Transmission-type photonic doping for high-efficiency epsilon-near-zero supercoupling
General concept We begin the discussion with the general ENZ supercoupling model, which consists of an arbitrary-shaped ENZ channel with the area Ap connecting two rectangular waveguide ports with the widths of a1 and a27,8. The EM waves are excited from Port 1, squeezed through the ENZ channel, and received at Port 2. As demonstrated…

Cancer characterization using light backscattering spectroscopy and quantitative ultrasound: an ex vivo study on sarcoma subtypes
Animal models In this study, the use of chondrosarcoma and osteosarcoma tumors is motivated by their different microstructures. Characterizing these tumors appears as a way to validate our bimodal method with the aim of establishing a proof-of-concept. Given that the inner mechanisms of our methods probe the tissue microstructure, our approach could potentially be applied to other…

Realization of an inherent time crystal in a dissipative many-body system
Theoretical model We investigate a system consisting of a collection of four-level atoms that are driven by a continuous-wave (CW) laser, as depicted in Fig. 1a, b. There are a pair of Kramers doublets for both the optical ground and excited states. The atoms possess electron spins and interact with one another via magnetic dipole-dipole interactions.…

Versatile bubble maneuvering on photopyroelectric slippery surfaces
Bubble transport on the PESS The PESS is constructed with a sandwich structure including a slippery layer, a pyroelectric layer and a photothermal layer from top to bottom (Fig. 1a and Supplementary Fig. 1). Briefly, the mixture of Fe3O4 nanoparticles and polydimethylsiloxane (PDMS) was streamed on a commercial lithium niobate wafer acting as the pyroelectric layer, and…

Extremal quantum correlation generation using a hybrid channel
In this section, we give the details of the obtained results for the generation and dynamics of quantum discord, non-classical correlations, entanglement, and entropy using TDD, CN, LQU, and LE measures given in Eqs. (17), (18), (21) and (23). The results are based on the final density matrix’s elements given in Eq. (13) when the…

Strain-controlled spin transport in a two-dimensional (2D) nanomagnet
Formation energy An evaluation of the energetically advantageous configuration of monolayer CrOBr under strain conditions is determined by the formation energy E\(_{form}\), defined as follows: $$\begin{aligned} E_{form}= \frac{(E_{T} – n_{1}E_{Cr} – n_{2}E_{O} – n_{3}E_{Br})}{n_{1} + n_{2} + n_{3}} \end{aligned}$$ (6) where, E\(_{T}\) represents the total energy of the strained CrOBr, and E\(_{Cr}\), E\(_{O}\), E\(_{Br}\) are…
