Los Angeles – insight into the black hole paradox may come from the source of the earth.
Physicist at the university of rochester, New York Sreenath Kizhakkumpurath Manikandan March 7 in a meeting of the American physical society, superconductor is electrons can move freely without impedance materials, some physics with black holes may have things in common. The analogy between the two objects can help scientists understand what happens when information is consumed in the depths of a black hole.
When a black hole devours particles, information about the properties of particles seems trapped inside. According to quantum mechanics, this information cannot be destroyed. Physicist Stephen Hawking, in 1974, determined that black holes gradually evaporate over time and emit what is known as hawking radiation before disappearing. This fact means a conundrum known as the black hole information paradox (SN: 5/31/14, p. 16) : where does the information spread when the black hole evaporates?
Stanford university physicist Patrick Hayden and John at the California institute of technology & gere in 2007 put forward a possible solution, it is that black holes may, like a mirror, the information is about the encounter particles outward reflection, printed in the hawking radiation. Now, also from the university of rochester manny dry and physicist Andrew Jordan also reported that in the process of the interface between the metal and superconductor is similar to the proposed black hole mirror.
This effect is known as the Andreev reflex when it encounters a superconductor through a metal electron. The incoming electrons have a quantum property called spin, similar to the rotation at the top. The direction of spin is a quantum information. When the incoming electron meets the superconductor, it is paired with another electron in the material, forming a double body called Cooper pairs. These pairs allow electrons to easily pass through the material to promote its superconductivity. When the original electron chooses its partner, it also leaves behind a different electron, reflecting its information back into the metal. The reflection entity is called a “hole”, a material disturbance that occurs when an electron is missing. The hole moves through the metal as if it were a particle,
Likewise, if a black hole like information mirror, as Hayden and & gill, a particle of the black hole will follow a antiparticles out – with an opposite charge partner – it will carry the information of the original particles contained in the spin. Manikandan and Jordan show that these two processes are mathematically equivalent.
It’s not yet clear whether a black hole mirror is the correct solution to the paradox, but the analogy suggests that experiments with superconductors can clarify what’s going on, Jordan said. “This is something black holes can’t do: you can’t do detailed experiments because they’re somewhere in the galaxy.”
The theory is “interesting,” says physicist Justin Dressel of chapman university in orange, California. This comparison helps scientists get insights from one area and apply them elsewhere. But Dressel says additional work is needed to determine the intensity of the analogy. “You may find that the details of further examination are different.”
