Abstract The Kitaev honeycomb model has received significant attention for its exactly solvable quantum spin liquid ground states and fractionalized excitations. For realizing the model, layered cobalt oxides have been considered a promising platform. Yet, in contrast to conventional wisdom about single- q zigzag magnetic order inferred from previous studies of Na 2 IrO 3 α RuCl candidate materials, recent experiments on two representative oxides, hexagonal Co TeO 6 monoclinic SbO ,...
Fluorescence resonance energy transfer (FRET) by acceptor photobleaching is a simple but effective tool for measurements of protein-protein interactions. Until recently, it has been restricted to qualitative or relative assessments owing the spectral bleed-through contamination resulting from fluorescence overlap between donor and acceptor. In this paper, we report quantitative algorithm that combines unmixing technique with FRET photobleaching. By spectrally emissions before after...
This article describes a wide-field time-domain fluorescence lifetime imaging (FLIM) microscope with optical sectioning. The FLIM system utilizes time-gated image intensifier, minimum gate width of 85 ps, to achieve high temporal resolution decays induced by ultrashort laser pulses. Different configurations, using excitation pulses picojoule energy at 80 MHz repetition rate and nanojoule 10 kHz, are compared. instrument has dynamic range spanning from 100 ps tens μs is shown have...
Whole-field photorefractive holography can be combined with low-coherence interferometry for three-dimensional imaging and other applications, including through turbid media, but the off-axis holographic recording geometry results in a limited field of view when light low temporal coherence is used. We show that tilting energy fronts respect to wave by use prisms eliminate this problem point out approach will useful many linear nonlinear wave-mixing experiments.

We present the first multilayer, foldable chipless RFID tag design that works in high frequency (HF) range.

Na$_3$Co$_2$SbO$_6$ is a potential Kitaev magnet with monoclinic layered crystal structure. Recent investigations of the $C_3$-symmetric sister compound Na$_2$Co$_2$TeO$_6$ have uncovered unique triple-$\mathbf{q}$ magnetic ground state, as opposed to single-$\mathbf{q}$ (zigzag) one, prompting us examine influence reduced structural symmetry on its state. Neutron diffraction data obtained twin-free reveal that state remains multi-$\mathbf{q}$ despite system's strong in-plane anisotropy....
