NLTE phenomena are far more complex than LTE. In LTE, the rates controlling the absorption and emission of radiation are a unique function of Te, density, and composition. In NLTE, the analogous rates depend not only on Te, and the material composition, but also crucially on the full electron and photon distribution functions.

While analysis of general NTLE behaviors remains difficult, the practical case of quasi-steady-state NLTE systems is amenable to simplification. We have developed a general theory and computational framework to treat atomic radiation responses to non-Planckian or hot electron perturbations. Atomic radiation in the neighborhood of equilibrium is described by a linear response matrix giving the net emission (absorption) at a given frequency caused by deviations from the black-body radiation spectrum at a second frequency. The response matrix is calculated by solving the usual kinetic rate equations with special boundary conditions. According to Onsager, the matrix must be symmetric, yielding a powerful test for NLTE codes. We prove that the principle of minimum entropy production characterizes steady-state near-LTE excited-state populations and derive the exact response matrix in terms of the underlying kinetics. Applications include the "factorization" of the equations of NLTE radiative transfer resulting in large increases in computational efficiency, and the "automated" discovery of tailored x-ray (including x-ray laser) schemes.

Protein folding is an example of a phase transition in which rigidity percolates as the protein proceeds from a floppy to a rigid state. We show how the folding pathway can be determined from the three- dimensional native state structure of the protein.

In designing new drugs in the pharmaceutical industry, it is important to take account of the flexibility of both the target protein and the ligand (drug) that is to be attached. We will show a movie of the motion of a protein-ligand complex.

I will discuss some theoretical ideas and experiments in semiconductor systems, and in particular some novel approaches with optical microcavities that make use of the decay of excitons into photons. In this case, the exciton condensate is a special kind of laser.

We will describe a set of experiments that involve the utilization of micro-cantilevers as force sensors to measure gravity-like forces at length scales between 15 and 100 microns [1]. In all schemes an alternating mass scheme is designed to excite a test mass which is placed on a sensitive cantilever with force resolution exceeding 10$^{-18}$ N. We will discuss the current limits of our experiments and their future extensions.
