Product Vacua with Boundary States
... The fact that one of each of the n types of particles can appear in a ground state of the system, i.e., without raising the energy, should not be interpreted as implying that the particles are massless. Quite to the contrary, there is a mass gap for each of them. It turns out, however, that they can ...

... How can one diagonalize the Hamiltonian? Using a computer is not practical for large values of N. Indeed, H is a 2N × 2N matrix. Moreover, direct numerical diagonalization will give all eigenstates, while often one is interested in only low-lying states. A very elegant alternative approach which ove ...

Bose-Einstein spin condensates: revisiting the Einstein
... • When a system of bosons undergoes the superfluid transition (BEC), spontaneous symmetry breaking takes place; the order parameter takes a non-zero value. This
introduces a (complex) classical field with a phase.
Similar to ferromagnetic transition.
• Powerful idea: explains superfluid currents ...

Quantum Electronics
... Entanglement gets right into the least understood aspect of Quantum Theory, but it can be briefly described as being the idea that two particles are linked by nature so that when one is affected, the other is as well. The distance between the two particles makes no difference and they are always in ...

Introduction To Quantum Computing
... Our entire discussion so far has been on “perfect” quantum gates, but of course they are not perfect. Various “threshold theorems” have suggested that we need 10^4 to 10^6 gates in less than the decoherence time in order to apply quantum error correction (QEC). QEC is a big enough topic to warrant s ...
