Frustration in magnetic materials arising from competing exchange interactions can prevent
the system from adopting long-range magnetic order and can instead lead to a diverse …

Muons are particles with a spin of ½ that can be implanted into a wide range of condensed
matter materials to act as a local probe of the surrounding atomic environment …

Spin liquids are exotic phases of quantum matter that challenge Landau's paradigm of
symmetry-breaking phase transitions. Despite strong exchange interactions, spins do not …

Charge density wave (CDW is one of the most ubiquitous electronic orders in quantum
materials. While the essential ingredients of CDW order have been extensively studied, a …

Quantum spin liquids are highly entangled, disordered magnetic states that are expected to
arise in frustrated Mott insulators and to exhibit exotic fractional excitations such as spinons …

Kondo impurities provide a nontrivial probe to unravel the character of the excitations of a
quantum spin liquid. In the S= 1/2 Kitaev model on the honeycomb lattice, Kondo impurities …

We demonstrate that the single crystal of YCu 3 [OH (D)] 6.5 Br 2.5 (YCOB) is a kagome
Heisenberg antiferromagnet without evident orphan spins (≪ 0.8%). The site mixing …

Designing and characterizing the many-body behaviors of quantum materials represents a
prominent challenge for understanding strongly correlated physics and quantum information …

One favorable situation for spins to enter the long-sought quantum spin liquid (QSL) state is
when they sit on a kagome lattice. No consensus has been reached in theory regarding the …

We solve the problem of a magnetic impurity coupled to a U (1) quantum spin liquid with a
spinon Fermi surface, and we compute the impurity spectral function. Using the slave rotor …
