Emergent gravity from the correlation of spin- systems coupled with a scalar field
Quentin Ansel
This paper introduces several ideas of emergent gravity, which come from a system similar to an ensemble of quantum spin- particles. To derive a physically relevant t…

A Model of Spinfoam Coupled with an Environment
Quentin Ansel
In this paper, an open quantum system theory for spinfoams is developed. This new formalism aims at deriving an effective Lindblad equation to compute the reduced dynamics of a qua…

Selective and Robust Time-Optimal Rotations of Spin Systems
Quentin Ansel, Steffen J. Glaser, Dominique Sugny
We study the selective and robust time-optimal rotation control of several spin-1/2 particles with different offset terms. For that purpose, the Pontryagin Maximum Principle is app…
