron double well systems
T. M. Stace, S. D. Barrett, H. -S. Goan +1
We outline a scheme to accomplish measurements of a solid state double well system (DWS) with both one and two electrons in non-localised bases. We show that, for a single particle…
Reply to Comment on "Continuous quantum measurement: inelastic tunneling and lack of current oscillations"
T. M. Stace, S. D. Barrett
We reply to a comment by Averin and Korotkov http://uk.arxiv.org/abs/cond-mat/0404549 on Stace and Barrett, PRL 92, 136802 (2004) http://link.aps.org/abstract/PRL/v92/e136802, show…
