Extremal quantum correlation generation using a hybrid channel
In this section, we give the details of the obtained results for the generation and dynamics of quantum discord, non-classical correlations, entanglement, and entropy using TDD, CN, LQU, and LE measures given in Eqs. (17), (18), (21) and (23). The results are based on the final density matrix’s elements given in Eq. (13) when the…

Simulations reveal the atomic-scale story of qubits
Investigated atomic pathways in 3C-SiC. a) Monovacancy dynamics, including carbon (VC) and silicon (VSi) vacancy migration, and VSi and carbon antisite vacancy complex (CAV) inter-conversion. b) Pairing of second (V-V2) and third (V-V3) neighbors VC and VSi vacancies to form a double vacancy VV. Only V-V up to third neighbors were considered, due to the…

Electrons in a strange metal world
Imagine a flock of birds as they wheel across the sky: surging into a mass, flowing into ribbons that twist and turn again into fantastic shapes. If you follow one bird within the flock, you can describe its actions, the way it flaps its wings or uses its tail to brake. Yet, even if you…

Study employs deep learning to explain extreme events
Credit: FAU College of Engineering and Computer Science Identifying the underlying cause of extreme events such as floods, heavy downpours or tornados is immensely difficult and can take a concerted effort by scientists over several decades to arrive at feasible physical explanations. Extreme events cause significant deviation from expected behavior and can dictate the overall…

Turbulent Jets Doubly Detrimental to Fluid-Based Batteries
October 2, 2023• Physics 16, s141 Jets that develop along the walls of fluid-based thermal-energy-storage systems induce multiple flows that limit the devices’ ability to store energy. Converting waste heat from renewable-energy technologies into electricity could reduce the need for fossil-fuel power stations—but only if that energy can be stored efficiently, for example, in a…
