Fundamental Tests of Quantum Mechanics with the Majorana Demonstrator
The Majorana Demonstrator is an ultra-low-background experiment, with a primary physics goal to search for neutrinoless double beta decay of 76Ge.  The Demonstrator consisted of two modules of p-type point-contact (PPC) germanium detectors operating inside a large passive shield on the 4850’ level of the Sanford Underground Research Facility in Lead, SD.  The same design features and data that underpin the neutrinoless double beta decay search – low backgrounds, excellent energy resolution, and sharp pulse characteristics – also enabled a variety of searches for Beyond the Standard Model (BSM) physics.  In this talk, I will present an overview of the Majorana physics program, particularly highlighting the tests of quantum mechanics.  Recently published results investigate the quantum measurement problem, probing models of wave function collapse.  We also search for violation of the Pauli exclusion principle, testing a core tenet of quantum mechanics.
