Abstract In this paper we present a torsional non-relativi-stic Chern–Simons (super)gravity theory in three spacetime dimensions. We start by developing the non-relativistic limit of purely bosonic relativistic teleparallel formulation gravity. On-shell latter yields non-Riemannian setup with non-vanishing torsion, which, at level, translates into spatial torsion sourced cosmological constant. ...

We study an anisotropic two-dimensional non-Hermitian Lieb lattice, where the staggered gain and loss present in horizontal vertical directions, respectively. The intra-cell nonreciprocal coupling generates magnetic flux enclosed unit cell of lattice creates nontrivial topology. active dissipative topological edge states are along also supports passive corner state. At appropriate flux, non-Her...

Abstract Some quantum optics researchers might not realize that classical electromagnetism predicts a $$\mathbf {\pi }$$ π phase shift between S- and P-polarized reflection think the coefficients of transverse modes are independent, or such has no measurable consequences. In this paper, we discuss theoretical...
