“…What suppresses κ xx could arise from the mutual scattering between the magnetic excitations and the the phonons. In fact, similar field dependence of thermal conductivity κ xx has been observed in other rare-earth systems such as [67][68][69] that the spinphonon scattering is the cause. The Yb local moment, that is a spin-orbit-entangled object, involves the orbital degree of freedom.…”

Motivated by the recent progress on the spin-orbit-coupled triangular lattice spin liquid candidate YbMgGaO4, we carry out a systematic projective symmetry group analysis and mean-field study of candidate U(1) spin liquid ground states. Due to the spin-orbital entanglement of the Yb moments, the space group symmetry operation transforms both the position and the orientation of the local moments, and hence brings different features for the projective realization of the lattice symmetries from the cases with spin-only moments. Among the eight U(1) spin liquids that we find with the fermionic parton construction, only one spin liquid state, that was proposed and analyzed in Yao Shen, et. al., Nature 540, 559-562 (2016) and labeled as U1A00 in the present work, stands out and gives a large spinon Fermi surface and provides a consistent explanation for the spectroscopic results in YbMgGaO4. Further connection of this spinon Fermi surface U(1) spin liquid with YbMgGaO4 and the future directions are discussed. Finally, our results may apply to other spinorbit-coupled triangular lattice spin liquid candidates, and more broadly, our general approach can be well extended to spin-orbit-coupled spin liquid candidate materials.

“…The limits of detection of our electrochemical biosensors for detecting specific miRNAs are summarized in Table 1 which also contains a comparison to various current miRNA detection biosensors. It can be seen from Table 1 that the developed electrochemical sensor has a suitable detection limit 50–57 . As a result, the proposed electrochemical biosensors exhibited suitable sensitivity to specific miRNA detection.…”

We present electrochemical biosensors for the analysis of a target miR-155 that work through the formation of miRNA-DNA hybrid duplexes by hybridization of miR-155 with its complementary DNA and through the subsequent intercalation of appropriate intercalating agents on gold electrodes. In the first method, the electrochemical behavior of methylene blue intercalated to the miRNA-DNA hybrid duplex, formed between miR-155 and its complementary DNA, on the gold electrode was measured. In the second method, the miRNA-DNA hybrid duplex formed between ferrocene-labeled DNA and miR-155 in solution is intercalated to the pyrenes immobilized on the electrode surface. This lead to an electrochemical signal being generated from the oxidized ferrocene accumulated on the electrode surface. For each method, the limit of detections for the detection of miR-155 were determined to be 0.96 and 2.22 pM, respectively. In addition, the developed electrochemical biosensors were effective in the quantitation of miR-155 in serum sample.

Low-temperature thermal transport measurements of oxygen-annealed Yb2Ti2O7

et al. 2020

View full text Add to dashboard Cite

Low temperature thermal conductivity measurements have been conducted on an oxygen annealed single crystal of Yb2Ti2O7 from 60 mK to 50 K and in magnetic fields up to 8 T applied in the [111] crystallographic direction. The temperature dependence of the conductivity in zero field shows a significant peak in thermal conductivity at T ∼ 13 K and a sharp anomaly at Tc ∼ 0.2 K suggesting that the sample's behaviour is representative of the high-purity limit, with low levels of disorder. The magnetic field dependence of the thermal conductivity close to Tc reveals a re-entrant magnetic phase for a field in the [111] direction. With this new information, analysis of the very low magnetic field behaviour of the thermal conductivity suggests the presence of significant fluctuations close to the phase line.
