A tracker solution to the cold dark matter cosmic coincidence problem

, 1999
Recently, we introduced the notion of "tracker fields," a form of quintessence which has an attractor-like solution. Using this concept, we showed how to construct models in which the ratio of quintessence to matter densities today is independent of ...

Infrared Nanocrystals for Space Application: Hardness to Irradiations

Advanced Functional Materials, EarlyView.
This article investigates infrared HgTe nanocrystals under X‐ray and ion irradiation, revealing remarkable radiation hardness. It uncovers distinct degradation mechanisms and shows that the nanomaterial outperforms integrated electronics. The results position colloidal nanocrystals as promising candidates for resilient space and harsh‐environment ...

Laser‐Microscribed Glass Enables Surface‐Microfluidics‐Facilitated, Affordable, Rapid Cancer Diagnosis

Advanced Functional Materials, EarlyView.
A transparent, laser‐microscribed glass platform enables cancer diagnosis within 1 h—much faster than histology, which takes days, and free from the chemical or contrast risks of MRI or CT scans. The antibody‐functionalized rough glass surface captures viable cancer cells directly from suspension, allowing instant optical readout and offering a rapid ...

LOCKED QUINTESSENCE AND COLD DARK MATTER [PDF]

The Identification of Dark Matter, 2005
A supersymmetric hybrid potential model with low energy supersymmetry breaking scale ($ M_{S}\sim 1-10 Tev$) is presented for both dark matter and dark energy. Cold dark matter is associated with a light modulus field ($\sim 10-100 Mev$) undergoing coherent oscillations around a saddle point false vacuum with the presently observed energy density ($ _{

Stellar Cores Live Long and Prosper in Cuspy Dark Matter Halos

The Astrophysical Journal Letters
The existence of cuspy or cored centers of dark matter halos is a crucial discriminant between different dark matter models. It has recently been claimed based on dynamical arguments that perfectly cored stellar systems cannot survive inside cuspy dark ...

On an interacting ghost dark energy model in a non-flat universe with accelerating expansion

Papers in Physics
An interacting ghost dark energy with experimental constraint in a non-flat universe with accelerating expansion is studied in this report. Based on the linear relationship between dark energy and the Hubbard function, it is found that the non ...

Cold dark matter with MOND scaling

Physics Letters B, 2010
We provide a holographic dual description of Milgrom's scaling associated with galactic rotation curves. Our argument is based on the recent entropic reinterpretation of Newton's laws of motion. We propose a duality between cold dark matter and modified Newtonian dynamics (MOND).
