Trilinos: Enabling Scientific Computing Across Diverse Hardware Architectures at Scale
Matthias Mayr, Alexander Heinlein, Christian Glusa +30
Trilinos is a community-developed, open-source software framework that facilitates building large-scale, complex, multiscale, multiphysics simulation code bases for scientific and…
Envelopes of the Thurston metric on Teichmüller space
Huiping Pan, Michael Wolf
For the Thurston (asymmetric) metric on Teichmüller space, the defect from being uniquely geodesic is described by the envelope, defined as the union of geodesics from the initial…
Gibbs state postulate from dynamical stability -- Redundancy of the zeroth law
Vjosa Blakaj, Matthias C. Caro, Anouar Kouraich +2
Gibbs states play a central role in quantum statistical mechanics as the standard description of thermal equilibrium. Traditionally, their use is justified either by a heuristic, a…
Partial trace relations beyond normal matrices
Pablo Costa Rico, Michael M. Wolf
We investigate the relationship between partial traces and their dilations for general complex matrices, focusing on two main aspects: the existence of (joint) dilations and norm i…
Quantum tomography from the evolution of a single expectation
Hjalmar Rall, Michael M. Wolf
We investigate the possibility of performing full quantum tomography based on the homogeneous time evolution of a single expectation value. Remarkably, every non-trivial binary mea…
