Rare-earth borides provide a particularly interesting platform for investigating superconductivity in the presence of magnetic order. The coexistence and competition of these two collective states may lead to behavior that goes beyond the conventional spin-singlet BCS scenario and, under appropriate conditions, may favor unconventional pairing mechanisms. Such systems are of fundamental...

76. Chiral d-wave superconductors for quantum technology: engineering edge currents, vortex-skyrmions and fractional vortices

Chiral superconductors spontaneously break time-reversal symmetry, host a finite Chern number, and have been proposed as a platform for topological quantum computing. In particular, chiral d-wave superconductivity was recently proposed in many different materials, but smoking-gun experimental fingerprints are largely lacking. To solve this, we demonstrate how the spontaneous edge currents and...

70. Latent high-temperature spin-triplet superconductivity of half-metallic manganites - a platform for quantum materials with unique superconducting properties

We discussed a promising way to create artificial quantum materials with high-temperature spin-triplet superconductivity. These are hybrid spin-singlet SC/half-metallic ferromagnetic manganite nanostructures. The experimental results [1] demonstrate an unconventional superconducting proximity effect in SC/hmF manganite nanostructures. Point-contact spectroscopy of proximity-coupled...

84. Metallized DNA: from a biological macromolecule to a functional material

DNA carries the genetic information of living organisms. Understanding its physical properties is essential for elucidating the molecular mechanisms underlying its biological functions and remains a central challenge in biophysics, molecular biology, and biochemistry. At the same time, its availability and unique structural properties make DNA an attractive platform for developing functional...

74. Nonlinear coupling for detection of microwave photon pairs in superconducting circuit QED

Eugene Stolyarov (Bogolyubov Institute for Theoretical Physics)

Photodetector is an essential instrument in quantum optics and is extensively used for various applications across the diverse domain of quantum technologies. A Josephson photomultiplier (JPM) is an on-chip microwave detector that is fully compatible with superconducting circuit QED architecture. Essentially, it is a phase qubit that operates as an absorbing single-photon threshold detector,...

Superconducting magnets are a fundamental component for particle accelerators, enabling the high fields required to bend and focus charged particle beams while keeping power consumption within practical limits. This talk begins with an overview of the field, introducing the role of superconducting magnets in accelerator physics. Then, a very general description on the main conductor materials...
