Charge waves and dynamical signatures of topological phases in Su-Schrieffer-Heeger chains
Tomasz Kwapinski, Marcin Kurzyna, Luis E. F. Foa Torres
We investigate the emergence of charge waves and their temporal dynamics in one-dimensional Su-Schrieffer-Heeger (SSH) topological chains. Contrary to the conventional view that ch…
Time-dependent Andreev bound states of a quantum dot coupled to two superconducting leads
R. Taranko, T. Kwapinski, T. Domanski
Sub-gap transport properties of a quantum dot (QD) coupled to two superconducting and one metallic leads are studied theoretically, solving the time-dependent equation of motion by…
Electron transport across a quantum wire in the presence of electron leakage to a substrate
Tomasz Kwapinski, Sigmund Kohler, Peter Hanggi
We investigate electron transport through a mono-atomic wire which is tunnel coupled to two electrodes and also to the underlying substrate. The setup is modeled by a tight-binding…
Tip apex charging effects in tunneling spectroscopy
T. Kwapinski, M. Jalochowski
The influence of charged STM tip on the electron transport through quantum states on a surface is studied both theoretically and experimentally. The current and the differential co…
Useful equation of tridiagonal matrices in application to electron transport through a quantum wire
T. Kwapinski
In this paper the transmittance through a quantum wire connected with two electron reservoirs is calculated and non-trivial transformation between the evolution operator method and…
Dynamically broken symmetry in periodically gated quantum dots: Charge accumulation and dc-current
T. Kwapinski, S. Kohler, P. Hanggi
Time-dependent electron transport through a quantum dot and double quantum dot systems in the presence of polychromatic external periodic quantum dot energy-level modulations is st…
