Designing high-performance superconductors with nanoparticle inclusions: comparisons to strong pinning theory

Sarah C. Jones, Masashi Miura, Ryuji Yoshida +4

One of the most promising routes for achieving unprecedentedly high critical currents in superconductors is to incorporate dispersed, non-superconducting nanoparticles to control t…

Perspective: Challenges and Transformative Opportunities in Superconductor Vortex Physics

Serena Eley, Andreas Glatz, Roland Willa

In superconductors, the motion of vortices introduces unwanted dissipation that is disruptive to applications. Fortunately, material defects can immobilize vortices, acting as vort…

Inhomogeneous time-reversal symmetry breaking in

Roland Willa, Matthias Hecker, Rafael M. Fernandes +1

We show that the observed time-reversal symmetry breaking (TRSB) of the superconducting state in can be understood as originating from in…

Symmetry-mixed bound-state order: extended degeneracy of -superconductivity in

Roland Willa

We report a fluctuation-driven state of matter that develops near an accidental degeneracy point of two symmetry-distinct primary phases. Due to symmetry mixing, this bound-state o…

Vortex-lattice melting and paramagnetic depairing in the nematic superconductor FeSe

F. Hardy, L. Doussoulin, T. Klein +9

The full H-T phase diagram in the nematic superconductor FeSe is mapped out using specific-heat and thermal-expansion measurements down to 0.7 K and up to 30 T for both field direc…

Vortex phases and glassy dynamics in the highly anisotropic superconductor HgBaCuO

Serena Eley, Roland Willa, Mun K. Chan +2

We present an extensive study of vortex dynamics in a high-quality single crystal of HgBaCuO (Hg1201), a highly anisotropic superconductor that is a model system for st…
