New recursion relations for tree amplitudes of gluons
, 2004
"... We present new recursion relations for tree amplitudes in gauge theory that give very compact formulas. Our relations give any tree amplitude as a sum over terms constructed from products of two amplitudes of fewer particles multiplied by a Feynman propagator. The two amplitudes in each term are phy ..."

are physical, in the sense that all particles are onshell and momentum conservation is preserved. This is striking, since is it just like adding certain factorization limits of the original amplitude to build up the full answer. As examples, we recompute all known treelevel amplitudes of up to seven gluons
Entanglement of Formation of an Arbitrary State of Two Qubits
, 1998
"... The entanglement of a pure state of a pair of quantum systems is defined as the entropy of either member of the pair. The entanglement of formation of a mixed state ρ is defined as the minimum average entanglement of a set of pure states constituting a decomposition of ρ. An earlier paper [Phys. Rev ..."

particle has a definite spin direction. A mixed state is entangled if it cannot be represented as a mixture of factorizable pure states. In the last couple of years a good deal of work has been devoted to finding physically motivated measures of entanglement, particularly for mixed states of a bipartite
DBranes on CalabiYau Spaces and Their Mirrors
, 1996
"... We study the boundary states of Dbranes wrapped around supersymmetric cycles in a general CalabiYau manifold. In particular, we show how the geometric data on the cycles are encoded in the boundary states. As an application, we analyze how the mirror symmetry transforms Dbranes, and we verify tha ..."

In the presence of a Dbrane, the boundary conditions for open
Quantum electrodynamics of strong fields
, 1977
"... Quantum electrodynamics of strong external fields is investigated in the context of atomic physics. If the electromagnetic coupling constant Za becomes sufficiently large ( Z> l / a % 137 for point sources or Z> 172 for extended nuclei) bound electron states can join the negativeenergy conti ..."

Multiple particle interference and quantum error correction
"... The concept of multiple particle interference is discussed, using insights provided by the classical theory of error correcting codes. This leads to a discussion of error correction in a quantum communication channel or a quantum computer. Methods of error correction in the quantum regime are presen ..."

Quantum Field Theory of ManyBody Systems
, 2004
"... condensation Extended objects, such as strings and membranes, have been studied for many years in the context of statistical physics. In these systems, quantum effects are typically negligible, and the extended objects can be treated classically. Yet it is natural to wonder how strings and membrane ..."

The MODIS cloud products: Algorithms and examples from Terra
 IEEE Transactions on Geoscience and Remote Sensing
, 2003
"... (MODIS) is one of five instruments aboard the Terra Earth Observing System (EOS) platform launched in December 1999. After achieving final orbit, MODIS began earth observations in late February 2000 and has been acquiring data since that time. The instrument is also being flown on the Aqua spacecraf ..."
