Researchers observe Floquet states in colloidal nanoplatelets driven by visible pulses
Solution-processed semiconductor nanocrystals are also called colloidal quantum dots (QDs). While the concept of size-dependent quantum effects had long been known to physicists, a sculpture of the theory into real nanodimensional objects remained im.....»»
Correcting misperceptions of opposing party won"t reduce polarization, study finds
Political animus between Republicans and Democrats in the United States is alarmingly high, raising fears of undemocratic or even violent actions. An often-touted intervention to prevent political polarization is to identify and correct misperception.....»»
Physicists successfully observe Kibble–Zurek scaling in an atomic Fermi superfluid
The Kibble–Zurek (KZ) mechanism is a theoretical framework introduced by physicists Tom Kibble and Wojciech Zurek. This framework essentially describes the formation of topological defects while systems undergo non-equilibrium phase transitions......»»
Ultrathin quantum light sources: Scientists show excitonic interactions boost efficiency of entangled photon generation
Scientists from the National University of Singapore (NUS) have shown that excitonic resonances and transitions between excitons can significantly increase the efficiency of generating entangled photon pairs. This could lead to the development of eff.....»»

Theoretical research holds promise for advancing modular quantum information processing
The operation of a quantum computer relies on encoding and processing information in the form of quantum bits—defined by two states of quantum systems such as electrons and photons. Unlike binary bits used in classical computers, quantum bits can e.....»»
New insights into neural circuit imaging: A comparison of one-photon and two-photon techniques
In the quest to unravel the complexities of neural circuits, scientists are beginning to use genetically encoded voltage indicators (GEVIs) to visualize electrical activity in the brain. These indicators are crucial for understanding how neurons comm.....»»
New parameter enhances insights into the evolution of mantle"s redox states
The oxygen fugacity (fO2) of the mantle controls the speciation and mobility of volatiles within it, influencing the composition of volatiles released during mantle-derived magmatic activity, and thereby regulating the composition of the atmosphere......»»
"Mirror" nuclei help connect nuclear theory and neutron stars
Adding or removing neutrons from an atomic nucleus leads to changes in the size of the nucleus. This in turn causes tiny changes in the energy levels of the atom's electrons, known as isotope shifts. Scientists can use precision measurements of these.....»»
