Hitachi’s Post

Electronic devices and motors are used in a variety of applications, including mobile phones, personal computers, cars, trains, and power plants, supporting our daily life. Many of those functions and performances are determined by the arrangement of atoms, which are the smallest unit of ordinary matter that forms material, and behavior of electrons. To develop new functions and improve performance, there is a need for a technology enabling the ultra-high-resolution observation of matter at an atomic level. Today, Hitachi, Kyushu University, RIKEN, and HREM announced the world's first observation of magnetic fields of individual lattice planes. 

Aromatic Graphene-META material I mentioned earlier that the quantum resonance of the octagonal ring within our aromatic Graphene nano structure has the ability to heal mis-ordered nano structures. This research proved it. #quantumphysicstechnology #META-materials #aromaticgraphene #NLfirstgraphenethinfilm-battery factory

🔀 We are thrilled to announce the discovery of a new type of qubit that could dramatically increase the stability of quantum hardware. This significant discovery is described in detail in a new paper “Superconducting Qubit Based on Twisted Cuprate Van der Waals Heterostructures,” published in the Physical Review Letters. 🌸 Researchers found that twisting together two thin superconducting crystals forms a structure that exponentially suppresses certain types of environmental noise. The “flowermon” qubit will make it much easier to scale up superconducting quantum processors. This design maintains high coherence without requiring highly controlled fabrication or special tuning of the system. 🔔 Professor Valerii Vinokur, Terra Quantum AG’s Chief Technology Officer US, wrote the paper with colleagues from the University of Rome, the Enrico Fermi Research Center, the Max Planck Institute, the University of Naples, City College of City University of New York and the Leibniz Institute for Solid State and Materials Science.

Our recent paper on the electron effective mass in GaN has been selected as a featured article by APL Materials. While at low temperatures the electron effective mass behaves as expected with a value of ≈0.2 m0, at room temperature we found a strong enhancement of (0.34 ± 0.03) m0. Conduction band nonparabolicity and polaron effects, combined could account only for an ∼9% increase. Interestingly, this effect is only observed at THz frequencies but not if we go to the MIR spectral range. We believe this may be caused by deviations of the free electron behavior from the classical Drude modelc, associated with a frequency-dependent scattering time.

Achieving strong photon–emitter couplings has been a long-standing challenge in cavity quantum electrodynamics. Now, recent research offers a waveguide QED alternative where 1D propagating modes replace the zero-dimensional cavity mode with an engineered spectral structure.

For the first time, experimental physicists from the Würzburg-Dresden Cluster of Excellence ct.qmat have demonstrated a new quantum effect aptly named the “spinaron.” In a meticulously controlled environment and using an advanced set of instruments, they managed to prove the unusual state a cobalt atom assumes on a copper surface. This revelation challenges the long-held Kondo effect – a theoretical concept developed in the 1960s, and which has been considered the standard model for the interaction of magnetic materials with metals since the 1980s. #nanotechnology #materialsscience #quantumtechnology #quantumcomputing #electronics #computing #technology #future

Check out of new paper on enhanced spin-charge interconversion in ferromagnetic 2-dimensional electron gases (2DEGs). 2DEGs are well known to realize efficient spin-charge interconversion due their Rashba spin-orbit coupling. Here, we show that making 2DEGs ferromagnetic can boost the spin-charge interconversion efficiency by nearly one order of magnitude. This is the first paper of our PhD student Gabriel Lazrak and a collaboration between our group at Laboratoire Albert Fert and The Martin Luther University of Halle-Wittenberg. It is published in Phys. Rev. Research (doi: 10.1103/PhysRevResearch.6.023074) of American Physical Society. https://lnkd.in/eqn_Uw8E #spintronics #lowpowercomputing
