Centrifugal separation of antiprotons and electrons is observed, the first such demonstration with particles that cannot be laser cooled or optically imaged. The spatial separation takes place during the electron cooling of trapped antiprotons, the only method available to produce cryogenic antiprotons for precision tests of fundamental symmetries and for cold antihydrogen studies. The centrifu...
When does a sequence of spherical codes with “good” spherical cap discrepancy, and “good” separation also have “good” Riesz s-energy? For d > 2 and the Riesz s-energy for 0 < s < d, we consider asymptotically equidistributed sequences of S codes with an upper bound δ on discrepancy and a lower bound ∆ on separation. For such sequences, the difference between the normalized Riesz s-energy and th...
The supersymmetric formulation of t-J model is studied in this paper at the mean-field level where the δ-T phase diagram is computed. We find that slave-fermion-like spiral phase is stable at low doping concentration, and the slave-boson-like d-wave fermionic spin pairing state becomes energetically favourable when δ ≥ 0.23. An improvement in free energy using Gutzwiller's method lowers the tra...
Photosynthesis is one of the most essential biological processes in which specialized pigment-protein complexes absorb solar photons, and with a remarkably high efficiency, guide the photo-induced excitation energy toward the reaction center to subsequently trigger its conversion to chemical energy. In this work, we review the principles of optimal energy transfer in various natural and artific...
