We present measurements and simulations of semiconductor-superconductor
heterostructure devices that are consistent with the observation of topological …

The central concept in phononics is the tuning of the phonon dispersion relation, or phonon
engineering, which provides a means of controlling related properties such as group velocity …

In recent decades, two-dimensional materials (2D) such as graphene, black and blue
phosphorenes, transition metal dichalcogenides (eg, WS2 and MoS2), and h-BN have …

Understanding and control of the spin relaxation time T 1 is among the key challenges for
spin-based qubits. A larger T 1 is generally favored, setting the fundamental upper limit to …

We report on combined measurements of heat and charge transport through a single-
electron transistor. The device acts as a heat switch actuated by the voltage applied on the …

We present here our recent results on qubit reset scheme based on a quantum-circuit
refrigerator (QCR). In particular, we use the photon-assisted quasiparticle tunneling through …

Classical and quantum electronic circuits provide ideal platforms to investigate stochastic
thermodynamics, and they have served as a step** stone to realize Maxwell's Demons …

Heat dissipation and thermal management are central challenges in various areas of
science and technology and are critical issues for the majority of nanoelectronic devices. In …

We study a three-terminal setup consisting of a single-level quantum dot capacitively
coupled to a quantum point contact. The point contact connects to a source and drain …

We experimentally demonstrate a recently proposed single-junction quantum-circuit
refrigerator (QCR) as an in situ tunable low-temperature environment for a superconducting …
