A simple noninterferometric approach for probing the geometric phase of a structured
Gaussian beam is proposed. Both the Gouy and Pancharatnam-Berry phases can be …

We derive and experimentally investigate a strong uncertainty relation valid for any n unitary
operators, which implies the standard uncertainty relation and others as special cases, and …

The Doppler frequency shift of sound or electromagnetic waves has been widely
investigated in many different contexts and, nowadays, represents a formidable tool in …

Unitary evolutions of a qubit are traditionally represented geometrically as rotations of the
Bloch sphere, but the composition of such evolutions is handled algebraically through matrix …

We propose a new method for determining the Mueller matrix of an arbitrary optical element
and verify it with three known optical elements. This method makes use of two universal SU …

We demonstrate an innovative technique based on the Pancharatnam–Berry phase that can
be used to determine whether an optical system characterized by a Jones matrix is …

Holonomic phases—geometric and topological—have long been an intriguing aspect of
physics. They are ubiquitous, ranging from observations in particle physics to applications in …

In 1984 Berry addressed a quantum system undergoing a unitary and cyclic evolution under
the action of a time-dependent Hamiltonian (MV Berry, 1984). The process was supposed to …

We present a method to measure the geometric phase defined for three internal states of a
photon (polarizations) using a three-pinhole interferometer. From the interferogram, we can …

This paper describes polarimetric strategies based on measuring the light's geometric
phase, which results from the evolution of the polarisation state while traversing an optical …
