Laser Controlled Tunneling in a Vertical Optical Lattice
Laser Controlled Tunneling in a Vertical Optical Lattice
Raman laser pulses are used to induce coherent tunneling between neighboring 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) …
