Dynamics of cold Fermi atoms in one
... The main difficulties in dealing with such problems are due to the complexity of real objects such as solid materials – natural systems of interest, with a huge number of constituents. First-principle calculations do not allow one to find an analytical solution even to the general three-body Coulomb ...

... If you squeeze together several turns of the coiled-spring toy and then suddenly release them, pulses of closely-spaced turns will move away in both directions. This is called a longitudinal wave. The disturbance is in the same direction as, or parallel to, the direction of the wave’s motion. Sound ...

Let D be an open region in IE and W be any vector space or an Euclidean space. A function f : D → W is said to be differentiable at x ∈ ...

Density of states
.svg?width=300)
In solid-state and condensed matter physics, the density of states (DOS) of a system describes the number of states per interval of energy at each energy level that are available to be occupied. Unlike isolated systems, like atoms or molecules in gas phase, the density distributions are not discrete like a spectral density but continuous. A high DOS at a specific energy level means that there are many states available for occupation. A DOS of zero means that no states can be occupied at that energy level. In general a DOS is an average over the space and time domains occupied by the system. Localvariations, most often due to distortions of the original system, are often called local density of states (LDOS). If the DOS of an undisturbedsystem is zero, the LDOS can locally be non-zero due to the presence of a local potential.
