A01.00001: Laser Radar, Environmental Optics and Undergraduate Research Nimmi Sharma At Central Connecticut State University (CCSU) we have developed a vibrant research program in laser radar and environmental optics which actively involves undergraduates. Laser radar (also known as LIDAR) is a technique in which laser light is scattered off a target and the scattered return is analyzed to derive distance to the target and target properties. In the CCSU Laser Atmospheric Studies and Environmental Research (LASER) group, we design and develop LIDAR systems, use LIDAR to transmit visible laser light into the atmosphere to investigate atmospheric aerosols (suspended particulates which impact climate and air quality), conduct multi-instrument studies to increase our understanding of local, regional and global atmospheric characteristics, pollution and dynamics, and develop collaborations with national and international partners. The group is centered on involving undergraduates in research and builds students' skills in an environment that stresses both teamwork and independent initiative. This paper describes projects in the research group and the processes that have been found to be successful in building and sustaining an undergraduate research group. [Preview Abstract] |

A01.00002: Drawing Quantum Mechanics Douglas Sweetser Causality is different between classical and quantum mechanics. Why? The worldline of a classical particle is a record of time and 3D location in space-time. Each event has a time-like relation to the last event. In quantum mechanics, the location of the observer in space is known: 0, 0, 0. The worldline of an observer must be identical to the time axis, forever staying at the spatial origin. The wave function by contrast has more freedom to wander through space-time. In classical quantum mechanics, it is reasonable to constrain the wave function events to sets that have time-like separations as happens in classical mechanics. The conjugate of the wave function will be a reflection across the time axis, switching the signs of each of the three spatial components. Each event of the conjugate is space-like separated from the wave function proper, no exceptions. A conjugate is a mirror reflection augmented by a 180 degree rotation. A reflection in a mirror is both exquisitely precise yet unreachable. Every calculation in quantum mechanics pairs information with its space-like reflection. This is the reason quantum mechanics is nonlocal. The t-shirt \textit{may} be done in time... [Preview Abstract] |

A01.00003: Untangling entanglement in quantum computers and a request for help Jeffrey Boyd Comments made after an earlier version of this presentation (at the APS-NE meeting at Suffolk University a year ago) have become the central theme. The authors of a neutron interferometer experiment published in Physical Review in 1995 said that neither they, nor quantum mechanics could not explain their data. We propose a paradigm shift: that waves and neutron particles travel in opposite directions. There are two symmetrical ways of understanding Nature, with drastically different assumptions BUT THE SAME MATHEMATICS. The alternative view of Nature is called the Theory of Elementary Waves (TEW). When this paradigm shift was presented to APS-NE in 2018, someone in the audience said that from the viewpoint of quantum computation there is no difference between QM and TEW. This is the most helpful comment ever. Just as QM and TEW share identical mathematics, also they share the same quantum computer science, as we will show, using an IBM quantum computer in the cloud. As an outsider I again request help from the APS-NE. I need help in bringing an intriguing idea to a wider audience of physicists. I am NOT asking you to endorse this wild idea, rather that you be available to serve as a reviewer. [Preview Abstract] |
