Annals of Physics Classical impurities and boundary Majorana zero
... For h ! 0 one finds two decoupled boundary MZMs, c1 and c2N , in the otherwise dimerized chain, implying a two-fold degeneracy of the ground state, while for J ! 0 the KM lattice has a full dimer covering and the ground state is unique. At finite h/J < 1 the exact degeneracy between the two boundary ...

Quantum Information with Optical Continuous Variables - QuIC
... The dissertation starts with an historical introduction to quantum mechanics, its paradoxes and the new field of quatum information theory. The Introduction situates historically both subjects of my thesis: the Bell tests and quantum key distribution. The rest of the thesis is divided in two parts. ...

Entanglement in periodically driven quantum systems
... Schrödinger’s quote in the above epigraph, this aspect of quantum mechanics represents the “entire departure from classical lines of thought”. For a long time, it remained undecided whether entanglement is indeed an observable property of nature or just an artifact of our (insufficient) description ...

I’d also like to thank Chris and Gretchen Ekstrom, who kindly invited me into their family (and let me watch Simpson’s videos!) which made me feel more at home than I would have thought possible. The PhD is the last vestige of the apprenticeship system: nowhere else can one find such a clos ...

Monte Carlo Studies of Ising Spin Glasses and Random Field Systems

The latter either changes the chemical composition of compounds and alloys (via dilution or mixing) or it decrystallizes the pure material (via sputte ...
