P-wave superconductors hold immense promise for both fundamental physics and practical applications due to their unusual pairing symmetry and potential topological superconductivity. However, the exploration of the p-wave superconductors has proved to be a complex endeavor. Not only are they rare in nature but also the identification of p-wave superconductors has been an arduous task in...

A third monolayer of tin atoms on the semiconductor substrate Si(111) has been shown to become superconducting upon six to ten percent hole doping. Experiments have reported promising results hinting at a superconducting chiral d-wave order parameter [1]. Here we examine Sn/Si(111) by combining most recent ab initio results, quasi-particle interference calculations, state-of-the-art...

Since the early days of Bardeen-Cooper-Schrieffer theory, it has been

predicted that a sufficiently large supercurrent can close the energy
gap in a superconductor and create gapless Bogoliubov quasiparticles
through the Doppler shift of quasiparticle energy due to the Cooper
pair momentum[1]. In this gapless superconducting state, zero-energy
quasiparticles reside on a segment of the... -

High-temperature superconductivity in cuprates is achieved through doping Mott insulators, but the critical process underlying the emergence of superconductivity remains unclear. Combining high-resolution resonant inelastic X-ray scattering (RIXS) and scanning tunneling microscopy (STM), we have investigated Bi2Sr2(Ca,Dy)Cu2O8+δ near the onset of the superconducting dome. Our results indicate...

All cuprate superconductors are based on doping of parent Mott insulators which are collinear antiferromagnets. With doping by holes or electrons the insulator becomes a poor conductor, called a "pseudogap metal" or a "Mott metal", that supports unconventional high temperature superconductivity.
It is well established in neutron scattering that with doping by holes the systems develop...

We demonstrate a direct-write method for creating weak-link Josephson junctions in high-Tc superconducting thin films using thermal scanning probe lithography (t-SPL). A nanoscale heated tip locally modifies the superconductor with sub-10-nm precision, forming constrictions without resists, ion exposure, or multi-step patterning. The resulting nanobridges exhibit Josephson-like...

The recently discovered Ruddlesden-Popper bilayer superconductor La3Ni2O7 has attracted widespread attention due to its high Tc~80 K under a pressure. Soon after that, the trilayer La4Ni3O10 was found to show superconductivity at high pressure too. Our density functional theory calculations indicate that the 3dx2−y2 and 3dz2 orbitals of Ni cations mixing with oxygen 2p orbitals play critical...

Rhombohedral graphene – stacked graphene layers in the ABC configuration – has emerged as an exciting playground for strongly correlated physics and superconductivity. Recent experiments on N-layer rhombohedral graphene reveal signatures of spontaneous time reversal symmetry breaking as well as spin-valley polarised Fermi surfaces. Probes at low temperature reveal several regions of...

The established guiding principle for pulsed laser deposition (PLD) of high-quality YBa₂Cu₃O₇₋ₓ (YBCO) superconducting films suggests that the optimal target-to-substrate distance (TSD) lies near the visible tip of the laser-induced plume, with deviations from this point expected to degrade film properties. We modified our PLD system to allow precise external TSD adjustment over a 110 mm range...

Epitaxial heterostructures combining superconducting YBa₂Cu₃O₇₋δ (YBCO) and ferroelectric BaTiO₃ (BTO) provide a platform to probe interfacial coupling relevant to tunable oxide and quantum devices. In this study, YBCO and BTO thin films were grown on SrTiO₃ (001) by pulsed laser deposition. X-ray diffraction/reflectometry and atomic force microscopy confirm high-quality, c-axis-oriented...

Magnetic systems with momentum-dependent spin splitting provide fertile ground for discovering unconventional phases of matter beyond conventional ferromagnetism and antiferromagnetism.
The recently identified p-wave magnet represents a new class of magnetic order exhibiting odd-parity, time-reversal-symmetric spin splitting in momentum space, offering a promising platform for spintronic...
