The structures of state space concerning quantum dynamical semigroups

B Baumgartner, H Narnhofer - Reviews in Mathematical Physics, 2012 - World Scientific
Each semigroup describing time evolution of an open quantum system on a finite dimensional
Hilbert space is related to a special structure of this space. It is shown how the space can …

State space for two qutrits has a phase space structure in its core

B Baumgartner, BC Hiesmayr, H Narnhofer - Physical Review A—Atomic …, 2006 - APS
We investigate the state space of bipartite qutrits. For states which are locally maximally mixed
we obtain an analog of the “magic” tetrahedron for bipartite qubits—a magic simplex W . …

Analysis of quantum semigroups with GKS–Lindblad generators: II. General

B Baumgartner, H Narnhofer - Journal of Physics A: Mathematical …, 2008 - iopscience.iop.org
Semigroups describing the time evolution of open quantum systems in finite-dimensional
spaces have generators of a special form, known as Lindblad generators. These generators …

Mitofusin-2 determines mitochondrial network architecture and mitochondrial metabolism: a novel regulatory mechanism altered in obesity

…, S Pich, FX Soriano, N Vega, B Baumgartner… - Journal of Biological …, 2003 - ASBMB
In many cells and specially in muscle, mitochondria form elongated filaments or a branched
reticulum. We show that Mfn2 (mitofusin 2), a mitochondrial membrane protein that …

Multicomponent new particle formation from sulfuric acid, ammonia, and biogenic vapors

…, A Amorim, A Baccarini, PS Bauer, B Baumgartner… - Science …, 2018 - science.org
A major fraction of atmospheric aerosol particles, which affect both air quality and climate,
form from gaseous precursors in the atmosphere. Highly oxygenated organic molecules (…

Rapid growth of organic aerosol nanoparticles over a wide tropospheric temperature range

…, PS Bauer, B Baumgartner… - Proceedings of the …, 2018 - National Acad Sciences
Nucleation and growth of aerosol particles from atmospheric vapors constitutes a major
source of global cloud condensation nuclei (CCN). The fraction of newly formed particles that …

A special simplex in the state space for entangled qudits

B Baumgartner, B Hiesmayr… - Journal of Physics A …, 2007 - iopscience.iop.org
The focus is on two parties with Hilbert spaces of dimension d, ie'qudits'. In the state space
of these two possibly entangled qudits an analogue to the well-known tetrahedron with the …

[HTML][HTML] Molecular understanding of the suppression of new-particle formation by isoprene

…, A Baccarini, PS Bauer, B Baumgartner… - Atmospheric …, 2020 - acp.copernicus.org
Nucleation of atmospheric vapours produces more than half of global cloud condensation
nuclei and so has an important influence on climate. Recent studies show that monoterpene ( …

Photo-oxidation of aromatic hydrocarbons produces low-volatility organic compounds

…, A Amorim, A Baccarini, B Baumgartner… - … science & technology, 2020 - ACS Publications
To better understand the role of aromatic hydrocarbons in new-particle formation, we measured
the particle-phase abundance and volatility of oxidation products following the reaction …

Are consumers heterogeneous in their preferences for odd and even prices? Findings from a choice-based conjoint study

B Baumgartner, WJ Steiner - International Journal of Research in …, 2007 - Elsevier
While marketing theories provide some justification for the common practice of setting 9-ending
prices, the results of empirical studies are not conclusive on the effects of odd pricing. …
