Problem Set 8 Solution
... (b) (4 points) Since the momentum eigenstates are the same as the energy eigenstates for a free particle, Equation 3c can also be viewed as a superposition of momentum eigenstates. Using pk = nkk, we can therefore say that the possible outcomes of a measurement of momentum are pk = (3n, 5n, n)/L an ...

... and the magnetic quantum number of the atom’s hyperfine state. In order to transfer the magnetically trapped atoms into the optical lattice potential, we slowly increase the intensity of the lattice laser beams over a time of 80 ms so that a lattice potential depth VA of up to 11 recoil energies E r ...

Proof that Casimir force does not originate from vacuum energy
... the condensed-matter community, is that Casimir force has the same physical origin as van der Waals force [8–14], which does not depend on energy of the vacuum. From a practical perspective, the two points of view appear as two complementary approaches, each with its advantages and disadvantages. Fr ...

The (strong) KS theorem is usually proved by taking a finite subset of interconnected (the dimension of the vector space must be three or higher for interconnectivity) contexts (or any similar encoding thereof, such as maximal observables, orthogonal bases, or unitary operators), and by demonstratin ...

Topological Quantum Computation from non-abelian anyons
... This is non-trivial even for abelian anyons. Say we have two identical particles which pick up a phase eiα when exchanged, or equivalently, e2iα under a 2π rotation of one around the other. Then a pair of these picks a phase e8iα when exchanged with different pair. ...
