... magnetic field is the circulating current, we see that these two classical states have opposite circulating currents. However, quantum mechanically, the charging energy couples these two states and results in an energy level repulsion at Φext = 0.5 Φ0, so that there the system is in a linear superpo ...

Nowadays manufacturing technologies can be expected to get close to realizing such symmetries - perhaps not ...

The Fermi-Hubbard model 11 The Hubbard model
... can do second-order perturbation theory on Eq. (11.3) for small J/|U | and obtain an e↵ective model where there are only on-site dimers which hop from one site to the neighbouring one with the hopping energy of approximately J 2 /|U |. Therefore, the hopping goes to zero as |U | ! 1; in e↵ect, the d ...

Yang-Baxter sigma models based on the CYBE
... It is known that Yang-Baxter sigma models provide a systematic way to study integrable deformations of both principal chiral models and symmetric coset sigma models. In the original proposal and its subsequent development, the deformations have been characterized by classical r-matrices satisfying t ...

Lower bounds for quantum communication complexity
... In a quantum protocol (as defined by Yao [41]) two players Alice and Bob each receive an input, and have to compute some function defined on the pair of inputs cooperatively. To this end they exchange messages consisting of qubits, until the result can be produced from some measurement done by one o ...

Three Myths about Time Reversal in Quantum Theory

In place of the myths, I will ...

Theory of fluctuations in a network of parallel superconducting wires
... There has been considerable recent interest in thin wires that undergo transitions into an ordered state, such as superconducting or ferromagnetic. For example, experiments have suggested that single-walled carbon nanotubes (which have diameters of only about 4 Å) are superconducting with a transiti ...
