Boundary-induced topological transition in an open SSH model
Alexei Bissonnette, Nicolas Delnour, Andrew Mckenna +3
We consider a Su-Schrieffer-Heeger chain to which we attach a semi-infinite undimerized chain (lead) to both ends. We study the effect of the openness of the SSH model on its prope…
Scanning qubit probe of edge states in a topological insulator
Nicolas Delnour, Alexei Bissonnette, Hichem Eleuch +2
In this work, we propose a novel qubit-based sensor with the ability to characterize topological edge states in low-dimensional systems. A composite system is studied, consisting o…
What is the Gravitational Field of a Mass in a Spatially Nonlocal Quantum Superposition?
Rémi Ligez, R. B. MacKenzie, Victor Massart +2
The study of the gravitational field produced by a spatially non-local, superposed quantum state of a massive particle is a thrilling area of modern physics. One question to be ans…
Universal quantum computation with symmetric qubit clusters coupled to an environment
Christian Boudreault, Hichem Eleuch, Michael Hilke +1
One of the most challenging problems for the realization of a scalable quantum computer is to design a physical device that keeps the error rate for each quantum processing operati…
Ferromagnetic instability in PAAI in the sky
R. B. MacKenzie, M. B. Paranjape, U. A. Yajnik
We study an idealised plasma of fermions, coupled through an abelian gauge force , and which is asymmetric in that the masses of the oppositely charged species are greatly…
Gravitons in the Strong-Coupling Regime
Jorge Gamboa, Richard MacKenzie, Fernando Méndez
In the context of gravity in the strong-coupling regime, the propagation amplitude of gravity coupled to relativistic particles undergoing geodesic separation is calculated exactly…
