DOI: 10.1080/09500340.2025.2478489
Abstract: In this paper, we optimized a multi-belt filter with ternary phase amplitude. Single and dual channel longitudinal magnetization needles were obtained by tight focusing azimuthally polarized sinh-Gaussian beam using by the multi-belt filter and spiral… read more here.

DOI: 10.1088/1742-5468/ab609a
Abstract: We show that the symmetry-breaking gap of the quantum Ising model in the transverse field can be extracted from free evolution of the longitudinal magnetization taking place after a gradual quench of the magnetic field.… read more here.
