Low-energy model for doped graphene nanoribbons

J. Ferrer, A. García-Fuente, Y. Yang +2

We analyse in this article the many-body behavior of free-standing doped graphene nanoribbons where the chemical potential lies inside the bulk single-particle bands. We perform an…

Tunable Kondo effect in a bilayer graphene quantum channel

Josep Ingla-Aynés, Serhii Volosheniuk, Talieh S. Ghiasi +5

The interaction between itinerant electrons and localized spins is key to a wide range of electronic phenomena. Of particular interest is the regime where the interacting electrons…

A Single-Molecule Quantum Heat Engine

Serhii Volosheniuk, Riccardo Conte, Eugenia Pyurbeeva +6

Particle-exchange heat engines operate without moving parts or time-dependent driving, relying solely on static energy-selective transport. Here, we realize a particle-exchange qua…

Impact of spin-entropy on the thermoelectric properties of a 2D magnet

Alessandra Canetta, Serhii Volosheniuk, Sayooj Satheesh +11

Heat-to-charge conversion efficiency of thermoelectric materials is closely linked to the entropy per charge carrier. Thus, magnetic materials are promising building blocks for hig…

Implementation of SNS thermometers into molecular devices for cryogenic thermoelectric experiments

Serhii Volosheniuk, Damian Bouwmeester, Chunwei Hsu +2

Thermocurrent flowing through a single-molecule device contains valuable information about the quantum properties of the molecular structure and, in particular, on its electronic a…

Specular electron focusing between gate-defined quantum point contacts in bilayer graphene

Josep Ingla-Aynés, Antonio L. R. Manesco, Talieh S. Ghiasi +4

We report on multiterminal measurements in a ballistic bilayer graphene (BLG) channel where multiple spin and valley-degenerate quantum point contacts (QPCs) are defined by electro…

Probing defect densities at the edges and inside Josephson junctions of superconducting qubits

Alexander Bilmes, Serhii Volosheniuk, Alexey V. Ustinov +1

Tunneling defects in disordered materials form spurious two-level systems which are a major source of decoherence for micro-fabricated quantum devices. For superconducting qubits,…

In-situ bandaged Josephson junctions for superconducting quantum processors

Alexander Bilmes, Alexander K. Händel, Serhii Volosheniuk +2

Shadow evaporation is commonly used to micro-fabricate the key element of superconducting qubits - the Josephson junction. However, in conventional two-angle deposition circuit top…

Quantum Sensors for Microscopic Tunneling Systems

Alexander Bilmes, Serhii Volosheniuk, Jan D. Brehm +2

The anomalous low-temperature properties of glasses arise from intrinsic excitable entities, so-called tunneling Two-Level-Systems (TLS), whose microscopic nature has been baffling…
