Light can excite electron and hole pairs inside semiconducting materials. If the attraction between a negatively charged electron and a positively charged hole (the antiparticle of electron in solid state physics) is strong, ...
Physicists have been trying to identify reliable strategies to manipulate quantum states in solid-state materials, cold atoms and other systems, as this could inform the development of new technologies. One of these strategies ...
Quantum computers, machines that leverage quantum states to perform computations and store data, could soon revolutionize the computing industry, achieving significantly greater speeds and performance than existing computers. ...
Quantum information platforms are based on qubits that talk to each other and photons (optical and microwave) are the carrier of choice—to date, to transfer quantum states between qubits. However, in some solid-state systems, ...
(Phys.org)—Stuart Kauffman, from the University of Calgary, and several of his colleagues have recently published a paper on the Arxiv server titled 'Quantum Criticality at the Origins of Life'. The idea of a quantum criticality, ...
(Phys.org) —The simple acts of heating and cooling affect different substances in different ways: some substances may change phase from solid to liquid to gas, while others may irreversibly break down when heat is applied. ...
(Phys.org) —One of the defining properties of metals is that, the hotter the metal, the worse it conducts electricity. But while most metals obey this inverse relationship between temperature and conductivity in a straightforward ...
(PhysOrg.com) -- In general, the field of many-body physics involves the interactions and collective behavior of large numbers of particles. Scientists have made significant progress in exploring this field, which has led ...
(PhysOrg.com) -- Researchers have already known that carbon nanotube thin films have mechanical and conductive advantages that could make them useful as electrodes in solar cells, solid state lighting, and electronic displays. ...
Scientists have discovered a new, intermediate state in the process of protein folding, showing folding can occur in two stages, one fast and the next found to be much slower. The findings are published in the journal Physical ...
