A molecular fingerprint beyond the Nyquist frequency

24 avril

Ultrashort pulses play a significant role in spectroscopic applications. Their broad spectral bandwidth enables simultaneous characterization of the sample at various frequencies, eliminating the need for repeated measurements or laser tuning. Moreover, their extreme temporal confinement (…)

Scientists tune the entanglement structure in an array of qubits

24 avril

Entanglement is a form of correlation between quantum objects, such as particles at the atomic scale. The laws of classical physics cannot explain this uniquely quantum phenomenon, yet it is one of the properties that explain the macroscopic behavior of quantum systems.

A shade closer to more efficient organic photovoltaics

24 avril

Transparent solar cells will transform the look of infrastructure by enabling many more surfaces to become solar panels. Now, materials called non-fullerene acceptors that can intrinsically generate charges when exposed to sunlight could make semitransparent organic photovoltaics easier to (…)

A novel universal light-based technique to control valley polarization in bulk materials

24 avril

Electrons inside solid materials can only take certain values of energy. The allowed energy ranges are called "bands," and the space between them, the forbidden energies, is known as "band gaps." Both of them together constitute the "band structure" of the (…)

Lead-vacancy centers in diamond as building blocks for large-scale quantum networks

24 avril

Much like how electric circuits use components to control electronic signals, quantum networks rely on special components and nodes to transfer quantum information between different points, forming the foundation for building quantum systems.

Scientists develop novel one-dimensional superconductor

24 avril

In a significant development in the field of superconductivity, researchers at The University of Manchester have successfully achieved robust superconductivity in high magnetic fields using a newly created one-dimensional (1D) system. This breakthrough offers a promising pathway to achieving (…)

Making light ’feel’ a magnetic field like an electron would

24 avril

Unlike electrons, particles of light are uncharged, so they do not respond to magnetic fields. Despite this, researchers have now experimentally made light effectively "feel" a magnetic field within a complicated structure called a photonic crystal, which is made of silicon and glass.

Light stands still in a deformed crystal

24 avril

AMOLF researchers, in collaboration with Delft University of Technology, have succeeded in bringing light waves to a halt by deforming the two-dimensional photonic crystal that contains them. The researchers show that even a subtle deformation can have a substantial effect on photons in the (…)

Scientists at the MAJORANA Collaboration look for rule-violating electrons

24 avril

In a new study published inNature Physics, scientists at the MAJORANA Collaboration have tested the stringency of charge conservation and Pauli’s exclusion principles using underground detectors. Alessio Porcelli has published a News & Views piece on the research in the same journal.

Tailoring electron vortex beams with customizable intensity patterns by electron diffraction holography

23 avril

A new research study from Opto-Electronic Advances discusses tailoring electron vortex beams with customizable intensity patterns by electron diffraction holography.
