Ground state of many-electron systems based on the action function
Peter Fulde
The Hilbert space for an interacting electron system increases exponentially with electron number . This limits the concept of wavefunctions based on solutions of the Schröd…
Ground-state wavefunction of macroscopic electron systems
Peter Fulde
Wavefunctions for large electron numbers are plagued by the Exponential Wall Problem (EWP), i.e., an exponential increase in the dimensions of Hilbert space with . Therefore…
Wavefunctions for large electronic systems
Peter Fulde
Wavefunctions for large electron numbers suffer from an exponential growth of the Hilbert space which is required for their description. In fact, as pointed out by W. Kohn, for ele…
Dealing with the exponential wall in electronic structure calculations
Peter Fulde, Hermann Stoll
An alternative to Density Functional Theory are wavefunction based electronic structure calculations for solids. In order to perform them the Exponential Wall (EW) problem has to b…
Critical magnetic field of ultrathin superconducting films and interfaces
Gertrud Zwicknagl, Simon Jahns, Peter Fulde
We derive an analytic expression for the temperature dependent critical magnetic field parallel to ultrathin superconducting films with Rashba spin-orbit interaction. Thereby we co…
Covalency and vibronic couplings make a nonmagnetic j=3/2 ion magnetic
Lei Xu, Nikolay A. Bogdanov, Andrew Princep +3
For 4 and 5 spin-orbit-coupled electron configurations, the notion of nonmagnetic j=3/2 quartet ground state discussed in classical textbooks is at odds with the observed…
