Recent experimental studies of electron dephasing in metal and semiconductor mesoscopic structures

JJ Lin, JP Bird - Journal of Physics: Condensed Matter, 2002 - iopscience.iop.org
In this review, we discuss the results of recent experimental studies of the low-temperature
electron dephasing time (τ ϕ) in metal and semiconductor mesoscopic structures. A major …

Kondo model for the “0.7 anomaly” in transport through a quantum point contact

Y Meir, K Hirose, NS Wingreen - Physical review letters, 2002 - APS
Experiments on quantum point contacts have highlighted an anomalous conductance
plateau around 0.7 (2 e 2/h), with features suggestive of the Kondo effect. Here, an …

Mesoscopic decoherence in Aharonov-Bohm rings

AE Hansen, A Kristensen, S Pedersen, CB Sørensen… - Physical Review B, 2001 - APS
We study electron decoherence by measuring the temperature dependence of Aharonov-

A modern review of the two-level approximation

M Frasca - Annals of Physics, 2003 - Elsevier
The paradigm of the two-level atom is revisited and its perturbative analysis is discussed in
view of the principle of duality in perturbation theory. The models we consider are a two …

Percolation-type description of the metal-insulator transition in two dimensions

Y Meir - Physical review letters, 1999 - APS
A simple noninteracting-electron model, combining local quantum tunneling and global
classical percolation (due to a finite dephasing time at low temperatures), is introduced to …

Charge-fluctuation-induced dephasing in a gated mesoscopic interferometer

G Seelig, M Büttiker - Physical Review B, 2001 - APS
The reduction of the amplitude of Aharonov-Bohm oscillations in a ballistic one-channel
mesoscopic interferometer due to charge fluctuations is investigated. In the arrangement …

Low-temperature saturation of phase coherence length in topological insulators

S Islam, S Bhattacharyya, H Nhalil, M Banerjee… - Physical Review B, 2019 - APS
Implementing topological insulators as elementary units in quantum technologies requires a

Einselection in action: Decoherence and pointer states in open quantum dots

DK Ferry, R Akis, JP Bird - Physical review letters, 2004 - APS
Recent work on the role of decoherence has suggested that the decay of quantum effects is
governed by a discrete set of pointer states, which affect the quantum to classical …
