Summary: This study demonstrates the presence of large thermoelectric effects in superconducting tunnel junctions when there is a significant thermal gradient. By integrating these junctions into a Josephson interferometer, a bipolar thermoelectric Josephson engine capable of generating phase-tunable electric power is realized. These findings are expected to have applications in superconducting quantum technologies.

Summary: The study thoroughly investigates the thermoelectric performance of a topological Josephson nonlocal heat engine, exploring how different triggers affect the nonlocal thermoelectric effects and considering possible experimental nonidealities. It discusses the interplay between Doppler shift and Andreev interferometry for different operating regimes, and highlights high nonlocal Seebeck coefficients that could be detectable even against spurious local effects.

Summary: In this study, the thermodynamic properties of topological Josephson junctions were investigated using a QSH insulator-based junction as an example. It was proposed that phase-dependent measurements of heat capacity could be used to demonstrate topological features and distinguish between topological and trivial junctions. The results showed a pronounced double-peak feature in the heat capacity's phase dependence, with the 4pi periodicity observed in the superconducting phase difference at short time scales.

Summary: Josephson radiation is a useful signature for detecting Majorana zero modes in topological superconductors. The quantum dynamics of the Majorana two-level system induce oscillatory patterns in the Josephson emission spectra, which can be well described by Bessel functions. These Bessel radiation patterns exist for a wide range of junction parameters, as verified by numerical simulations.

Summary: The study reveals that uniform magnetization in three-dimensional topological insulator Josephson junctions can induce asymmetry in the Andreev spectrum, leading to Majorana modes and the Josephson Hall effect. Magnetic control and gating can enable significant Josephson Hall currents compared to longitudinal currents.

Summary: In plane wave spacetimes, gravitational waves passing through can cause a precession angle deviation between two freefalling gyroscopes, which is closely related to the standard velocity memory effect. The initial conditions, such as separation velocity or displacement, between the gyroscopes affect the angle deviation. This result can be understood as a special relativistic consequence of velocity memory. The calculated evolutions of the angle deviation show that in extreme circumstances, the angle deviation produced by a rotating compact binary source can be on the order of 10-14 radians. Therefore, this gravitational wave-induced memory effect is likely to be detected in the future.

Summary: This work presents prototypes of a phase shifter utilizing Josephson phase shift generated by coreless superconducting vortices. The small size of the vortex enables broad-range tunability through nanoscale manipulation in a micron-size array of vortex traps. The phase shift in the device can be reconfigured between quantized states in a broad [-3 pi +3 pi] range with just a few vortex traps.

Summary: In this study, we investigate the phase-dependent charge and heat current in short Josephson junctions (JJs) formed at helical edge states of two-dimensional topological insulators. The transmission spectra exhibit an asymmetry around the zero energy for all finite phases, except for a specific phase value. The asymmetry induced by phase plays a significant role in the charge and heat current, but the current amplitudes are sensitive to the junction size.

Summary: We propose a universal mechanism for the Josephson diode effect in short Josephson junctions, which arises from finite Cooper pair momentum and simultaneous breaking of inversion and time-reversal symmetries. The diode efficiency is up to 40% with an asymmetry between the critical currents in opposite directions of approximately 230%. The mechanism is explained by the Doppler shift of the Andreev bound state energies and the phase-independent asymmetric current from the continuum. We also introduce a simple scheme for achieving finite-momentum pairing without relying on spin-orbit coupling, expanding the platforms for observing supercurrent diode effects.

Summary: Josephson tunnel junctions exhibit a supercurrent proportional to the sine of the superconducting phase difference. Voltage pulses with sharp temporal variations significantly influence the term proportional to the cosine of the phase difference. The nonequilibrium fractional Josephson effect arises from the interference of nonequilibrium virtual quasiparticle excitations, and it is independent of the ground state fermion parity in topological Josephson junctions.

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.
