  1. Photovoltaic Nanotubes
    6/20/2019

    Physicists discovered a novel kind of nanotube that generates current in the presence of light. Devices such as optical sensors and infrared imaging chips are likely applications, which could be useful in fields such as automated transport and astronomy. In future, if the effect can be magnified and the technology scaled up, it could lead to high-efficiency solar power devices.

  2. A Sound Idea: A Step Towards Quantum Computing Using Vibrations In Silicon
    6/19/2019

    A team at the University of Tsukuba studied a novel process for creating coherent lattice waves inside silicon crystals using ultrashort laser pulses. Using theoretical calculations combined with experimental results that were obtained at the University of Pittsburgh, they were able to show that coherent vibrational signals could be maintained inside the samples.

  3. Researchers Find Quantum Gravity Has No Symmetry
    6/19/2019

    A new study by a pair of researchers in the US and Japan has found that, when gravity is combined with quantum mechanics, symmetry is not possible.

  4. Secure Quantum Communications In The Microwave Range For The First Time
    6/18/2019

    Mikel Sanz, of the Physical Chemistry Department of UPV/EHU, leads the theoretical group for an experiment published by the prestigious magazine, Nature Communications. The experiment has managed to prepare a remote quantum state; i.e., absolutely secure communication was established with another, physically separated quantum computer for the first time in the microwave regime. This new technology may bring about a revolution in the next few years.

  5. Gold Nanoparticle Clusters For Simultaneous Photo-Thermal Imaging And Therapy
    6/18/2019

    NUS chemists have found that gold nanoparticle clusters can be used in photo-thermal therapy for imaging and treatment of human prostate cancer.

  6. A New Force For Optical Tweezers Awakens
    6/18/2019

    When studying biological cells using optical tweezers, one main issue is the damage caused to the cell by the tool. Giovanni Volpe, University of Gothenburg, has discovered a new type of force that will greatly reduce the amount of light used by optical tweezers – and improve the study of all kinds of cells and particles.

  7. ‘Double-Slit’ Quantum Experiment Shows Strangeness Of Quantum Uncertainty
    6/17/2019

    An experiment proposed at Griffith University and performed at the University of Science and Technology of China (USTC) has shown that quantum uncertainty can be enforced in a strange, non-local way, even with just a single particle.

  8. You Don’t Have To Be Perfect For TMDCs To Shine Bright
    6/17/2019

    Atomically thin semiconductors known as TMDCs (transition metal dichalcogenides) could lead to devices that operate more efficiently than conventional semiconductors in light-emitting diodes, lasers, and solar cells. But these materials are hard to make without defects that dampen their performance.

  9. Ring Resonators Corner Light
    6/17/2019

    Researchers at the Joint Quantum Institute (JQI) have created the first silicon chip that can reliably constrain light to its four corners. The effect, which arises from interfering optical pathways, isn't altered by small defects during fabrication and could eventually enable the creation of robust sources of quantum light.

  10. II-VI Incorporated Introduces High Power Collimated Laser Bars And Collimated Semi-Framed Stacks For Direct Diode And DPSS Lasers
    6/17/2019

    II‐VI Incorporated (Nasdaq:IIVI), a leader in high power semiconductor lasers, today announced the introduction of its high power laser bars and semi-framed stacks mounted with micro-optic collimator lenses, offering customers very cost-effective modular assemblies that have high performance and reliability and can be easily integrated into direct diode lasers and diode-pumped solid state (DPSS) lasers.
