New Formulation and Implementation of Vibrational Self-Consistent Field Theory
Hansen, Mikkel B.; Sparta, Manuel; Seidler, Peter; Toffolı, Danıele; Christiansen, Ove (2010-01-01)
A new implementation of the vibrational self-consistent field (VSCF) method is presented on the basis of a second quantization formulation. A so-called active terms algorithm is shown to be a significant improvement over a standard implementation reducing the computational effort by one order in the number of degrees of freedom. Various types of screening provide even further reductions in computational scaling and absolute CPU time. VSCF calculations on large polyaromatic hydrocarbon model systems are pres...

New exact solutions of quadratic curvature gravity
GÜRSES, METİN; Sisman, Tahsin Cagri; Tekin, Bayram (2012-07-03)
It is a known fact that the Kerr-Schild type solutions in general relativity satisfy both exact and linearized Einstein field equations. We show that this property remains valid also for a special class of the Kerr-Schild metrics in arbitrary dimensions in generic quadratic curvature theory. In addition to the anti-de Sitter (AdS) wave (or Siklos) metric which represents plane waves in an AdS background, we present here a new exact solution, in this class, to the quadratic gravity in D dimensions which repr...
New constructions of entanglement-assisted quantum codes
Allahmadi, A.; AlKenani, A.; Hijazi, R.; Muthana, N.; Özbudak, Ferruh; Solé, P. (2021-01-01)
We present two new constructions of entanglement-assisted quantum error-correcting codes using some fundamental properties of (classical) linear codes in an effective way. The main ideas include linear complementary dual codes and related concatenation constructions. Numerical examples in modest lengths show that our constructions perform better than known constructions in the literature. We also give a proof on a generalization of binary Singleton type bound on entanglement-assisted quantum error-correctin...
New Positive Solutions of Nonlinear Elliptic PDEs

We are concerned with positive solutions of two types of nonlinear elliptic boundary value problems (BVPs). We present conditions for existence, uniqueness and multiple positive solutions of a first type of elliptic BVPs. For a second type of elliptic BVPs, we obtain conditions for existence and uniqueness of positive global solutions. We employ mathematical tools including strictly upper (SU) and strictly lower (SL) solutions, iterative sequence method and Amann theorem. We present our research findings in...
