DESPI TE TWO DECADES OF IN TENSE RESEARCH , high temperature superconductors still hold many mysteries. Although they share some properties with their well-understood “conventional” low-temperature cousins, in particular the ability to carry current without any resistance, the differences are plentiful. The most obvious difference is the transition temperature TC, below which superconductivity ...

From few to many: observing the formation of a Fermi sea one atom at a time.

Knowing when a physical system has reached sufficient size for its macroscopic properties to be well described by many-body theory is difficult. We investigated the crossover from few- to many-body physics by studying quasi-one-dimensional systems of ultracold atoms consisting of a single impurity interacting with an increasing number of identical fermions. We measured the interaction energy of...

One Loop at a Time

Classic techniques for proving termination require the identification of a measure mapping program states to the elements of a well founded domain and to show that this measure decreases with each iteration of a loop in the program. This is a global termination condition — there is a single measure which must be shown to decrease over all of the loops in the program. In this abstract we look at...

One step at a time

for these devices. But the macro layer of a network can be expanded to go a long way. In the near-term, the smartphone challenge is not about providing the capacity to cope with subscriber datausage, but is related to how the signaling system is configured. To build the networks that will cope with long-term predictions requires a new approach to network construction, heterogeneous networks – m...
