We investigate ultrafast harmonic generation (HG) in Si: B, driven by intense pump pulses with fields reaching sim100\phantomrule{0.28em0ex}kV\phantomrule{0.16em0ex}cm^-1 and a carrier frequency of 300 GHz, at 4 K and 300 K, both experimentally and theoretically. We report several findings concerning the nonlinear charge carrier dynamics in intense sub-THz fields: (i) Harmonics of order up to $n=9$ are observed at room temperature, while at low temperature we can resolve harmonics reaching at least $n=11$. The susceptibility per charge carrier at moderate field strength is as high as for charge carriers in graphene, considered to be one of the materials with the strongest sub-THz nonlinear response.

The idea of simulating quantum physics with controllable quantum devices had been proposed several decades ago. With the extensive development of quantum technology, large-scale simulation, such as the analog quantum simulation tailoring an artificial Hamiltonian mimicking the system of interest, has been implemented on elaborate quantum experimental platforms. However, due to the limitations caused by the significant noises and the connectivity, analog simulation is generically infeasible on near-term quantum computing platforms. Here we propose an alternative analog simulation approach on near-term quantum devices. Our approach circumvents the limitations by adaptively partitioning the bath into several groups based on the performance of the quantum devices.

The single-dose shot, called Ixchiq, is designed to prevent an illness that can cause debilitating joint pain for months to years.

Neuralink reportedly aims to implant its device into 11 humans next year. Elon Musk said it will be inserted by robot.

NASA astronaut Frank Borman, commander of the first Apollo mission to the moon, has died at age 95.

Researchers at Rice University found that chiral phonons in a crystal can magnetize the material, aligning electron spins in a way similar to the effect of a strong magnetic field. This discovery challenges established notions in physics, particularly the concept of time-reversal symmetry, and paves the way for advanced research in quantum materials.

Quantum materials hold the key to a future of lightning-speed, energy-efficient information systems. The problem with tapping their transformative potential is that, in solids, the vast number of atoms often drowns out the exotic quantum properties electrons carry.

Rice University researchers in the lab of quantum materials scientist Hanyu Zhu found that when they move in circles, atoms can also work wonders: When the atomic lattice in a rare-earth crystal becomes animated with a corkscrew-shaped vibration known as a chiral phonon, the crystal is transformed into a magnet.

Oak Ridge National Laboratory’s research in quantum biology and AI has significantly improved the efficiency of CRISPR Cas9 genome editing in microbes, aiding in renewable energy development.

Scientists at Oak Ridge National Laboratory (ORNL) used their expertise in quantum biology, artificial intelligence, and bioengineering to improve how CRISPR Cas9 genome editing tools work on organisms like microbes that can be modified to produce renewable fuels and chemicals.

CRISPR is a powerful tool for bioengineering, used to modify genetic code to improve an organism’s performance or to correct mutations. The CRISPR Cas9 tool relies on a single, unique guide RNA.

In an interesting revelation, a collaborative team of researchers across various institutions in London has shown that rocket scientists and neurosurgeons, who are often held on a high pedestal for their superior intellect are, in fact, no smarter than the general public, BBC reported.

When failing to complete day-to-day tasks, one often comes across the term “It’s not rocket science”. The phrases that have been used by the public at large tacitly imply that rocket science or brain surgery is not a menial job and requires an individual of a higher intellect. Interestingly, it was a team of neurosurgeons and those involved in studying the human brain who decided to probe whether this held true.

Osteonecrosis is a disease caused by reduced blood flow to bones in the joints. In people with healthy bones, new bone is always replacing old bone. In osteonecrosis, the lack of blood causes the bone to break down faster than the body can make enough new bone. The bone starts to die and may break down.

You can have osteonecrosis in one or several bones. It is most common in the upper leg. Other common sites are your upper arm and your knees, shoulders and ankles. The disease can affect men and women of any age, but it usually strikes in your thirties, forties or fifties.

At first, you might not have any symptoms. As the disease gets worse, you will probably have joint pain that becomes more severe. You may not be able to bend or move the affected joint very well.
