Laser Controlled Tunneling in a Vertical Optical Lattice [PDF]
Physical Review Letters, 2011 Raman laser pulses are used to induce coherent tunnelling between neighbouring sites of a vertical 1D optical lattice. Such tunneling occurs when the detuning of a probe laser from the atomic transition frequency matches multiples of the Bloch frequency, allowing for a spectroscopic control of the coupling between Wannier Stark (WS) states.

Bilateral Control with Vertical Contracts [PDF]
The RAND Journal of Economics, 2004 When a manufacturer contracts secretly with competing retailers he is subject to opportunism, and linear or non-linear tariffs may not allow the manufacturer to maintain monopoly prices. To analyse the effects of RPM, O'Brien-Shaffer (1992) use a concept of contract equilibrium which concentrates on pairwise deviations thereby questioning the ...

Simulation of the Vertical-Vertical Controled Source Electromagtic Method
, 2021 <div>Modeling of the Vertical-Vertical Controled Source Electromagtic Method (VVCSEM) on COMSOL Multiphysics. The VVCSEM method is, strictly speaking, an MCSEM (Marine Controlled Source ElectroMagnetic) that uses a vertical electric dipole as source, vertically oriented receivers, and time domain acquisition mode.
