Cooling in strongly correlated optical lattices: prospects and challenges (2010, methodology): “Although laser intensities can be high in a lattice, it is unlikely that photoionization will have a detrimental effect for short wavelength lattices, since the laser wavelength can be tuned away from exciting intermediate electronic states [99, 100].”
Measuring multipartite entanglement through dynamic susceptibilities (2015, methodology): “Dynamic susceptibilities are routinely measured in manybody systems using well-established techniques such as Bragg spectroscopy [28, 29] or neutron scattering [30].”
Topological semimetal in a fermionic optical lattice (2010, methodology): “For example, the energy-band structure of the unique band-crossing degeneracy point can be detected directly using experimental techniques such as Bragg scatterin”
At the limits of criticality-based quantum metrology: apparent super-Heisenberg scaling revisited (2017, background): “[28]), which is measurable, for instance, by means of Bragg spectroscopy [29,30].”
