InAs-Al Hybrid Devices Passing the Topological Gap Protocol
Morteza Aghaee, Arun Akkala, Zulfi Alam +124
We present measurements and simulations of semiconductor-superconductor heterostructure devices that are consistent with the observation of topological superconductivity and Majora…
Tkwant: a software package for time-dependent quantum transport
Thomas Kloss, Joseph Weston, Benoit Gaury +3
Tkwant is a Python package for the simulation of quantum nanoelectronics devices to which external time-dependent perturbations are applied. Tkwant is an extension of the Kwant pac…
The HANDE-QMC project: open-source stochastic quantum chemistry from the ground state up
James S. Spencer, Nick S. Blunt, Seonghoon Choi +15
Building on the success of Quantum Monte Carlo techniques such as diffusion Monte Carlo, alternative stochastic approaches to solve electronic structure problems have emerged over…
Cooperative Charge Pumping and Enhanced Skyrmion Mobility
Adel Abbout, Joseph Weston, Xavier Waintal +1
The electronic pumping arising from the steady motion of ferromagnetic skyrmions is investigated by solving the time evolution of the Schrodinger equation implemented on a tight-bi…
Transient and Sharvin resistances of Luttinger liquids
Thomas Kloss, Joseph Weston, Xavier Waintal
Although the intrinsic conductance of an interacting one-dimensional system is renormalized by the electron-electron correlations, it has been known for some time that this renorma…
Towards Realistic Time-Resolved Simulations of Quantum Devices
Joseph Weston, Xavier Waintal
We report on our recent efforts to perform realistic simulations of large quantum devices in the time domain. In contrast to d.c. transport where the calculations are explicitly pe…
A linear-scaling source-sink algorithm for simulating time-resolved quantum transport and superconductivity
Joseph Weston, Xavier Waintal
We report on a "source-sink" algorithm which allows one to calculate time-resolved physical quantities from a general nanoelectronic quantum system (described by an arbitrary time-…
Probing (topological) Floquet states through DC transport
Michel Fruchart, Pierre Delplace, Joseph Weston +2
We consider the differential conductance of a periodically driven system connected to infinite electrodes. We focus on the situation where the dissipation occurs predominantly in t…
Manipulating Andreev and Majorana Bound States with microwaves
Joseph Weston, Benoit Gaury, Xavier Waintal
We study the interplay between Andreev (Majorana) bound states that form at the boundary of a (topological) superconductor and a train of microwave pulses. We find that the extra d…
AC Josephson effect without superconductivity
Benoit Gaury, Joseph Weston, Xavier Waintal
Superconductivity derives its most salient features from the coherence of its macroscopic wave function. The associated physical phenomena have now moved from exotic subjects to fu…
Classical and quantum spreading of a charge pulse
Benoit Gaury, Joseph Weston, Christoph Groth +1
With the technical progress of radio-frequency setups, high frequency quantum transport experiments have moved from theory to the lab. So far the standard theoretical approach used…
Stopping electrons with radio-frequency pulses in the quantum Hall regime
Benoit Gaury, Joseph Weston, Xavier Waintal
Most functionalities of modern electronic circuits rely on the possibility to modify the path fol- lowed by the electrons using, e.g. field effect transistors. Here we discuss the…
Numerical simulations of time resolved quantum electronics
Benoit Gaury, Joseph Weston, Matthieu Santin +3
This paper discusses the technical aspects - mathematical and numerical - associated with the numerical simulations of a mesoscopic system in the time domain (i.e. beyond the singl…
