A new study determines the thermal properties of advanced solid materials, based on first-principles calculations of quantum vibrations.
Visible light is a mere fraction of the electromagnetic spectrum, and the manipulation of light waves at frequencies beyond human vision has enabled such technologies as cell phones and CT scans.
A research team led by Prof. Chen Xianhui from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS), collaborating with the team led by Prof. Sun Jian from Nanjing University, ...
Thermal superinsulation materials with low thermal conductivities are essential for thermal insulation and protection under extreme conditions. These materials are particularly required in fields including deep-space exploration, ...
Molecules immersed in liquid helium can probe superfluidity since their electronic, vibrational and rotational dynamics can provide valuable cues about the superfluid at the nanoscale. In a new report in Science Advances, ...
Lasers are a significant historical invention with ubiquitous impact in society. The concept also has interdisciplinary applications as phonon lasers and atom lasers. A laser in one physical domain can be pumped by energy ...
A new approach to developing semiconductor materials at tiny scales could help boost applications that rely on converting light to energy. A Los Alamos-led research team incorporated magnetic dopants into specially engineered ...
New research sheds light on the mechanism behind how a special material changes from an electrically conducting metal to an electric insulator. The researchers studied lanthanum strontium nickel oxide (La1.67Sr0.33NiO4) derived ...
Nothing exists in a vacuum, but physicists often wish this weren't the case. If the systems that scientists study could be completely isolated from the outside world, things would be a lot easier.
When you turn on a lamp to brighten a room, you are experiencing light energy transmitted as photons, which are small, discrete quantum packets of energy. These photons must obey the sometimes strange laws of quantum mechanics, ...
