Half-integer charge injection by a Josephson junction without excess noise
F. Hassler, A. Grabsch, M. J. Pacholski +4
A Josephson junction in a topological superconductor can inject a charge e/2 into a normal-metal contact, carried by chiral Majorana edge modes. Here we address the question whethe…
Localization landscape for Dirac fermions
G. Lemut, M. J. Pacholski, O. Ovdat +3
In the theory of Anderson localization, a landscape function predicts where wave functions localize in a disordered medium, without requiring the solution of an eigenvalue problem.…
The breaking of continuous scale invariance to discrete scale invariance: a universal quantum phase transition
Omrie Ovdat, Eric Akkermans
We provide a review on the physics associated with phase transitions in which continuous scale invariance is broken into discrete scale invariance. The rich features of this transi…
Vacancies in Graphene : Dirac Physics and Fractional Vacuum Charges
Omrie Ovdat, Yaroslav Don, Eric Akkermans
The study of vacancies in graphene is a topic of growing interest. A single vacancy induces a localized stable charge of order unity interacting with other charges of the conductor…
On the landscape of scale invariance in quantum mechanics
Daniel K. Brattan, Omrie Ovdat, Eric Akkermans
We consider the most general scale invariant radial Hamiltonian allowing for anisotropic scaling between space and time. We formulate a renormalisation group analysis of this syste…
