Fault Tolerant Quantum Phases of Matter
Colin V. Coane, Shouzhen Gu, Aleksander Kubica
We introduce a classification of quantum phases of mixed states based on the ability to preserve and fault tolerantly transfer information. We formulate phase equivalence between s…

Supersymmetry of dissipative Bose-Fermi systems with application to Jaynes-Cummings and Dicke models
Colin V. Coane, Francesco Iachello
We demonstrate how supersymmetries of Hamiltonians for coupled Bose-Fermi systems can be used to place the Hamiltonians of the Jaynes-Cummings model and Dicke model under the rotat…
