Winding Numbers and Topology of Aperiodic Tilings
Yaroslav Don, Eric Akkermans
We show that diffraction features of quasicrystals can be retrieved from a single topological quantity, the Čech cohomology group, , which enco…
Quantum tomography of entangled spin-multi-photon states
Dan Cogan, Giora Peniakov, Oded Kenneth +2
We present a novel method for quantum tomography of multi-qubit states. We apply the method to spin-multi-photon states, which we produce by periodic excitation of a semiconductor…
Relating Diffraction and Spectral Data of Aperiodic Tilings: Towards a Bloch theorem
Eric Akkermans, Yaroslav Don, Jonathan Rosenberg +1
The purpose of this paper is to show the relationship in all dimensions between the structural (diffraction pattern) aspect of tilings (described by Čech cohomology of the tiling s…
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-demand source of maximally entangled photon-pairs using the biexciton-exciton radiative cascade
R. Winik, D. Cogan, Y. Don +7
We perform full time resolved tomographic measurements of the polarization state of pairs of photons emitted during the radiative cascade of the confined biexciton in a semiconduct…
Numerical Study of Continuous and Discontinuous Dynamical Phase Transitions for Boundary Driven Systems
Ohad Shpielberg, Yaroslav Don, Eric Akkermans
The existence and search for thermodynamic phase transitions is of unfading interest. In this paper, we present numerical evidence of dynamical phase transitions occurring in bound…
