Broadband merged-element Josephson parametric amplifier
Broadband quantum-limited amplifiers are essential for quantum information processing, yet challenges in design and fabrication continue to hinder their widespread applications. Here, we introduce the broadband merged-element Josephson parametric amplifier in which the discrete parallel capacitor is directly integrated with the Josephson junctions. This merged-element design eliminates the shortcomings of discrete capacitors, simplifying the fabrication process, reducing the need for high-preci…

Jag går igenom en mängd dåliga och rent felaktiga argument som är vanliga kring talangutveckling idag. Framför allt blir det fokus på saker som Patrik Brenning påstår i boken så vinner vi igen.

Thermomodulated intrinsic Josephson effect in Kagome CsV3Sb5
Superconducting chiral domains associated with a time-reversal symmetry-breaking order parameter have garnered significant attention in Kagome systems. In this work, we demonstrate both the intrinsic direct-current and alternating-current Josephson effects in the nanoplates of the vanadium-based Kagome material CsV3Sb5, as evidenced by Fraunhofer-like patterns and Shapiro steps. Moreover, both the Fraunhofer-like patterns and Shapiro steps are modulated by thermal cycling, suggesting that the J…

Electric-Field Control of Josephson Oscillations in Dipolar Bose-Einstein Condensates
We study the dynamic behavior of a Bose-Einstein condensate (BEC) with dipolar interactions when the influence of external electric fields affects the coherent tunneling properties. Here, we propose a tunable platform based on BECs where Josephson oscillations can be engineered and modulated through external electric fields. We develop a theoretical and numerical frame-work that reveals how electric fields affect intercondensate tunneling, phase dynamics, and collective excitations. By employin…

Considering contact forces during the formation of planetesimals by gravitational collapse: mutual orbits, spin states, and shapes
In this work, we apply a soft-sphere discrete element method (SSDEM) within the PKDGRAV N-body integrator to investigate the formation of planetesimal systems through the gravitational collapse of clouds of super-particles. Previously published numerical models have demonstrated that the gravitational collapse of pebble clouds is an efficient pathway to produce binary planetesimal systems. However, such investigations were limited by their use of a perfect-merger and inflated-radii super-partic…

Low barrier ZrO$_x$-based Josephson junctions
The Josephson junction is a crucial element in superconducting devices, and niobium is a promising candidate for the superconducting material due to its large energy gap relative to aluminum. AlO$_x$ has long been regarded as the highest quality oxide tunnel barrier and is often used in niobium-based junctions. Here we propose ZrO$_x$ as an alternative tunnel barrier material for Nb electrodes. We theoretically estimate that zirconium oxide has excellent oxygen retention properties and experime…

On the theory of supermodulation of the superconducting order parameter by supermodulation of the apex distance in optimally doped Bi$_2$Sr$_2$CaCu$_2$O$_{8+x}$
Recently using Scanning Josephson Tunneling Microscopy (SJTM) in the group of Séamus Davis a super-modulation of the superconducting order parameter induced by super-modulation of the distance $δ$ between planar Cu and apical O was observed in [O'Mahony et al, On the electron pairing mechanism of copper-oxide high temperature superconductivity, PNAS Vol. 119(37), e2207449119 (2022)]. The authors conclude: "concurrence of prediction from strong correlation theory... with these observations ind…
