Geometric Mixing, Peristalsis, and the Geometric Phase of the Stomach. [PDF]
PLoS ONE, 2015 Mixing fluid in a container at low Reynolds number--in an inertialess environment--is not a trivial task. Reciprocating motions merely lead to cycles of mixing and unmixing, so continuous rotation, as used in many technological applications, would appear

Wave description of geometric phase [PDF]
Journal of the Optical Society of America A, 2023 Since Pancharatnam’s 1956 discovery of optical geometric phase and Berry’s 1984 discovery of geometric phase in quantum systems, researchers analyzing geometric phase have focused almost exclusively on algebraic approaches using the Jones calculus, or on spherical trigonometry approaches using the Poincaré sphere.

Acoustic geometric-phase meta-array [PDF]
New Journal of Physics, 2021 Metasurfaces based on geometric phase acquired from the conversion of the optical spin states provide a robust control over the wavefront of light, and have been widely employed for construction of various types of functional metasurface devices. However,

Geometric Phase in Open Systems [PDF]
Physical Review Letters, 2003 We calculate the geometric phase associated to the evolution of a system subjected to decoherence through a quantum-jump approach. The method is general and can be applied to many different physical systems. As examples, two main source of decoherence are considered: dephasing and spontaneous decay.

Electric-magnetic geometric phase
Physical Review ResearchGeometric phases play an enormous role in optics and are generally associated with the evolution of light's polarization state on the Poincaré sphere, or its spin on the sphere of spin directions.

Geometric phase for twisted light
Optics Express, 2023 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.

Gravity and geometric phases [PDF]
Physical Review D, 1995 The behavior of a quantum test particle satisfying the Klein-Gordon equation in a certain class of 4 dimensional stationary space-times is examined. In a space-time of a spinning cosmic string, the wave function of a particle in a box is shown to acquire a geometric phase when the box is transported around a closed path surrounding the string.
