Time-resolved x-ray absorption spectroscopy: Watching atoms dance
The introduction of pump-probe techniques to the field of x-ray absorption spectroscopy (XAS) has allowed the monitoring of both structural and electronic dynamics of disordered systems in the condensed phase with unprecedented accuracy, both in time and in space. We present results on the electronically excited high-spin state structure of an Fe(II) molecular species, [Fe(bpy)3] , in aqueous s...
متن کاملMagnetic Semiconfinement of Neutral Atoms
A mechanism for creating well-collimated beams of neutral particles or atoms with spins is studied. The consideration is accomplished for a general realistic case, taking into account: (i) the finiteness of a cylindrical trap where the atoms to be shot out, are stored; (ii) the possibility of manipulating the trap magnetic fields in order to form different anisotropic field configurations; (iii...
متن کاملHow fast do stabilizer Hamiltonians thermalize?
We present rigorous bounds on the thermalization time of the family of quantum mechanical spin systems known as stabilizer Hamiltonians. The thermalizing dynamics are modeled by a Davies master equation that arises from a weak local coupling of the system to a large thermal bath. Two temperature regimes are considered. First we clarify how in the low temperature regime, the thermalization time ...
متن کاملCompeting effects in the magnetic polarization of non-magnetic atoms.
The magnetic polarization of the Lu 5d states through the Ho(1-x)Lu(x)(Fe(1-y)Al(y))(2) series has been studied by means of x-ray magnetic circular dichroism. A combined study of the dichroic signals performed at the Fe K-, Ho L(2)- and Lu L(2,3)-edges gives a complete picture of the polarization scheme at the conduction band. The results show that in the presence of competing localized magneti...
