Heat Conduction and Energy Relaxation in an InAs Nanowire Approaching the Clean One-Dimensional Limit
Subhomoy Haldar, Diego Subero, Mukesh Kumar +5
We investigate heat conduction and energy relaxation in an InAs semiconductor nanowire using a hybrid semiconductor-superconductor architecture. Local electronic temperatures are m…
Revisiting dissipation-driven phase transition in a Josephson junction
Diego Subero, Yu-Cheng Chang, Miguel Monteiro +2
Despite extensive experimental and theoretical work over several decades, Schmid-Bulgadaev quantum phase transition remains a subject of debate. Here we revisit this problem by per…
Millikelvin Si-MOSFETs for Quantum Electronics
Nikolai Yurttagül, Markku Kainlauri, Jan Toivonen +7
Large power consumption of silicon CMOS electronics is a challenge in very-large-scale integrated circuits and a major roadblock to fault-tolerant quantum computation. Matching the…
Strong-coupling quantum thermodynamics using a superconducting flux qubit
Rishabh Upadhyay, Bayan Karimi, Diego Subero +4
Thermodynamics in quantum circuits aims to find improved functionalities of thermal machines, highlight fundamental phenomena peculiar to quantum nature in thermodynamics, and poin…
Applications of Superconductor-Normal Metal Interfaces
S. A. Lemziakov, B. Karimi, S. Nakamura +8
The importance and non-trivial properties of superconductor normal metal interfaces was discovered by Alexander Fyodorovich Andreev more than 60 years ago. Only much later these hy…
Photonic heat transport through a Josephson junction in a resistive environment
A. Levy Yeyati, D. Subero, J. Pekola +1
Motivated by recent experiments (Subero et. al. Nature Comm. , 7924 (2023)) we analyze photonic heat transport through a Josephson junction in a dissipative environment. F…
