Title: Nodal gap structure and order parameter symmetry of the unconventional superconductor UPt ₃

Abstract

Spanning a broad range of physical systems, complex symmetry breaking is widely recognized as a hallmark of competing interactions. This is exemplified in superfluid ³He which has multiple thermodynamic phases with spin and orbital quantum numbers S = 1 and L = 1, that emerge on cooling from a nearly ferromagnetic Fermi liquid. The heavy fermion compound UPt₃ exhibits similar behavior clearly manifest in its multiple superconducting phases. However, consensus as to its order parameter symmetry has remained elusive. Our small angle neutron scattering measurements indicate a linear temperature dependence of the London penetration depth characteristic of nodal structure of the order parameter. Our theoretical analysis is consistent with assignment of its symmetry to an L = 3 odd parity state for which one of the three thermodynamic phases in non-zero magnetic field is chiral.

Broken time-reversal symmetry in the topological superconductor UPt₃

Journal Article Avers, Keenan E. ; Gannon, William J. ; Kuhn, Stephen J. ; ... - Nature Physics

Topological properties of materials are of fundamental as well as practical importance. Of particular interest are unconventional superconductors that break time-reversal symmetry, for which the superconducting state is protected topologically and vortices can host Majorana fermions with potential use in quantum computing. However, in striking contrast to the unconventional A phase of superfluid ³He where chiral symmetry was directly observed, identification of broken time-reversal symmetry of the superconducting order parameter, a key component of chiral symmetry, has presented a challenge in bulk materials. The two leading candidates for bulk chiral superconductors are UPt₃ and Sr₂RuO₄, although evidence for broken time-reversalmore »« less

Vortex states in an unconventional superconductor and the mixed phases of UPt sub 3

Journal Article Tokuyasu, T A ; Hess, D W ; Sauls, J A - Physical Review, B: Condensed Matter; (USA)

Recent experiments on UPt{sub 3} indicate the existence of more than one superconducting phase and an associated unconventional order parameter belonging to a nontrivial representation of the crystal point group {ital D}{sub 6{ital h}}. In this article we consider the Ginzburg-Landau (GL) theory for the vortex states in the two-dimensional {ital E}{sub 1} representation for the order parameter, the representation believed to describe the phases of UPt{sub 3}. One of the zero-field superconducting phases is predicted to break time-reversal symmetry. We show that the lower critical field for vortex nucleation in a ground state with broken time-reversal symmetry exhibits amore »« less

Tunable unconventional kagome superconductivity in charge ordered RbV₃Sb₅ and KV₃Sb₅

Journal Article Guguchia, Zurab ; Mielke III, C. ; Das, D. ; ... - Nature Communications

Unconventional superconductors often feature competing orders, small super fluid density, and nodal electronic pairing. While unusual superconductivity has been proposed in the kagome metals AV₃Sb₅, key spectroscopic evidence has remained elusive. Here we utilize pressure-tuned and ultra-low temperature muon spin spectroscopy to uncover the unconventional nature of super conductivity in RbV₃Sb₅ and KV₃Sb₅. At ambient pressure, we observed time reversal symmetry breaking charge order belowmore »« less

A theory for the superconducting phases of UPt{sub 3}

Journal Article Sauls, J A ; Nordita, Copenhagen - Journal of Low Temperature Physics

The author discusses a phenomenological theory for the multiple superconducting phases of UPt{sub 3} that is based on an order parameter belonging to an orbital 2D representation of the hexagonal point group which is coupled to a weak symmetry breaking field. The author shows that (1) the existing H-T and P-T phase diagrams (including an apparent tetracritical point in the H-T plane for all field orientations), (2) the anisotropy of the upper critical field over the full temperature range, (3) the correlation between superconductivity and basal plane antiferromagnetism and (4) low-temperature power laws in the transport and thermodynamic properties canmore »« less

Effects of Fermi surface anisotropy on unconventional superconductivity in UPt{sub 3}

Journal Article Haran, G ; Hirschfeld, P J ; Sigrist, M - Journal of Low Temperature Physics

The authors discuss the weak-coupling BCS theory of the heavy fermion superconductor UPt{sub 3}, accounting for that system`s anisotropic, multisheeted Fermi surface by expanding the order parameter and pair potential in terms of appropriate basis functions of the irreducible representations of the D{sub 6h} crystal point group. Within a phenomenological model for the electronic structure of UPt{sub 3} chosen to capture the qualitative features of local density functional calculations and de Haas-van Alphen measurements, the authors show how Fermi surface anisotropy can favor pairing in certain symmetry classes, and influence the phase diagram of unconventional superconductors. They also calculate themore »« less
