WebApr 6, 2024 · Firstly, they mixed a low concentration solution of HPC in water with oil to form an emulsion in which tiny droplets of aqueous HPC form. The water from these droplets was then removed by heating the emulsion to 68.5–77.5 °C, producing visibly red, green, and blue microparticles of pure HPC. The final color of the HPC liquid crystal phase is ... WebApr 9, 2024 · Abstract and Figures.

WebHowever, it is shown here that in superlattices without disorder a spectral phase transition can be observed as well, which does not correspond to a non-Hermitian delocalization phase transition. The predicted phenomena could be observed in non-Hermitian photonic quantum walks, where synthetic superlattices with controllable M and imaginary ... WebJan 15, 2024 · However, for μ / 2 t = 1 it presents a topological quantum phase transition between two superconducting phases with radically different physical (topological) properties [4], [5], [6]. The phase for μ / 2 t < 1 is topologically non-trivial and the main feature of this phase is the presence of fermionic modes, called Majoranas, at the ends of ... WebJul 22, 2024 · Statistical spin dynamics plays a key role in understanding the working principle for novel optical Ising machines. Here, we propose the gauge transformation for a spatial photonic Ising machine, where a single spatial phase modulator simultaneously encodes spin configurations and programs interaction strengths.
