Coexisting localized and itinerant gapless excitations in a quantum spin liquid candidate 1T-TaS
H. Murayama, Y. Sato, X. Z. Xing +6
To reveal the nature of elementary excitations in a quantum spin liquid (QSL), we measured low temperature thermal conductivity and specific heat of 1T-TaS, a QSL candidate mat…
Cold exciton electroluminescence from air-suspended carbon nanotube split-gate devices
N. Higashide, M. Yoshida, T. Uda +2
Electroluminescence from individual carbon nanotubes within split-gate devices is investigated. By characterizing the air-suspended nanotubes with photoluminescence spectroscopy, c…
Unveiling Majorana Quasiparticles by a Quantum Phase Transition: Proposal of a Current Switch
F. A. Dessotti, L. S. Ricco, Y. Marques +6
We propose a theoretical approach based on an interferometer composed by two quantum dots asymmetrically coupled to isolated Majorana quasiparticles (MQPs), lying on the edges of t…
Fano interference and a slight fluctuation of the Majorana hallmark
A. C. Seridonio, E. C. Siqueira, F. A. Dessotti +2
According to the Phys. Rev. B 84, 201308(R) (2011), an isolated Majorana state bound to one edge of a long enough Kitaev chain in the topological phase and connected to a quantum d…
Universal zero-bias conductance through a quantum wire side-coupled to a quantum dot
A. C. Seridonio, M. Yoshida, L. N. Oliveira
A numerical renormalization-group study of the conductance through a quantum wire side-coupled to a quantum dot is reported. The temperature and the dot-energy dependence of the co…
Spin Singlet Formation from S = 1/2 Tetrahedral Clusters
T. Waki, Y. Kajinami, Y. Tabata +4
Muon spin relaxation (SR) and nuclear magnetic resonance (NMR) experiments revealed that the spin singlet state with an excitation gap of 200 K is realized from …
