Researchers Successfully Experiment Exotic Physics in Lab Crystal
A new breakthrough in the field of physics has cracked the once perceived mystery, theorizing an exotic effect in a laboratory crystal for the first time ever.
Researchers at IBM Research near Zurich have created a bizarre effect in the laboratory which was only believed to occur in intense gravitational fields, near the black hole or after the Big Bang, according to a paper published in Nature journal on July 21, 2017.
Laws of Quantum mechanics, sometimes destroys symmetry giving rise to a phenomenon called anomaly. Quantum anomalies were limited to the world of elementary particle physics explored only in huge accelerator laboratories. Now, however, a new material called Weyl semimetals is similar to 3-D graphene, has the potential of putting to work, the symmetry destructing quantum anomaly in everyday phenomena, such as the creation of electric current. This effect is known as the axial–gravitational anomaly.
“For the first time, we have experimentally observed this fundamental quantum anomaly on Earth which is extremely important towards our understanding of the universe,” said Dr. Johannes Gooth, an IBM Research scientist and lead author of the paper. “We can now build novel solid-state devices based on this anomaly that have never been considered before to potentially circumvent some of the problems inherent in classical electronic devices, such as transistors.”
New calculations using the string theory, demonstrated that this gravitational anomaly could also produce a current, if the magnet field is applied while the material is heated up.
This discovery clearly concludes that breaking of symmetry can be observed in any physical system, whether occurred at the beginning of the universe or today. This discovery has the scope for improved power consumption giving rise to new expansions around switches, sensors, thermoelectric coolers and energy-harvesting devices.
