Research

I am currently a doctorant in Prof. Y. Gefen group. My main research interests are:

Weak Values in Condensed Matter Physics

Charge sensing via Weak Values amplification

My main research topic is to find implementations of the Weak Value protocol in condensed matter systems. We study systems such as AB-interferometers, Mach-Zehnder interferometers in the fractional quantum Hall Regime, and superconducting phase qubits.

Topological phases of quasicrystals

Pumping experiment

I co-founded a student collaboration in order to study the topological phases of quasicrystals. We have managed, thus far, to prove that quasicrystals possess a topological classification that is usually existing in dimensions higher than their own. We verify our analysis using a photonic quasi-lattice experiment.

Quantum Computation

Spin exchange

I have written my Master thesis in Prof. D. Loss group. My research topic was the study of multi-particle qubits. We defined a mathematical language that enabled us to categorize physical systems as possible candidates for quantum computation. The work can be viewed as a pdf.

Some of the results were published in
Controlled-NOT for multiparticle qubits and topological quantum computation based on parity measurements, OZ, B. Braunecker, and D. Loss, Phys. Rev. A 77, 012327 (2008), [arXiv:0708.1062] which was listed in Virtual J. of Nanotech. 17(5) (2008) and Virtual J. on Quant. Inf. 8(2),(2008).

The results were also presented at the FNST2008 conference as a poster.

Experimental Molecular Electronics

Break junction sample

I have made a project work in the group of Prof. C. Schönenberger. In this project I have studied the "Gold-atoms motion on mechanically controllable break junctions contacts". The work can be viewed as a pdf.

Computational Physics

BigDFT project

I have worked as part of the BIGDFT project in Prof. S. Goedecker group. My work included code parallelization and optimization, and diagonalization algorithm implementation.
