Dynamic radiation force of acoustic waves on absorbing spheres
Acoustic Radiation Force Viscoelasticity Scattering
2010/6/30
We present a theoretical study on how dynamic radiation force of acoustic waves actuates on absorbing spheres. We consider the radiation force is generated by the difference-frequency component of a b...
Quantum noise and self-sustained radiation of PT-symmetric systems
Quantum noise self-sustained radiation PT-symmetric systems
2010/3/10
The observation that PT-symmetric Hamiltonians can have real-valued energy levels even if they are non-hermitian has triggered intense activities, with experiments in particular focusing on optical sy...
