Spectral Signatures of Nontrivial Topology in a Superconducting Circuit

Physical Review X
Topology, like symmetry, is a fundamental concept in understanding general properties of physical systems. In condensed matter, nontrivial topology may manifest itself as singular features in the energy spectrum or the quantization of electrical ...

Lattice Mismatch‐Driven In‐Plane Strain Engineering for Enhanced Upper Critical Fields in Mo2N Superconducting Thin Films

Advanced Materials Interfaces, Volume 12, Issue 22, November 22, 2025.
Compressive strain in Mo2N thin films on MgO substrates significantly enhances electron‐phonon coupling, resulting in a ∼25% increase in the upper critical field compared to films on Al2O3 substrate. This finding demonstrates an effective strategy for achieving higher‐performance superconducting devices by utilizing strain as a tunable parameter to ...

Topologically protected loop flows in high voltage AC power grids

New Journal of Physics, 2016
Geographical features such as mountain ranges or big lakes and inland seas often result in large closed loops in high voltage AC power grids. Sizable circulating power flows have been recorded around such loops, which take up transmission line capacity ...

Superconductivity in Hourglass Dirac Chain Metals (Ti, Hf)IrGe

Advanced Science, Volume 12, Issue 43, November 20, 2025.
We report the discovery of ternary germanide superconductors MIrGe (M = Ti, Hf) that host hourglass Dirac chains protected by nonsymmorphic symmetry. These compounds exhibit bulk type‐II superconductivity with fully gapped states and preserved time‐reversal symmetry, as confirmed by µSR measurements.

$\delta$-biased Josephson tunnel junctions

, 2009
The behavior of a long Josephson tunnel junction drastically depends on the distribution of the dc bias current. We investigate the case in which the bias current is fed in the central point of a one-dimensional junction. Such junction configuration has been recently used to detect the persistent currents circulating in a superconducting loop ...

Thermoelectric Processes of Quantum Normal‐Superconductor Interfaces

Annalen der Physik, Volume 537, Issue 11, November 2025.
Recent advances on using mesoscopic normal‐superconductor junctions for the thermoelectric effect is reviewed. A theoretical framework is presented for multiterminal configurations exploiting properties characterised by the interplay of the system reduced dimensionality and superconducting correlations.

Interaction of Josephson and magnetic oscillations in Josephson tunnel junctions with a ferromagnetic layer [PDF]

, 2011
We study the dynamics of Josephson junctions with a thin ferromagnetic layer F [superconductor-ferromagnet-insulator-ferromagnet-superconductor (SFIFS) junctions]. In such junctions, the phase difference $\phi$ of the superconductors and magnetization $M$

Nanoscale spin ordering and spin screening effects in tunnel ferromagnetic Josephson junctions

Communications Materials
Magnetic Josephson junctions (MJJs) have emerged as a prominent playground to explore the interplay between superconductivity and ferromagnetism. A series of fascinating experiments have revealed striking phenomena at the superconductor/ferromagnet (S/F)

Cuprate Twistronics for Quantum Hardware

Advanced Quantum Technologies, Volume 8, Issue 11, November 2025.
This review bridges decades of foundational research with emerging fabrication techniques such as molecular beam epitaxy and cryogenic stacking. By enabling control over electronic correlations and symmetry in twisted cuprate heterostructures, it highlights how cuprate twistronics could open new paths to overcome decoherence and scalability challenges ...

Shapiro steps in Josephson junctions with alternating critical current density

, 2007
We treat theoretically Shapiro steps in tunnel Josephson junctions with spatially alternating critical current density. Explicit analytical formulas for the width of the first integer (normal) and half-integer (anomalous) Shapiro steps are derived for ...
