Mirror Matter, Mirror Gravity and Galactic Rotational Curves
A bigravity theory where the normal and dark matter components are coupled to separate metric fields linked to each-other with small non-derivative terms allows the Yukawa-like modification of the gravitational potential at large distances. This opens new prospects for the dark matter candidates. Namely, instead of being cold and collisionless, dark matter can be collisional and dissipative, as...
متن کاملMirror Curves
BRIDGES Mathematical Connections in Art, Music, and Science Mirror curves are present in ethnical art, as Tamil threshold designs or Tchokwe sand drawings. Historically, they are to be found in the art of most peoples surrounding the Mediterranean, the Black and Caspian Seas, in the art of Egyptians, Greeks, Romans, Byzantines, Moors, Persians, Turks, Arabs, Syrians, Hebrews and African tribes....
متن کاملTopological recursion and mirror curves
We study the constant contributions to the free energies obtained through the topological recursion applied to the complex curves mirror to toric Calabi-Yau threefolds. We show that the recursion reproduces precisely the corresponding Gromov-Witten invariants, which can be encoded in powers of the MacMahon function. As a result, we extend the scope of the “remodeling conjecture” to the full fre...
متن کاملMirror Symmetry and Elliptic Curves
I review how recent results in quantum eld theory con-rm two general predictions of the mirror symmetry program in the special case of elliptic curves: (1) counting functions of holomorphic curves on a Calabi-Yau space (Gromov-Witten invariants) arèquasi-modular forms' for the mirror family; (2) they can be computed by a summation over trivalent Feynman graphs.
متن کاملMirror Matter-type Dark Matter
There are six main things which any non-baryonic dark matter theory should endeavour to explain: (1) The basic dark matter particle properties [mass, stability, darkness]; (2) The similarity in cosmic abundance between ordinary and non-baryonic dark matter, Ω B ∼ Ω dark ; (3) Large scale structure formation; (4) Microlensing (MACHO) events; (5) Asymptotically flat rotation curves in spiral gala...
