The Death of Moores Law and the Future of Computing

For decades, society has witness the stunning progress of computing technologys power and reach. Computers and their applications are pervasive in daily life as well as in physics research. In 1965 Intel co-founder Gordon Moore predicted that computing power would (roughly) double every 18th months, and indeed ever since the inception of the semiconductor-based transistor and the microprocessor, computing power has grown exponentially every year. But as transistor components approach the atomic scale, new obstacles in IC design have slowed this rate of growth. Other limitations to the current style of processing units (related to power consumption, physical space, design, and manufacturing) are responsible for a slowing down of Moores Law, and the search is on for ways to restore the growth of computing power to its historic rate. In this talk, these limitations on current traditional microprocessors will be reviewed, and several alternative technologies and workarounds (such as quantum and parallel computing) will be introduced, along with their own limitations.

Solvable Relativistic Hydrogenlike System in Supersymmetric Yang-Mills Theory

Both the classical Kelper problem and its quantum mechanical version, the hydrogen atom, enjoy a hidden symmetry, the conservation of the Laplace-Runge-Lenz vector, which makes these problems superintegrable. We wonder if there is a relativistic quantum field theory extension that preserves this symmetry. The answer is positive. In this presentation, we will review the paper by Simon Caron-Huot et.al, that identifies the dual conformal symmetry of planar N=4 super Yang-Mills theory with the well known symmetries of the hydrogen atom. Also, it points that the dual conformal symmetry offers a novel way to compute the spectrum of bound states of massive W bosons in the theory.
