High-field fate of the Kitaev quantum spin liquid in -RuCl

K. Imamura, R. Ohno, Y. C. Tsuzuki +15

Kitaev quantum spin liquids (KQSLs) host fractionalized excitations described by itinerant Majorana quasiparticles and gapped fluxes (visons), providing a platform for emerge…

Revealing nonvolatile behaviors in magneto-thermal switching using microstructure-controlled superconducting composites

Keigo Ito, Yui Sakamoto, Hossein Sepehri-Amin +12

Thermal conductivity in a conductor changes by the application of an external magnetic field, which functions as a magneto-thermal switch. For superconductors, a large magneto-ther…
