Under extreme pressure, the chemical properties of the elements we are familiar with no longer apply. For different pressure conditions, we need a new periodic table of elements. Diamond is a well-known material formed under high pressure. If you place carbon 100 miles deep on the earth, its pressure is nearly 50,000 times higher than the pressure on the surface of the earth, and the temperature is higher than 2000 degrees Fahrenheit.
However, when it comes to high-energy density physics, this pressure level is still low. At more extreme pressures, such as 2 million atmospheres, sodium can be converted into an insulator; at 10 million atmospheres, hydrogen can become a superconducting superfluid; when the pressure exceeds 200 million atmospheres, aluminum can become Transparent.
Many people think that the laser pointer is just a high temperature heat source. As everyone knows, lasers can also be used as a highly concentrated source of pressure; and OMEGA green laser pointer allows us to study materials under millions to billions of atmospheric pressure. Understanding the behavior of atoms under extreme pressure will allow researchers to deliberately process matter to form new and unusual materials.
It enjoys a high international reputation and is suitable for leading the university’s projects. He pointed out that facilities such as the Laser Lab and Lawrence Livermore ’s National Ignition Device have opened up new frontiers of high-energy density physics and ensured the leadership of the United States in this field. For creating new materials, high-energy density physics can provide more. The deputy director of the Laser Energetics Laboratory called this field “enduring science.”
He pointed out: “There will always be new areas to be explored, including the nature of the universe itself. The pressure in the center of the planet exceeds millions of times of atmospheric pressure, and the pressure of stars is billions of times of atmospheric pressure. High-energy density physics can help We understand how planets and stars are generated, like the earth has a magnetic field; and the radiation and energy flow in the sun and other stars.
