Wakker, K.F. (author)This book deals with the motion of the center of mass of a spacecraft; this discipline is generally called astrodynamics. The book focuses on an analytical treatment of the motion of spacecraft and provides insight into the fundamentals of spacecraft orbit dynamics. A large number of topics are treated in a uniform and consistent way. The text...book 2015

Wakker, G.M.M. (author), Ockhorst, R. (author), Blaauboer, M. (author)We investigate an extended version of the quantum Ising model which includes beyond-nearest-neighbor interactions and an additional site-dependent longitudinal magnetic field. Treating the interaction exactly and using perturbation theory in the longitudinal field, we calculate the energy spectrum and find that the presence of beyond-nearest...journal article 2012

Wakker, G.M.M. (author), Tiwari, R.P. (author), Blaauboer, M. (author)We calculate the energy spectrum and eigenstates of a graphene sheet that contains a circular deformation. Using time-independent perturbation theory with the ratio of the height and width of the deformation as the small parameter, we find that due to the curvature the wave functions for the various states acquire unique angular asymmetry.We...journal article 2011

Wakker, G.M.M. (author)This thesis consists of a theoretical exploration of quantum transport phenomena and quantum dynamics in nanostructures. Specifically, we investigate adiabatic quantum pumping of charge in several novel types of nanostructures involving open quantum dots or graphene. For a bilayer of graphene we find that at the Dirac point and for a wide...doctoral thesis 2011

Wakker, G.M.M. (author), Blaauboer, M. (author)We investigate quantum pumping of massless Dirac fermions in an ideal (impurity free) double layer of graphene. The pumped current is generated by adiabatic variation in two gate voltages in the contact regions to a weakly doped double graphene sheet. At the Dirac point and for a wide bilayer with width W?length L, we find that the pumped...journal article 2010

Wakker, P.P. (author), Jansen, S.J.T. (author), Stiggelbout, A.M. (author)This paper introduces anchor levels as a new tool for multiattribute utility theory. Anchor levels are attribute levels whose values are not affected by other attributes. They allow for new interpretations and generalizations of known representations and utility measurement techniques. Generalizations of earlier techniques can be obtained...journal article 2004
