L'ajout d'un second canal Kondo dans les matériaux à fermions lourds révèle de nouvelles phases exotiques brisant la symétrie et associées au développement de la cohérence Kondo. Nous passons en revue dans cet article deux de ces phases, l'ordre hastatique associé à des doublets fondamentaux non Kramers, où la nature double-canal du couplage Kondo est assurée par des fluctuations de valence vers un doublet de Kramers excité, et la « supraconductivité à paire composite », où les deux canaux diffèrent d'une charge 2e et peuvent être vus comme des fluctuations de valence virtuelles vers un doublet de pseudo-isospin. Les similarités et différences entre ces deux ordres sont discutées, ainsi que leurs possibles réalisations dans des matériaux à base d'actinides et de terres rares, comme URu2Si2 et NpPd5Al2.

Adding a second Kondo channel to heavy fermion materials reveals new exotic symmetry breaking phases associated with the development of Kondo coherence. In this paper, we review two such phases, the “hastatic order” associated with non-Kramers doublet ground states, where the two-channel nature of the Kondo coupling is guaranteed by virtual valence fluctuations to an excited Kramers doublet, and “composite pair superconductivity,” where the two channels differ by charge 2e and can be thought of as virtual valence fluctuations to a pseudo-isospin doublet. The similarities and differences between these two orders will be discussed, along with possible realizations in actinide and rare earth materials like URu2Si2 and NpPd5Al2.
