Defect-Induced Low-Energy Majorana Excitations in the Kitaev Magnet -RuCl
K. Imamura, Y. Mizukami, O. Tanaka +8
The excitations in the Kitaev spin liquid (KSL) can be described by Majorana fermions, which have characteristic field dependence of bulk gap and topological edge modes. In the hig…
Majorana-fermion origin of the planar thermal Hall effect in the Kitaev magnet -RuCl
K. Imamura, S. Suetsugu, Y. Mizukami +11
The field-induced quantum disordered state of layered honeycomb magnet -RuCl is a prime candidate for Kitaev spin liquids hosting Majorana fermions and non-Abelian anyons. R…
Exotic heavy fermion superconductivity in atomically thin CeCoIn films
L. Peng, M. Naritsuka, S. Akutagawa +7
We report an {\it in-situ} scanning tunneling microscopy study of atomically thin films of CeCoIn, a -wave heavy-fermion superconductor. Both hybridization and superconducti…
Quantized and unquantized thermal Hall conductance of Kitaev spin-liquid candidate -RuCl
Y. Kasahara, S. Suetsugu, T. Asaba +5
Despite extensive investigations, a topological state that hosts Majorana edge modes in the magnetic field-induced quantum disordered state of the Kitaev candidate material -RuC…
Topological surface conduction in Kondo insulator YbB
Y. Sato, Z. Xiang, Y. Kasahara +10
Kondo insulators have recently aroused great interest because they are promising materials that host a topological insulator state caused by the strong electron interactions. Moreo…
Intrinsic suppression of topological thermal Hall effect in an exactly solvable quantum magnet
S. Suetsugu, T. Yokoi, K. Totsuka +7
In contrast to electron (fermion) systems, topological phases of charge neutral bosons have been poorly understood despite recent extensive research on insulating magnets. The most…
