Anomalous low-energy -related behavior in triaxial nuclei
Yu Zhang, Ying-Wen He, D. Karlsson +3
The anomalous low-energy -related behavior of a triaxially-deformed nucleus bas been identified and analyzed based on the SU(3) algebraic theory within the framework of the int…
Cutting rules and positivity in finite temperature many-body theory
Markku J. Hyrkäs, Daniel Karlsson, Robert van Leeuwen
For a given diagrammatic approximation in many-body perturbation theory it is not guaranteed that positive observables, such as the density or the spectral function, retain their p…
A many-body approach to transport in quantum systems: From the transient regime to the stationary state
M. Ridley, N. W. Talarico, D. Karlsson +2
We review one of the most versatile theoretical approaches to the study of time-dependent correlated quantum transport in nano-systems: the non-equilibrium Green's function (NEGF)…
