Quantum-coherent light-electron interaction in an SEM [PDF]
, 2021 The last two decades experimentally affirmed the quantum nature of free electron wavepackets by the rapid development of transmission electron microscopes into ultrafast, quantum-coherent systems. In particular, ultrafast electron pulses can be generated and timed to interact with optical near-fields, yielding coherent exchange of the quantized photon ...

Periodic plane-wave electronic structure calculations on quantum computers
Materials Theory, 2023 A procedure for defining virtual spaces, and the periodic one-electron and two-electron integrals, for plane-wave second quantized Hamiltonians has been developed, and it was validated using full configuration interaction (FCI) calculations, as well as ...

Analysis of Intrinsic Switching Losses in Superjunction MOSFETs Under Zero Voltage Switching
Energies, 2020 Switching losses of power transistors usually are the most relevant energy losses in high-frequency power converters. Soft-switching techniques allow a reduction of these losses, but even under soft-switching conditions, these losses can be significant ...

Computational complexity in electronic structure [PDF]
Phys. Chem. Chem. Phys., 2013 In quantum chemistry, the price paid by all known efficient model chemistries is either the truncation of the Hilbert space or uncontrolled approximations. Theoretical computer science suggests that these restrictions are not mere shortcomings of the algorithm designers and programmers but could stem from the inherent difficulty of simulating quantum ...
