Highly tunable magnetic phases in transition metal dichalcogenide Fe$_{1/3+δ}$NbS$_2$

Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Shan Wu, Zhijun Xu, Shannon C. Haley, Sophie F. Weber, Arany Acharya | Summary: Layered transition metal dichalcogenides (TMDCs) host a plethora of interesting physical phenomena ranging from charge order to superconductivity. By introducing magnetic ions into 2H-NbS$_2$, the material forms a family of magnetic intercalated […]

Enhanced spin-orbit coupling and orbital moment in ferromagnets by electron correlations

Kavli Affiliate: Bo Gu | First 5 Authors: Ze Liu, Jing-Yang You, Bo Gu, Sadamichi Maekawa, Gang Su | Summary: In atomic physics, the Hund rule says that the largest spin and orbital state is realized due to the interplay of the spin-orbit coupling (SOC) and the Coulomb interactions. Here, we show that in ferromagnetic […]

Earth as a transducer for dark-photon dark-matter detection

Kavli Affiliate: Peter W. Graham | First 5 Authors: Michael A. Fedderke, Peter W. Graham, Derek F. Jackson Kimball, Saarik Kalia, | Summary: We propose the use of the Earth as a transducer for ultralight dark-matter detection. In particular we point out a novel signal of kinetically mixed dark-photon dark matter: a monochromatic oscillating magnetic […]

Nickelate superconductivity without rare-earth magnetism: (La,Sr)NiO$_{2}$

Kavli Affiliate: Lena F. Kourkoutis | First 5 Authors: Motoki Osada, Bai Yang Wang, Berit H. Goodge, Shannon P. Harvey, Kyuho Lee | Summary: The observation of superconductivity in infinite layer nickelate (Nd,Sr)NiO$_{2}$ thin films has led to rapid theoretical and experimental investigations of these copper-oxide-analogue systems [1-15]. Superconductivity has also been found in (Pr,Sr)NiO$_{2}$ […]

Renormalization and non-renormalization of scalar EFTs at higher orders

Kavli Affiliate: Tom Melia | Summary:We renormalize massless scalar effective field theories (EFTs) to higher loop orders and higher orders in the EFT expansion. To facilitate EFT calculations with the R* renormalization method, we construct suitable operator bases using Hilbert series and related ideas in commutative algebra and conformal representation theory, including their novel application […]

Symmetric $mathrmU(1)$ and $mathbbZ_2$ spin liquids on the pyrochlore lattice

Kavli Affiliate: Leon Balents | Summary:The geometrically frustrated 3D pyrochlore lattice has been long predicted to host a quantum spin liquid, an intrinsic long-range entangled state with fractionalized excitations. To date, most proposals for pyrochlore materials have focused on quantum spin ice, a $mathrmU(1)$ quantum spin liquid whose only low energy excitations are emergent photons […]
