Abstract We explore the emergence of many-body physics from quantum mechanics via spontaneous symmetry breaking. To this end. we study potentials which are functionals on the space of Hamiltonians enjoying an unstable critical point corresponding to a random quantum mechanical system (the Gaussian unitary ensemble). but also less symmetrical local minima corresponding to interacting s... https://www.balboasurfandsstylers.shop/product-category/womens-hats/
