Spin-polarons and ferromagnetism in doped dilute Wigner-Mott insulators

Kavli Affiliate: Leon Balents | First 5 Authors: Urban F. P. Seifert, Leon Balents, , , | Summary: Moir’e heterostructures of transition metal dichalcogenides exhibit Mott-insulating behaviour both at half-filling as well as at fractional fillings, where electronic degrees of freedom form self-organized Wigner crystal states. An open question concerns magnetic states obtained by lifting […]

The effect of scatter of polymer chain length on strength

Kavli Affiliate: Zhigang Suo | First 5 Authors: Manyuan Tao, Shawn Lavoie, Zhigang Suo, Maria K. Cameron, | Summary: A polymer network fractures by breaking covalent bonds, but the experimentally measured strength of the polymer network is orders of magnitude lower than the strength of covalent bonds. We investigate the effect of statistical variation of […]

The high polarisation of the X-rays from the Black Hole X-ray Binary 4U 1630-47 challenges standard thin accretion disc scenario

Kavli Affiliate: Herman Marshall | First 5 Authors: Ajay Ratheesh, Michal Dovčiak, Henric Krawczynski, Jakub Podgorný, Lorenzo Marra | Summary: Large, energy-dependent X-ray polarisation is observed in 4U 1630-47, a black hole in an X-ray binary, in the high-soft emission state. In this state, X-ray emission is believed to be dominated by a thermal, geometrically […]
