From it's birth, quantum mechanics has conflicted with our classical intuition of the world. The Schrodinger Cat parable depicts this conflict with an image of a cat in a superposition state of being both dead and alive. In our description of the microscopic world, we can move past this conflict, accepting that the microscopic world is fundamentally different. The question is then: can this sort of superposition phenomenon appear in the macroscopic world? In my talk, I will discuss our proposal for a Macroscopic superposition state in ultra cold atomic gasses. Our proposed system involves a bubble of one type of Bose gasses immersed in another. The "Cat" state is a super-positioned of the bubble in two separate potential wells at the same time. I will argue why this state is more robust than previous proposals and outline our mixed analytic and numerical approach to proving this. I will conclude with a brief discussion on the effects of finite temperature fluctuation and decoherence. This talk is a part of the student seminar series. Multiple ten minute talks starting at 2:00pm
