• Title: Geometric phase for twisted light
• Authors: Li-Ping Yang
• Abstract summary: Polarization vectors of light traveling in a coiled optical fiber rotate around its propagating axis even in the absence of birefringence. We show that similar geometric rotations also exist for twisted light carrying orbital angular momentum (OAM) The corresponding geometric phase can be applied in photonic OAM-state-based quantum computation and quantum sensing.

• Abstract: Polarization vectors of light traveling in a coiled optical fiber rotate around its propagating axis even in the absence of birefringence. This rotation was usually explained due to the Pancharatnam-Berry phase of spin-1 photons. Here, we use a purely geometric method to understand this rotation. We show that similar geometric rotations also exist for twisted light carrying orbital angular momentum (OAM). The corresponding geometric phase can be applied in photonic OAM-state-based quantum computation and quantum sensing.

  We present a field-theoretical model of spin-orbit interaction and photonic spin/orbit Hall effects. Our approach reformulates light propagation along helical paths as solving the Maxwell equations in a ray-based curvilinear coordinate system. We find that the transverse spin of evanescent waves couples with EOAM, revealing that the geometric phase of elliptically polarized light differs from that of circularly polarized light.

We sort the same atomic sample into multiple geometries with success probabilities exceeding 99 % per imaging and rearrangement cycle.

By applying a standard quantum field theory using a coherent state, we obtained the gauge-independent expressions of spin and orbital angular momentum operators.

• Polarimetric Spatio-Temporal Light Transport Probing [33.499684969102816]
  Light can undergo complex interactions with multiple scene surfaces of different material types before being reflected towards a detector. During this transport, every surface reflection and propagation is encoded in the properties of the photons that ultimately reach the detector. Existing methods can untangle these into their spatial and temporal dimensions, fueling geometric scene understanding. We propose a computational light-transport imaging method that captures the spatially- and temporally-resolved polarimetric response of a scene.

  The propagation of a neutrino beam is described by a density matrix evolving in a state space with non-trivial geometry. We show that, in the case of two flavor neutrino oscillations, the geometric phase is independent of the Majorana phase and it can be used as a measure of coherence of the neutrino beam.

  We suggest the measurement of the twist of a chiral mechanical element induced by a gravitational wave. The induced twist rotates a flat optical mirror on top of this chiral element, leading to the deflection of an incident laser beam. We estimate a gravitational wave strain sensitivity between 10-21/sqrtHz and 10-23/sqrtHz at around 10 kHz frequency.

  Entanglement in high-dimensional quantum systems, where one or more degrees of freedom of light are involved, offers increased information capacities and enables new quantum protocols. Here, we demonstrate a functional source of high-dimensional, noise-resilient hyperentangled states encoded in time-frequency and vector-vortex structured modes. We generate highly entangled photon pairs at telecom wavelength that we characterise via two-photon interference and quantum state tomography, achieving near-unity visibilities and fidelities.

  We show that the winding number of the Hamiltonian eigenstates can be read-out by measuring the mean chiral displacement of a single-particle wavefunction. This implies that the mean chiral displacement can detect the winding number even when the underlying Hamiltonian is quenched between different topological phases.
