Observing polarization patterns in the collective motion of nanomechanical arrays
Nature Communications, 2022 Coupled nanomechanical resonator arrays serve as model systems to study collective dynamical phenomena. Doster et al. introduce a two-dimensional array of pillar resonators encoding a mechanical polarization degree of freedom for analyzing polarization ...

Entangling Different Degrees of Freedom by Quadrature Squeezing Cylindrically Polarized Modes [PDF]
Physical Review Letters, 2011 Quantum systems such as, for example, photons, atoms, or Bose-Einstein condensates, prepared in complex states where entanglement between distinct degrees of freedom is present, may display several intriguing features. In this Letter we introduce the concept of such complex quantum states for intense beams of light by exploiting the properties of ...

Resonant diffraction gratings with polarization-dependent efficiencies [PDF]
EPJ Web of Conferences, 2020 Subwavelength-structures with different fill factors in the lateral dimensions result in unique phase shifts for the different polarization states of transmitted light. By using this additional degree of freedom for diffractive optical elements, we yield

Integrability of One-Degree-of-Freedom Symplectic Maps with Polar Singularities [PDF]
Journal of the Physical Society of Japan, 2006 In this paper, we treat symplectic difference equations with one degree of freedom. For such cases, we resolve the relation between that the dynamics on the two dimensional phase space is reduced to on one dimensional level sets by a conserved quantity and that the dynamics is integrable, under some assumptions.
