Consider an undamped single degree-of-freedom system experiencing harmonic excitation whose equation of motion (EOM) is given by: Here omega n is known as the natural frequency of response. The ...

Researchers are exploring multi-level atomic interactions to enhance quantum entanglement. Using metastable states in strontium, they demonstrate how photon exchange can sustain correlations, offering ...

Shown below left is the original single-DOF system with base excitation that is experiencing near-resonant response. On the right is the same system with an absorber mass (in green) attached to the ...
