Triplet-blockaded Josephson supercurrent in double quantum dots
Daniël Bouman, Ruben J. J. van Gulik, Gorm Steffensen +7
Serial double quantum dots created in semiconductor nanostructures provide a versatile platform for investigating two-electron spin quantum states, which can be tuned by electrosta…
Transport signatures of an Andreev molecule in a quantum dot -- superconductor -- quantum dot setup
Zoltán Scherübl, András Pályi, Szabolcs Csonka
Hybrid devices combining quantum dots with superconductors are important building blocks of conventional and topological quantum-information experiments. A requirement for the succ…
Floquet spectroscopy of a strongly driven quantum dot charge qubit with a microwave resonator
J. V. Koski, A. J. Landig, A. Pályi +7
We experimentally investigate a strongly driven GaAs double quantum dot charge qubit weakly coupled to a superconducting microwave resonator. The Floquet states emerging from stron…
Impurity-assisted electric control of spin-valley qubits in monolayer MoS
G. Széchenyi, L. Chirolli, A. Pályi
We theoretically study a single-electron spin-valley qubit in an electrostatically defined quantum dot in a transition metal dichalcogenide monolayer, focusing on the example of Mo…
Hyperfine and spin-orbit coupling effects on decay of spin-valley states in a carbon nanotube
T. Pei, A. Pályi, M. Mergenthaler +5
The decay of spin-valley states is studied in a suspended carbon nanotube double quantum dot via leakage current in Pauli blockade and via dephasing and decoherence of a qubit. Fro…
Valley-enhanced fast relaxation of gate-controlled donor qubits in silicon
Péter Boross, Gábor Széchenyi, András Pályi
Gate control of donor electrons near interfaces is a generic ingredient of donor-based quantum computing. Here, we address the question: how is the phonon-assisted qubit relaxation…
Orbital hyperfine interaction and qubit dephasing in carbon nanotube quantum dots
Gábor Csiszár, András Pályi
Hyperfine interaction (HF) is of key importance for the functionality of solid-state quantum information processing, as it affects qubit coherence and enables nuclear-spin quantum…
Current hot spot in the spin-valley blockade in carbon nanotubes
Gábor Széchenyi, András Pályi
We present a theoretical study of the spin-valley blockade transport effect in a double quantum dot defined in a straight carbon nanotube. We find that intervalley scattering due t…
Electronic standing waves on the surface of the topological insulator Bi2Te3
P. Rakyta, A. Palyi, J. Cserti
A line defect on a metallic surface induces standing waves in the electronic local density of states (LDOS). Asymptotically far from the defect, the wave number of the LDOS oscilla…
Disorder-mediated electron valley resonance in carbon nanotube quantum dots
András Pályi, Guido Burkard
We propose a scheme for coherent rotation of the valley isospin of a single electron confined in a carbon nanotube quantum dot. The scheme exploits the ubiquitous atomic disorder o…
Electron Flow in Circular n-p Junctions of Bilayer Graphene
Cs. Peterfalvi, A. Palyi, J. Cserti
We present a theoretical study of electron wave functions in ballistic circular n-p junctions of bilayer graphene. Similarly to the case of a circular n-p junction of monolayer gra…
Spin-dependent electron-impurity scattering in two-dimensional electron systems

We present a theoretical study of elastic spin-dependent electron scattering caused by a charged impurity in the vicinity of a two-dimensional electron gas. We find that the symmet…
Caustics due to Negative Refractive Index in Circular Graphene p-n Junctions
Jozsef Cserti, Andras Palyi, Csaba Peterfalvi
We show that the wavefunctions form caustics in circular graphene p-n junctions which in the framework of geometrical optics can be interpreted with negative refractive index.
