The phenomenological spin gap, which is linear in B at high magnetic field, collapses when the spin splitting collapses. This is consistent with previously proposed disorder-driven destruction of exchange interactions with decreasing magnetic field....
spin-orbit interactionstwo-dimensional electron gas/ exchange-enhanced spin-splittingWe present a theoretical study on how many-body effects can affect the spin-splitting of a two-dimensional electron gas in the presence of the Rashba spin–orbit interaction. The standard Hartree–Fock approximation ...

Collapse of spin-splitting and an enhanced Lande´ |g|-factor at Landau level filling factors both ν=3 and 1 are observed. Our experimental results show direct evidence that the electron–electron interactions are stronger at ν=3 than those at ν=1 over approximately the same perpendicular ...
Moreover, the splitting follows the magnetization of EuS, a hallmark of the MEF. Utilizing the MEF of a magnetic insulator can induce magnetic order and valley and spin polarization in TMDCs, which may enable valleytronic and quantum-computing applications.Chuan...
High-valent manganese-oxo complexes are currently in high demand because of their efficient catalysis of C-H bond activation, their implications as intermediates during water splitting, for example in photosystem II, and their antioxidant activity. Many of these oxidation processes occur by an initial...
Sping-FactorGaAsWe have measured the low-temperature transport properties of front-gated GaAs/Al0.33Ga0.67As heterostructures. Collapse of spin-splitting and an enhanced Landé |g|-factor at Landau level filling factors both ν=3 and 1 are observed. Our experimental results show direct evidence ...
