The slow zero order antisymmetric Lamb mode in phononic crystal plates.
In this paper, the group velocities of the zero order antisymmetric (A0) Lamb modes in a phononic crystal plate with single layer cylindrical holes parallel to the surface of the plate were investigated theoretically. The results show that by increasing the filling fraction, the A0 mode can be efficiently slowed down and the group velocity of the A0 modes can be tuned from the positive to the n...

متن کاملSquare lattice photonic crystal point-shifted nanocavity with lowest-order whispering-gallery mode.
We propose a point-shifted nanocavity based on square lattice photonic crystal, which sustains a lowest-order whispering-gallery (WG) mode. In simulation, the optimized WG mode (quality (Q) factor approximately 14,000) in point-shifted nanocavity can be with smaller mode volume (approximately 5.5(lambda/2n)(3)) but larger nano-post tolerance than those in single-defect cavity design. From well-...
متن کاملAn investigation of the lowest-order transverse-electric „TE1... mode of the parallel-plate waveguide for THz pulse propagation
We experimentally and theoretically investigate the lowest-order transverse-electric TE1 mode of the parallel-plate waveguide (PPWG) for the propagation of broadband THz pulses. We demonstrate undistorted THz pulse propagation via the single TE1 mode, solving the group-velocity-dispersion and spectral-filtering problems caused by the mode’s low-frequency cutoff. We observe a remarkable counteri...
متن کاملObservation of the Phononic Lamb Shift in a Synthetic Vacuum
This thesis reports on the implementation of the Fröhlich Hamiltonian in an ultracold atomic mixture. To this end, impurity atoms are immersed into a macroscopic Bose-Einstein condensate (BEC). The impurities are tightly trapped in one direction by a species-selective optical potential. In this scenario their coupling to the excitations (phonons) of the BEC causes energy shifts of their externa...
