This has involved a combination of analytically solvable models, as well as the development of new numerical methods that provide approximate solutions given a microscopic (lattice scale) Hamiltonian. Much work has been done to address specific models and connect them to experimental analogs. Although most studies have focused on gapped spin liquids, equally intriguing are gapless versions-for instance, ones where the quasiparticle (“spinon”) spectrum is that of relativistic electrons described by the Dirac equation. One consequence is that these quasiparticle excitations can have nontrivial statistical interactions when they are braided around each other.
Specifically, they describe excitations that carry a fraction of the quantum of spin in terms of emergent quasiparticles with gauge charge and/or gauge flux, analogous to the electric charge and magnetic flux in electrodynamics. However, these gauge fields are “emergent” in the sense that they reflect important structure of the many-particle state. Of particular note was the realization that an effective low-energy theory inevitably resembles the gauge theory treatments also invoked in high-energy physics.

Here you will find reasonable product details. This is Barefoot Power Firefly Lamp for your favorite. Visit product Barefoot Power Firefly Lamp. Note for users: to prevent inadvertent discharge, the circuit prevents light from turning on when plugged in to the solar panel. 2% of all profits from Amazon sales will be used to seed a micro-credit fund for lamps in developing countries, or to procure lamps for remote medical clinics. Competing against lighting giants like Philips, Barefoot won 3 of the 4 product quality awards offered by Lighting Africa, an IFC / World Bank project in 2010. Barefoot Power products are among the best out there. These bright, robust, versatile solar LED lights are replacing kerosene as the main lighting source in providing light to the homes of over 2 million people in Kenya, Uganda, Papua New Guinea, and 17 other countries. The F10-mobile, also available on our storefront, does charge cell phones. This particular version (1.0 watt) does not charge cell phones. Carbon revenue will contribute to the affordability and improved quality and performance of Barefoot Power products.
It is designed and developed to meet the UN Clean Development Mechanism standards. When fully charged, the Firefly Light will provide 4 hrs of bright light or 50 hrs of light on the night light setting. The included high-output 1 watt solar panel will fully change the lamp with 5 hours of direct sunlight. It works great as desk lamp, a flashlight, or a night light. New lithium-ion batteries provide 1000 cycles. The Firefly utilizes 5 super bright SMD LEDs, producing 16 lumens of of even light.
