BFKL approach and six-particle MHV amplitude in N=4 super Yang-Mills
BFKL approach six-particle MHV amplitude N=4 super
2010/11/30
We consider the planar MHV amplitude in N=4 supersymmetric Yang-Mills theory for 2 -> 4 particle scattering at two and three loops in the Regge kinematics. We perform an analytic continuation of two-...
Open Quantum System Dynamics from a Measurement Perspective: Applications to Coherent Particle Transport and to Quantum~Brownian Motion
Open Quantum System Dynamics a Measurement Perspective Applications Coherent Particle Transport Quantum~Brownian Motion
2010/3/19
We employ the theoretical framework of positive operator valued measures, to study Markovian open quantum systems. In particular, we discuss how a quantum system in uences its environment, or parts th...
Classical Particle in Presence of Magnetic Field, Hyperbolic Lobachevsky and Spherical Riemann Models
Magnetic Field Spherical Riemann Models Hyperbolic Lobachevsky
2010/1/10
Motion of a classical particle in 3-dimensional Lobachevsky and Riemann spaces is studied in the presence of an external magnetic field which is analogous to a constant uniform magnetic field in Eucli...
