Dynamics of Majorana tetron qubits under quasiparticle poisoning
Sauri Bhattacharyya, Bernard van Heck
We study the dissipative dynamics of a Majorana tetron qubit in the presence of extrinsic quasiparticle poisoning due to the coupling to external leads. From the Bloch-Redfield equ…

Decoherence of Majorana zero modes mediated by gapless fermions
Sauri Bhattacharyya, Marco Grilli, Bernard van Heck
We study the decoherence of a collection of Majorana zero modes weakly coupled to a gapless reservoir of non-interacting fermions. Using the Born-Markov approximation, we derive a…

Quantum Transport Theory of Strongly Correlated Matter
Assa Auerbach, Sauri Bhattacharyya
This report reviews recent progress in computing Kubo formulas for general interacting Hamiltonians. The aim is to calculate electric and thermal magneto-conductivities in strong s…
