|
71 |
+ \ system\nis renormalized by the electron-electron correlations, it has been known\ |
|
72 |
+ \ for\nsome time that this renormalization is washed out by the presence of the\n\ |
|
73 |
+ (non-interacting) electrodes to which the wire is connected. Here, we study the\n\ |

|
75 |
+ across the wire and we measure the current before it has enough time to reach\n\ |

76 |

+ abstract: "Most functionalities of modern electronic circuits rely on the possibility\ |
|
256 |
+ \ to\nmodify the path fol- lowed by the electrons using, e.g. field effect\ntransistors.\ |
|
257 |
+ \ Here we discuss the interplay between the modification of this\npath and the\ |
|
258 |
+ \ quantum dynamics of the electronic flow. Specifically, we study\nthe propagation\ |
|
259 |
+ \ of charge pulses through the edge states of a two-dimensional\nelectron gas\ |
|
260 |
+ \ in the quantum Hall regime. By sending radio-frequency (RF)\nexcitations on\ |
|
261 |
+ \ a top gate capacitively coupled to the electron gas, we\nmanipulate these edge\ |
|
262 |
+ \ state dynamically. We find that a fast RF change of the\ngate voltage can stop\ |
|
263 |
+ \ the propagation of the charge pulse inside the sample.\nThis effect is intimately\ |
|
264 |
+ \ linked to the vanishing velocity of bulk states in\nthe quantum Hall regime\ |
|
265 |
+ \ and the peculiar connection between momentum and\ntransverse confinement of\ |
|
266 |
+ \ Landau levels. Our findings suggest new possibilities\nfor stopping, releasing\ |
|
267 |
+ \ and switching the trajectory of charge pulses in\nquantum Hall systems." |

+ abstract: "This paper discusses the technical aspects - mathematical and numerical\ |
|
282 |
+ \ -\nassociated with the numerical simulations of a mesoscopic system in the time\n\ |
|
283 |
+ domain (i.e. beyond the single frequency AC limit). After a short review of the\n\ |
|
284 |
+ state of the art, we develop a theoretical framework for the calculation of\n\ |
|
285 |
+ time resolved observables in a general multiterminal system subject to an\narbitrary\ |
|
286 |
+ \ time dependent perturbation (oscillating electrostatic gates, voltage\npulses,\ |
|
287 |
+ \ time-vaying magnetic fields) The approach is mathematically equivalent\nto (i)\ |
|
288 |
+ \ the time dependent scattering formalism, (ii) the time resolved Non\nEquilibrium\ |
|
289 |
+ \ Green Function (NEGF) formalism and (iii) the partition-free\napproach. The\ |
|
290 |
+ \ central object of our theory is a wave function that obeys a\nsimple Schrodinger\ |
|
291 |
+ \ equation with an additional source term that accounts for\nthe electrons injected\ |
|
292 |
+ \ from the electrodes. The time resolved observables\n(current, density. . .)\ |
|
293 |
+ \ and the (inelastic) scattering matrix are simply\nexpressed in term of this\ |
|
294 |
+ \ wave function. We use our approach to develop a\nnumerical technique for simulating\ |
|
295 |
+ \ time resolved quantum transport. We find\nthat the use of this wave function\ |
|
296 |
+ \ is advantageous for numerical simulations\nresulting in a speed up of many orders\ |
|
297 |
+ \ of magnitude with respect to the direct\nintegration of NEGF equations. Our\ |
|
298 |
+ \ technique allows one to simulate realistic\nsituations beyond simple models,\ |
|
299 |
+ \ a subject that was until now beyond the\nsimulation capabilities of available\ |
|
300 |
+ \ approaches." |
