Variational functional for transition amplitudes: Improving the time-dependent Hartree-Fock method

Physical Review A, 1986
A variational expression is introduced for transition amplitudes, that is invariant under time reversal and is independent of the phases of trial states. With the use of time-dependent Hartree-Fock (TDHF) wave functions and a linear combination of atomic orbitals, exact numerical results for He+He/sup 2 +/..-->..He/sup +/+He/sup +/ obtained within a ...

Methods for reliable estimation of pulse transit time and blood pressure variations using smartphone sensors

Microprocessors and Microsystems, 2016
Hypertension is known to affect around one third of adults globally and early diagnosis is essential to reduce the effects of this affliction. Todays Blood Pressure (BP) monitoring cuffs are obtrusive and inconvenient for performing regular measurements, and continuous non-invasive blood pressure devices are too complex and expensive for ambulatory use.

A time-dependent variation–perturbation method for the calculation of transition properties and its relation to the random phase approximation

The Journal of Chemical Physics, 1975
A time−dependent variation−perturbation (VP) formulation is presented for the simultaneous calculation of the ground state correlation function and the excited state wave function of an atomic or molecular system. The wave functions are chosen for the optimal calculation of transition properties with a relatively small number of molecular integrals ...
