Ames Laboratory scientists took a paradoxical approach, called dynamic stabilization, by applying a terahertz electric field to drive periodic lattice oscillations in a model topological insulator. These additional fluctuations actually enhanced protected topological states.

The time-resolved nonlinear ghost imaging camera uses a nonlinear crystal to convert standard laser light to terahertz patterns, allowing the reconstruction of complex samples using a single terahertz pixel.

She might injure herself when both rotations add up and the angular momentum is transferred. Are similar phenomena also present in quantum mechanical systems? After years of preparation, a team at the TU Wien managed to
UConn researchers plan to continue to refine the technology to enhance its use in commercial and clinical applications.

While traditional microscopy techniques allow miniscule details to come into view, standard

Laser light. Credit: Barbara Jackson/Pixabay Researchers in Australia have found a way to manipulate laser light at a fraction of the cost of current technology. The discovery, published in Advanced Science, could help drive down costs in industries as diverse as telecommunications, medical diagnostics and consumer optoelectronics.

SAW-driven lateral n-i-p junction, and its electrical and optical properties. a Schematic of the device. Electron and hole surface gates induce electrons (n-region) and holes (p-region) in a GaAs quantum well, forming a lateral n-i-p junction along an etched 1D channel. A SAW is generated by applying an RF signal to a transducer (placed 1 mm
Credit: CC0 Public Domain The paradox of Schrödinger’s cat—the feline that is, famously, both alive and dead until its box is opened—is the most widely known example of a recurrent problem in quantum mechanics: its dynamics seem to predict that macroscopic objects (like cats) can, sometimes, exist simultaneously in more than one completely distinct state.
Graphically structural illustrations of the broadband 1-bit coding particles and the corresponding transmission amplitude and phase responses.

However, with the rapid development of digital information technology,
Laser pulses generate and track electronic quantum interference in an atom.

Tunable photoluminescence and lasing spectra from FAPbX3 NCs. Credit: SIOM Formamidinium (FA) perovskites have exhibited outstanding optoelectronic properties in efficient solar cells and light-emitting diodes. However, their development on nanolaser application has rarely been explored, especially the up-conversion lasing performance. Recently, a collaborative research team from Shanghai Institute of Optics and Fine Mechanics (SIOM) of
Schematic temperature-pressure-randomness phase diagram of the Mott transition system examined by the researchers. The electrons in the electronic Griffiths phase behave like soft matter. Credit: Yamamoto et al. Most theories of solid state and soft matter physics were developed independently; thus, a few physical concepts are applicable to both. Recent research, however, particularly a study
An optical cavity with a nonlinear material (purple) between two mirrors (blue). Light that enters from the left, resonates inside the cavity. Due to noise, the output on the right switches randomly between two values. A small perturbation in the cavity (like a particle, shown here as the yellow Є) changes the switching output pattern.
