Quantum Lifshitz point in the infinite dimensional Hubbard model
F. Günther, G. Seibold, J. Lorenzana
We show that the Gutzwiller variational wave function is surprisingly accurate for the computation of magnetic phase boundaries in the infinite dimensional Hubbard model. This allo…
Admittance of planar two-terminal quantum systems
U. Wulf, P. N. Racec, E. R. Racec
We develop an approach to calculate the admittance of effectively one-dimensional open quantum systems in random phase approximation. The stationary, unperturbed system is describe…
Unified description of charge and spin excitations of stripes in cuprates
J. Lorenzana, G. Seibold
We study stripes in cuprates within the one-band and the three-band Hubbard model. Magnetic and charge excitations are described within the time-dependent Gutzwiller approximation.…
Checkerboard and stripe inhomogeneities in cuprates
G. Seibold, J. Lorenzana, M. Grilli
We systematically investigate charge-ordering phases by means of a restricted and unrestricted Gutzwiller approximation to the single-band Hubbard model with nearest () and next…
Target mass and finite momentum transfer corrections to unpolarized and polarized diffractive scatterin
Johannes Blümlein, Bodo Geyer, Dieter Robaschik
A quantum field theoretic treatment of inclusive deep--inelastic diffractive scattering is given. The process can be described in the general framework of non--forward scattering p…
Explicit solutions for a nonlinear model of financial derivatives
Ljudmila A. Bordag, Alina Z. Chmakova
Families of explicit solutions are found to a nonlinear Black-Scholes equation which incorporates the feedback-effect of a large trader in case of market illiquidity. The typical s…
Real Computational Universality: The Word Problem for a class of groups with infinite presentation
Martin Ziegler, Klaus Meer
The word problem for discrete groups is well-known to be undecidable by a Turing Machine; more precisely, it is reducible both to and from and thus equivalent to the discrete Halti…
