Ultrasound evidence for multicomponent superconducting order parameter in Ba $_{1 - x}$ K $_{x}$ Fe $_{2}$ As $_{2}$ with electron quadrupling phase

Chris Halcrow, Ilya Shipulin, Federico Caglieris +6

Experiments have pointed to the formation of the electron quadrupling condensate in Ba $_{1 - x}$ K $_{x}$ Fe $_{2}$ As $_{2}$ at $x \sim 0.8$ . The state spontaneously breaks time-reversal symmet…

Ultrasound response to time-reversal symmetry breaking below the superconducting phase transition

Chris Halcrow, Paul Leask, Egor Babaev

Ultrasound attenuation is a powerful probe of symmetry-breaking phenomena in superconductors. In this work, we develop a framework to model the ultrasound response of multi-compone…
