Diffraction of matter waves is a fundamental consequence of quantum mechanics, directly illustrating the core principles of wave-particle duality, quantum superposition, and quantum interference. De ...
Sum-frequency generation (SFG) is a powerful vibrational spectroscopy that can selectively probe molecular structures at surfaces and interfaces, but its spatial resolution has been limited to the ...
Orbital angular momentum, as an important spatial degree of freedom of light, has prompted various promising applications. The recently proposed generalized vortex beams may further enhance the ...
