Research reveals exotic quantum states in double-layer graphene（图）
exotic quantum states double-layer graphene
2019/10/23
NSF-funded research by scientists at Brown and Columbia Universities has demonstrated the existence of previously unknown states of matter that arise in double-layer stacks of graphene, a two-dimensio...
Creation of NOON states by double Fock-state/Bose-Einstein condensates
State of single particle state variable theory the measuring accuracy measuring phase the condensate
2014/12/19
NOON states (states of the form |N〉 a |0〉 b +|0〉 a |N〉 b where a and b are single particle states) have been used for predicting violations of hidden-variable theories (Greenbe...
Two-spin dephasing by electron-phonon interaction in semiconductor double quantum dots
Two-spin dephasing electron-phonon interaction semiconductor double quantum dots
2010/11/11
We study electron-phonon interaction induced decoherence between two-electron singlet and triplet states in a semiconductor double quantum dot using a spin-boson model. We investigate the onset and ti...
First Measurement of the Muon Neutrino Charged Current Quasielastic Double Differential Cross Section
Charged Current Quasielastic neutrino oscillations
2010/3/15
A high-statistics sample of charged-current muon neutrino scattering events collected with the MiniBooNE experiment is analyzed to extract the first measurement of the double differential cross sectio...
DC Electric Field Effects on the Electron Dynamics in Double Rectangular Quantum Dots
Coupled quantum dots DC bias Coherence Relaxation
2010/9/25
The effect of a dc electric field on the temporal evolution of an electron in a double rectangular quantum dot is explored in this work. In the framework of the effective mass approximation, first-ord...
Donor-Related Optical Absorption Spectra for a GaAs-Ga0.7Al0.3As Double Quantum Well under Hydrostatic Pressure and Applied Electric Field Effects
Electric field Hydrostatic pressure Quantum well Absorption spectra
2010/9/25
The hydrostatic-pressure and applied electric field dependencies of the binding energy and the opticalabsorption spectra, associated with transitions between the n = 1 valence subband and the donor-im...
Structural, Electrical and Spectral Studies on Double Rare-Earth Orthoferrites La1-xNdxFeO3
Orthoferrite X-ray Electrical properties IR
2010/4/12
Samples of double rare-earth ferrite La1-xNdxFeO3 are synthesized by a high-temperature double sintering ceramic technique. X-ray diffraction shows that all compounds have an orthorhombic structure. T...
