Fast Diffusion Mechanism of Silicon Tri-interstitial Defects
Yaojun A. Du, Stephen A. Barr, Kaden R. A. Hazzard +3
We reveal the microscopic self-diffusion process of compact tri-interstitials in silicon using a combination of molecular dynamics and nudged elastic band methods. We find that the…
Synthesizing arbitrary two-photon polarization mixed states
Tzu-Chieh Wei, Joseph B. Altepeter, David Branning +6
Two methods for creating arbitrary two-photon polarization pure states are introduced. Based on these, four schemes for creating two-photon polarization mixed states are proposed a…
Rotating Bose-Einstein condensates with attractive interactions
G. M. Kavoulakis, A. D. Jackson, Gordon Baym
We examine the phase diagram of a Bose-Einstein condensate of atoms, interacting with an attractive pseudopotential, in a quadratic-plus-quartic potential trap rotating at a given…
Intergalactic H_2 Photodissociation and the Soft UV Background Produced by Population III Objects
Benedetta Ciardi, Andrea Ferrara, Tom Abel
We study the effects of the ionizing and dissociating photons produced by PopIII objects on the surrounding intergalactic medium. We find that the typical size of a H_2 photodissoc…
