This geometry, Berry realized, gives quantum particles a kind of memory. At the time, Berry was investigating a very simple system: the quantum state of a particle, such as a neutron, in a ...

Our sensor responses were characterized over a concentration range of 9.8 ppb to 2.88 ppm of un-ionized ammonia. For this, an ammonium chloride stock was used to adjust the total concentrations of ...
