ANISOTROPIC LANDAU-LIFSHITZ MODEL IN DISCRETE SPACE-TIME

Anisotropic Landau-Lifshitz model in discrete space-time

We construct an integrable lattice model of classical interacting spins in discrete space-time, representing a discrete-time analogue of the lattice Landau-Lifshitz ferromagnet with uniaxial anisotropy.As an application we use this explicit discrete symplectic integration scheme Pump to compute the spin Drude weight and diffusion constant as functi

Detection and location of surfaces in a 3D environment through a single transducer and ultrasonic spherical caps

In this paper, an ultrasonic arc map method for flat mapping is extended to three-dimensional space replacing the circumference arcs by spherical caps.An enclosed environment is scanned by employing a single ultrasonic device.The range, position, and orientation of the transducer are Felt Hats used to digitize the uncertainty caps and place them in
