Observation of Hybrid Soliton Vortex-Ring Structures in Bose-Einstein Condensates

We present the experimental discovery of compound structures comprising solitons and vortex rings in Bose-Einstein condensates (BECs). We examine both their creation via soliton-vortex collisions and their subsequent development, which is largely governed by the dynamics of interacting vortex rings. A theoretical model in three-dimensional (3D) cylindrical symmetry is also presented.Comment: 5 pages, 4 figures; submitted to PR

Ultrahigh reflection from a medium with ultraslow group velocity

We show that an incident wavepacket at the boundary to a medium with extremely slow group velocity, experiences enhanced reflection and a substantial spatial and temporal distortion of the transmitted wave packet. In the limit of vanishing group velocity, light cannot be transferred into the medium due to its perfect reflectivity.Comment: 3 pages, 3 figure

Did Padre Damaso Rape Pia Alba? Reticence, Revelation, and Revolution in José Rizal’s Novels

Thisarticle revisits the debate in 2010 among Philippine Daily Inquirer columnists over the question of whether or not, in José Rizal’s novel Noli me tángere, Padre Damaso “raped” Maria Clara’s mother, Pia Alba, a debate inspired by the Reproductive Health (RH) Bill. Thearticle examines how Rizal employs rhetorical strategies of reticence and revelation along with literary onomastics and allusions in his two novels to create meanings and associations that open his novels to multiple, even competing, interpretations. Such ambiguity reveals the artistic, intellectual, and political stakes of interpretation, which involves not only the struggle for understanding and struggle over meaning, but also the struggle to make, unmake, and remake community.Keywords: Rizal • novels • interpretation • crowds and people • communit
