New quantum spin states induced by magnetic frustration on the kagome lattice
Magnetic frustration helps destabilizing conventional Néel order at T = 0 in dimensions 2, and therefore allows the emergence of new original quantum phases. The S=1/2... -
Type Indeterminacy: A Model for the KT(Kahneman-Tversky)-Man
In this paper, we propose to use elements of the mathematical formalism of Quantum Mechanics to capture the idea that agents' preferences, in addition to being... -
Rank penalized estimation of a quantum system
We introduce a new method to reconstruct the density matrix $\rho$ of a system of $n$-qubits and estimate its rank $d$ from data obtained by quantum state tomography...
