Laser technology confines light inside a resonator containing a gain medium, a material with quantum properties that can amplify light. As laser resonators are generally far larger than the wavelength of light, lasing inside their cavities can occur in a wide range of...
Sometimes, physics theories and constructs can also be used to study seemingly unrelated phenomena, such as social behaviors or dynamics. While human beings are not necessarily similar to specific physical particles, theories or techniques that physicists typically...
Physicists have been studying superfluid 3He under nanoscale confinement for several years now, as this unique liquid presents a rich variety of phases with complex order parameters that can be stabilized. While past studies have gathered many interesting...
The concept of universal physics is intriguing, as it enables researchers to relate physical phenomena in a variety of systems, irrespective of their varying characteristics and complexities. Ultracold atomic systems are often perceived as ideal platforms for...
Echoes, sounds that are repeated or reverberate as a result of waves reflected back to the listener, occur in several physical systems. In physics research, echoes are typically used to eliminate the effects of dephasing caused by a system's interactions with the...
For almost a century, astronomers have hypothesized that the universe contains more matter than what can be observed by the human eye. It is now believed that approximately 80 percent of the universe's mass is made up of a type of matter that does not emit light or...
Researchers at ETH Zürich and National University of Singapore have carried out a study investigating whether advantage distillation, a classical cryptography technique that has so far never been successfully implemented, can be applied to device-independent quantum...
Quantum-enhanced metrology has been an active area of research for several years now due to its many possible applications, ranging from atomic clocks to biological imaging. Past physics research established that having a non-classical probe, such as squeezed light or...
New physical behavior, such as Mott insulating behavior, unconventional superconductivity and quantum spin liquid behavior, occurs when electrons inside a material interact with each other. When electrons are confined to lower dimensions such as 2-D planes, these...
Spin-orbit torque (SOT) magnetization switching is a phenomenon induced by a spin current, which is in turn generated by a charge current. Eliciting this phenomenon could help to manipulate the magnetization in spintronic devices, potentially increasing their...
