Nonlinear behavior of geometric phases induced by photon pairs [PDF]
, 2011 In this study, we observe the nonlinear behavior of the two-photon geometric phase for polarization states using time-correlated photons pairs. This phase manifests as a shift of two-photon interference fringes.

Single-shot Fresnel incoherent digital holography based on geometric phase lens [PDF]
Journal of Modern Optics, 2018 Single-shot and incoherent imaging are two important properties of digital holography that can extend its application range. In this study, a simple, compact, in-line Fresnel incoherent digital holographic recording system is proposed that is capable of ...

Geometric phase in dephasing systems
, 2005 Beyond the quantum Markov approximation, we calculate the geometric phase of a two-level system driven by a quantized magnetic field subject to phase dephasing.

Tunable High-Resolution Macroscopic Self-Engineered Geometric Phase Optical Elements. [PDF]
Physical Review Letters, 2018 Artificially engineered geometric phase optical elements may have tunable photonic functionalities owing to their sensitivity to external fields, as is the case for liquid crystal based devices.

Geometric phase at graphene edge
, 2014 We study the scattering phase shift of Dirac fermions at graphene edge. We find that when a plane wave of a Dirac fermion is reflected at an edge of graphene, its reflection phase is shifted by the geometric phase resulting from the change of the ...

Observation of the geometric phase effect in the H + HD → H2 + D reaction
Science, 2018 Pinpointing the role of geometric phase During chemical reactions, electrons usually rearrange more quickly than nuclei. Thus, theorists often adopt an adiabatic framework that considers vibrational and rotational dynamics within single electronic states.

Quantitative two-dimensional strain mapping of small core–shell FePt@Fe3O4 nanoparticles
New Journal of Physics, 2016 We report a facile one-pot chemical synthesis of colloidal FePt@Fe _3 O _4 core–shell nanoparticles (NPs) with an average diameter of 8.7 ± 0.4 nm and determine their compositional morphology, microstructure, two-dimensional strain, and magnetic ...

Quantum Reports, 2020 We investigate the dynamics of a particle in a confined periodic system—a time-dependent oscillator confined by infinitely high and moving walls—and focus on the evolution of the phase of the wavefunction.

Observation of nonlinear variations in three-vertex geometric phase in two-photon polarization qutrit [PDF]
, 2015 We experimentally observed nonlinear variations in the three-vertex geometric phase in a two- photon polarization qutrit. The three-vertex geometric phase is defined by three quantum states, which generally forms a three-state (qutrit) system.

All-dielectric planar chiral metasurface with gradient geometric phase.
Optics Express, 2018 Planar optical chirality of a metasurface measures its differential response between left and right circularly polarized (CP) lights and governs the asymmetric transmission of CP lights.
