Summary: This study demonstrates a tunable parametric amplifier using a graphene Josephson junction, with the ability to tune its working frequency widely through gate voltage. The amplifier exhibits a gain exceeding 20 dB and noise performance close to the standard quantum limit. These findings expand the toolset for electrically tunable superconducting quantum circuits and offer opportunities for the development of quantum technologies such as quantum computing and quantum sensing, as well as for fundamental science.

Summary: In this study, we explore the vortex dynamics in a two-dimensional Josephson junction array. We observe that the minima of differential resistance undergo a transition and become local maxima at integer and half-integer flux quanta per plaquette. We also observe differences in the transition behavior between the superconducting and anomalous metal phases. Additionally, we find that the transitions show an overall even-odd pattern of skewing around integer f values, which we attribute to vortex commensuration in the square array.

Summary: This study theoretically investigates the Josephson current through a single semiconductor quantum dot with Majorana bound states. The strength and period of the Josephson current can be controlled by adjusting the coupling between the quantum dot and a third junction. The results suggest potential applications in adjusting current density in superconducting coated conductors technologies.

Summary: This paper proposes a tunable thermal emitter consisting of metal-insulator-metal (MIM) plasmonic metamaterial based on phase-change material Ge2Sb2Te5 (GST) to achieve tunable control of thermal radiation in wavelength ranges from 3 μm to 14 μm. The emitter possesses near unity emissivity at 6.3 μm wavelength for increased radiation heat dissipation, maintaining thermal stability. The emitter also offers thermal camouflage in the atmospheric window range of 3-5 μm for various background temperatures and environmental backgrounds.

Summary: The study explores the use of subwavelength resonators to overcome the challenges in exciting JPR in high-temperature superconductor films. A tunable THz metamaterial made from Tl-2212 HTS film showed resonant excitation of Josephson plasmon, with simulation results indicating the scattering of subwavelength resonators providing the necessary electric field component. The coupling between JPR and metamaterial resonance modes was observed, showing potential for tunable and nonlinear THz devices.

Summary: The Josephson diode effect is observed in three-terminal Josephson devices based on InAs quantum well electron gas proximitized by an epitaxial aluminum layer. The diode efficiency in these devices can be tuned by a magnetic field or electrostatic gating. It is also found that the diode effect is inherent in multi-terminal Josephson devices, providing a scalable approach for potential applications.

Summary: Recent studies have shown that the critical currents of metallic superconducting nanowires and Dayem bridges can be locally tuned using a gate voltage. In this study, a gate-tunable Josephson junction structure was reported, constructed from a three-dimensional niobium nanobridge junction with a voltage gate on top. The critical current of this structure can be tuned to zero by increasing the gate voltage, and the flux modulation generated by Josephson interference can also be tuned in a similar manner. Therefore, this gate-tunable Josephson junction structure shows promise for high integration level superconducting circuit fabrication.

Summary: In this study, it is found that the thermal phase equivalent conductance can be significantly enhanced and change signs in a Josephson junction system composed of two superconductors connected to a semiconductor quantum dot. This result arises from the new states formed near the Fermi level of the superconductors due to the hybridization between the quantum dot and the Majorana bound states. The sign change of the thermal phase equivalent conductance provides strong evidence for the existence of Majorana bound states.

Summary: By optimizing the geometry of the electromagnetic cavity and the ferromagnet, coherent exchange of information between cavity photons and ferromagnetic spin excitations can be achieved at high speeds. The fundamental frequency of the magnonic resonator is also influenced by the geometry of the ferromagnet. Experimental results show that the light-matter coupling strength can be estimated using open transmission lines or resonant cavities, with good agreement between the two methods. A theoretical framework based on electromagnetic and micromagnetic simulations successfully explains the experimental results.

Summary: This study theoretically investigates quantum size effects in the magnetic response of spherical metallic nanoparticles, such as gold. It demonstrates that below a critical magnetic field, the magnetic response is diamagnetic, while above this field, there are sharp increases in magnetization. The study also proposes two experimental methods for detecting these effects using superconducting quantum interference devices.
