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…
Thermodynamic Signatures of Diagonal Nematicity in RbFeAs Superconductor
Y. Mizukami, O. Tanaka, K. Ishida +10
Electronic nematic states with broken rotational symmetry often emerge in correlated materials. In most iron-based superconductors, the nematic anisotropy is oriented in the Fe-Fe…
Thermodynamics of transition to BCS-BEC crossover superconductivity in FeSeS
Y. Mizukami, M. Haze, O. Tanaka +7
The BCS-BEC crossover from strongly overlapping Cooper pairs to non-overlapping composite bosons in the strong coupling limit has been a long-standing issue of interacting many-bod…
Thermodynamic evidence for field-angle dependent Majorana gap in a Kitaev spin liquid
O. Tanaka, Y. Mizukami, R. Harasawa +8
The exactly-solvable Kitaev model of two-dimensional honeycomb magnet leads to a quantum spin liquid (QSL) characterized by Majorana fermions, relevant for fault-tolerant topologic…
Unconventional thermal metallic state of charge-neutral fermions in an insulator
Y. Sato, Z. Xiang, Y. Kasahara +13
Quantum oscillations (QOs) in transport and thermodynamic parameters at high magnetic fields are an unambiguous signature of the Fermi surface, the defining characteristic of a met…
Evidence for s-wave Pairing with Atomic Scale Disorder in the van der Waals Superconductor NaSn2As2
K. Ishihara, T. Takenaka, Y. Miao +8
The recent discovery of superconductivity in NaSnAs with a van der Waals layered structure raises immediate questions on its pairing mechanism and underlying electronic str…
Majorana quantization and half-integer thermal quantum Hall effect in a Kitaev spin liquid
Y. Kasahara, T. Ohnishi, Y. Mizukami +9
The quantum Hall effect (QHE) in two-dimensional (2D) electron gases, which is one of the most striking phenomena in condensed matter physics, involves the topologically protected…
