The Braess paradox, known for traffic and other classical networks, lies in the fact that adding a new route to a congested network in an attempt to relieve congestion can degrade counterintuitively the overall network performance. Recently, we have extended the concept of the Braess paradox to semiconductor mesoscopic networks, whose transport properties are governed by quantum physics. In this paper, we demonstrate theoretically that, alike in classical systems, congestion plays a key role in… Expand
On the origins of transport inefficiencies in mesoscopic networks
It is shown that either Coulomb Blockade resonances due to disorder-induced localized states or Fabry-Perot interferences tuned by the tip-induced electrostatic perturbation are at the origin of transport inefficiencies in the network, which are lifted when gradually closing one channel of the network with the tip.

The Braess Paradox
The Braess Paradox is a counterintuitive phenomenon that may arise in congested urban transportation networks that was discovered by Dietrich Braess and described in his classic 1968 paper. InExpand
Physical proof of the occurrence of the Braess Paradox in electrical circuits
It is shown that the Braess Paradox can occur in electrical circuits consisting of diodes and resistors, and this discovery identifies novel circuits in which the voltage and current can be independently adjusted. Expand
Wave packet propagation through branched quantum rings under applied magnetic fields
Abstract We investigate the effect of opening and closing pathways on the dynamics of electron wave packets in semiconductor quantum rings with different geometries. Our analysis is based on the timeExpand
Scanning Probe Electronic Imaging of Lithographically Patterned Quantum Rings
Quantum rings patterned from two-dimensional semiconductor heterostructures exhibit a wealth of quantum transport phenomena at low temperature and in a magnetic field that can be mapped in real spaceExpand
Análisis del flujo de tráfico vehicular a través de un modelo macroscópico
This work introduces a simple macroscopic model to describe traffic flow in traffic congestion and obtains the equation that relates the characteristic behavior between traffic flow and traffic density, known in the literature as fundamental relationship. Expand


Transport inefficiency in branched-out mesoscopic networks: an analog of the Braess paradox.
Evidence is presented for a counterintuitive behavior of semiconductor mesoscopic networks that is the analog of the Braess paradox encountered in classical networks that can paradoxically induce transport inefficiency that manifests itself in a sizable conductance drop of the network. Expand
The Braess paradox in mechanical, traffic, and other networks
We examine a network of strings and springs that exhibit counter-intuitive behavior. When a support string is cut, the load rises instead of falling. Our experimental and theoretical results lead toExpand
Paradoxical behaviour of mechanical and electrical networks
WE describe here a network of strings and springs in which cutting a string that supports a weight results in a rise of the weight at equilibrium. In an analogous electronic circuit of passiveExpand
Local density of states in mesoscopic samples from scanning gate microscopy
We study the relationship between the local density of states (LDOS) and the conductance variation Delta G in scanning-gate-microscopy experiments on mesoscopic structures as a charged tip scansExpand
Imaging Coulomb islands in a quantum Hall interferometer.
Tuning the magnetic field allows to decrypt the complexity of high-magnetic-field magnetoresistance oscillations, and opens the way to further local-scale manipulations of QH localized states. Expand
Price of anarchy in transportation networks: efficiency and optimality control.
This simulation shows that uncoordinated drivers possibly waste a considerable amount of their travel time, and suggests that simply blocking certain streets can partially improve the traffic conditions. Expand
Imaging and controlling electron transport inside a quantum ring
Traditionally, the understanding of quantum transport, coherent and ballistic1, relies on the measurement of macroscopic properties such as the conductance. Although powerful when coupled toExpand

Imaging electron wave functions inside open quantum rings.
Low temperature imaging of the electron probability density |Psi|(2)(x,y) in embedded mesoscopic quantum rings and tip-induced conductance modulations share the same temperature dependence as the Aharonov-Bohm effect, indicating that they originate from electron wave function interferences. Expand
On a Paradox of Traffic Planning
It is indicated by an example that an extension of the road network may cause a redistribution of the traffic that results in longer individual running times, and whether one street is preferable to another depends not only on the quality of theRoad, but also on the density of the flow. Expand
