Spin Texture in Quantum Point Contacts in the Presence of Lateral Spin Orbit Coupling
J. Wan, M. Cahay, P. Debray +1
A non-equilibrium Green's function formalism is used to study in detail the ballistic conductance of asymmetrically biased side-gated quantum point contacts (QPCs) in the presence…
Lateral spin-orbit interaction and spin polarization in quantum point contacts
Anh T. Ngo, P. Debray, Sergio Ulloa
We study ballistic transport through semiconductor quantum point contact systems under different confinement geometries and applied fields. In particular, we investigate how the {\…
Possible origin of the 0.5 plateau in the ballistic conductance of quantum point contacts
J. Wan, M. Cahay, P. Debray +1
A non-equilibrium Green function formalism (NEGF) is used to study the conductance of a side-gated quantum point contact (QPC) in the presence of lateral spin-orbit coupling (LSOC)…
All-Electric Quantum Point Contact Spin Valve
P. Debray, J. Wan, S. M. S. Rahman +7
This paper has been withdrawn by the author because in the main text some discussion parts were inadvertently added by mistake.
Coulomb drag between ballistic one-dimensional electron systems
P. Debray, V. Gurevich, R. Klesse +1
The presence of pronounced electronic correlations in one-dimensional systems strongly enhances Coulomb coupling and is expected to result in distinctive features in the Coulomb dr…
Coulomb Drag Between Quasiballistic Quantum Wires: an Indication of Non-Fermi-Liquid Behavior
P. Debray, V. Zverev, R. Klesse +3
The Coulomb drag between two spatially separated, 2 μm long lithographically defined quantum wires has been studied experimentally in the absence of interwire tunneling. The drag r…
Ballistic electron transport in stubbed quantum waveguides: experiment and theory
P. Debray, O. E. Raichev, P. Vasilopoulos +3
We present results of experimental and theoretical investigations of electron transport through stub-shaped waveguides or electron stub tuners (ESTs) in the ballistic regime. Measu…
Bound states and transmission antiresonances in parabolically confined cross structures: influence of weak magnetic fields
R. Akis, P. Vasilopoulos, P. Debray
The ballistic conductance through a device consisting of quantum wires, to which two stubs are attached laterally, is calculated assuming parabolic confining potentials of frequenc…
