Description
The Kondo
lattice model
plays a key role in our
understanding of quantum materials,
but a lack of small parameters has posed a
long-standing problem. We
present a 3 dimensional
S$=1/2$ Kondo lattice model describing a spin liquid within an
electron sea. Strong correlations in the spin liquid
are treated exactly, enabling a controlled analytical approach. The
solution describes a plethora of emergent phenomena, including odd-frequency pairing, pair density wave
formation and order fractionalization. The
ground-state state is a pair
density wave with a fractionalized charge $e$,
$S=1/2$ order parameter, formed between electrons and
Majorana fermions.
