Linear polarization holography
In conventional holography, the hologram is formed by recording the interference fringes of two coherent beams using a photosensitive material. The amplitude and phase information of the original signal wave can be reconstructed correctly when readin.....»»
Researchers realize multiphoton electron emission with non-classical light
Strong field quantum optics is a rapidly emerging research topic, which merges elements of non-linear photoemission rooted in strong field physics with the well-established realm of quantum optics. While the distribution of light particles (i.e., pho.....»»
Quantum geometry offers new insights into "smart" materials with switchable electric polarity
Quantum theorists at the University of British Columbia have proposed a new approach to studying stacking ferroelectricity—spontaneous electric polarization—in layered, two-dimensional lab-grown materials......»»
Psychological research offers strategies for healthy political discussions among people with opposing views
Civilized political debates may seem increasingly out of reach as democracies across the world face rising polarization, but people still want to discuss issues with people they disagree with—especially those who present themselves as balanced and.....»»
Rolling with the punches: How mantis shrimp defend against high-speed strikes
Mantis shrimp are small creatures known for their superlatives. Their eyes have 12 to 16 different color receptors versus our own three, and can detect the polarization of light. Their punches are famously fast, accelerating on par with a 22-caliber.....»»
Researchers demonstrate low-loss and polarization-independent integrated optical colorless ROADM
The implementation of integrated optical switches shows promise in the size reduction of ROADMs for greater flexibility and compactness, ultimately leading to robust single-chip solutions. Despite decades of research on switches with various structur.....»»
Study identifies early warning signals for the end of the African humid period
The transition from the African humid period (AHP) to dry conditions in North Africa is the clearest example of climate tipping points in recent geological history. They occur when small perturbations trigger a large, non-linear response in the syste.....»»
Contradictory thoughts lead to more moderate attitudes, psychologists find
Researchers from the Leibniz Institute for Psychology (ZPID) and the University of Hohenheim present rhetorical tools that can help to reduce the polarization of discussions......»»
Grief, unity, and resilience: Study examines the impact of memorial days in Israel
A recent study at the Hebrew University examines the impact of memorial days in Israel on national unity amidst political polarization......»»
Researchers unveil single-shot and complete polarization imaging system using metasurfaces
Think of all the information we get based on how an object interacts with wavelengths of light—aka color. Color can tell us if food is safe to eat or if a piece of metal is hot. Color is an important diagnostic tool in medicine, helping practitione.....»»
Tales of Kenzera: Zau review: emotional Metroidvania is a spiritual journey
Tales of Kenzera: Zau's linear 2D exploration is lacking, but its emotional story about grief makes up for those shortcomings......»»
Theories that explain the crisis in democracy are inadequate for Latin America, experts say
The theories offered by the dominant literature in political science today to try to explain the sources of the political polarization that has endangered democracy around the world are adequate for the United States and Europe, but do not make sense.....»»
Americans think AI will harm privacy and elections: Report
Americans are quite worried about the role artificial intelligence will play in both politics and society, according to a new report by the Polarization Research Lab......»»
On-surface synthesis of carbyne: An sp-hybridized linear carbon allotrope
In a study led by Prof. Wei Xu (Interdisciplinary Materials Research Center, School of Materials Science and Engineering, Tongji University) and published in the journal National Science Review, a research team achieved the successful synthesis of a.....»»
Advancing real-time 3D holographic display: A new method for computer-generated holography
Holographic displays offer a promising avenue for achieving lifelike 3D reproductions with continuous depth sensation, holding potential applications in fields such as entertainment, medical imaging, and virtual reality. However, the conventional met.....»»
Tesla’s $25,000 car means tossing out Henry Ford"s 100-year-old assembly line
Instead of a large, rectangular car moving along a linear conveyer belt, parts are assembled simultaneously in dedicated areas and then all put together at the end......»»
Using polarization to improve quantum imaging
Quantum imaging is a growing field that takes advantage of the counterintuitive and "spooky" ability of light particles, or photons, to become linked, or entangled, under specialized circumstances. If the state of one photon in the entangled duo gets.....»»
Polarization-sensitive tomography made easy with tensorial tomographic Fourier ptychography
In the realm of medical imaging, there are quite a few different techniques to extract information from biological tissue based on its different interactions with visible light. Over the past decade, there has been a massive surge in research focusin.....»»
Image: Barchan and linear dunes on Mars
On Jan. 16, 2020, the Mars Reconnaissance Orbiter (MRO) captured this image of two types of sand dunes on Mars: barchan and linear dunes......»»
Novel method for controlling light polarization uses liquid crystals to create holograms
Researchers have made a significant breakthrough in controlling the polarization of light, a crucial property for various applications such as augmented reality, data storage, and encryption......»»
Novel method improves Fourier transform infrared spectroscopy detection of ultra-low concentration trace substances
Recently, a research team led by Prof. Gao Minguang and Associate Prof. Li Xiangxian from Hefei Institutes of Physical Science (HFIPS), Chinese Academy of Sciences (CAS) has developed a spectral resolution enhancement method based on linear predictio.....»»
