At tremendous low temperatures, clouds of bosonic atoms shape what's often called a Bose-Einstein condensate. lately, it has develop into transparent that many differing types of condensates  -- so referred to as fragmented condensates -- exist. so that it will inform even if fragmentation happens or now not, it can be crucial to unravel the complete many-body Schrödinger equation, a role that remained elusive for experimentally suitable stipulations for a few years. during this thesis the 1st numerically detailed recommendations of the time-dependent many-body Schrödinger equation for a bosonic Josephson junction are supplied and in comparison to the approximate Gross-Pitaevskii and Bose-Hubbard theories. it really is thereby proven that the dynamics of  Bose-Einstein condensates is much extra difficult than one could expect according to those approximations. a distinct conceptual innovation during this thesis are optimum lattice types. it truly is proven how all quantum lattice types of condensed topic physics which are in response to Wannier capabilities, e.g. the  Bose/Fermi Hubbard version, may be optimized variationally. This ends up in fascinating new physics.

with a purpose to probe the photons, we ship around the hollow space a unique form of Rydberg atoms, known as ''circular'', within which the outer electron orbits on a circle of enormous diameter, a few thousand occasions higher than a standard flooring kingdom atom. those excited Rubidium atoms are ready with lasers and radio-frequency excitation, utilizing a transformed model of a strategy invented through Daniel Kleppner and Randy Hulet at MIT 1983. in accordance with quantum concept, the orbiting Rydberg electron can also be a wave, that has a de Broglie wavelength, and the of a strong orbit is that there's an integer variety of those wavelengths alongside the circumference. This quantity, known as the valuable quantum variety of the Rydberg atom.
In the e and g Rydberg states, the circulating de Broglie wave has a uniform amplitude, leading to an electron cost density established on the atomic nucleus, yielding a 0 electrical atomic dipole. that allows you to organize an electrical dipole, a pulse of resonant microwave might be utilized to the atom, bringing it in a superposition of the 2 adjoining e and g states, with respectively fifty one and 50 nodes of their wave functionality. This superposition of states may be often called a “Schrödinger cat” since it implies an atom whilst in degrees. the 2 de Broglie waves making up the cat intrude constructively at one finish of the orbit and destructively on the different finish, leading to a web electrical dipole, rotating within the orbital airplane at fifty one GHz. This dipole behaves as a rotating antenna super delicate to microwave radiation. it will possibly even be defined because the rotating hand of a clock, ticking at fifty one GHz. while microwave radiation, non-resonant with the transition among the 2 states e and g, impinges at the atom, it can't soak up it and therefore the photons stay intact, making sure the non-demolition personality necessary to our experiments. even if, the influence of this non-resonant mild is to shift the atomic power degrees a little bit and as a result modify the rotating frequency of the atomic dipole, our clock hand. This mild shift impact have been came across in 1961 via Claude Cohen-Tannoudji in his seminal optical pumping reviews. mild shifts are proportional to the sector strength, i.e. to the photon quantity.
Being inversely proportional to the atom-cavity box detuning, they are often maximized via tuning the hollow space shut adequate to resonance yet a ways sufficient to prevent any photon absorption or emission approach. in relation to Rydberg atoms, the impact is then very huge, leading to a section shift of the atomic dipole after the atom leaves the hollow space that may achieve the price of a hundred and eighty grad, the dipole leaping in contrary instructions while the photon quantity adjustments by means of one unit. Measuring this part shift quantities to counting the photon quantity with no destroying the sunshine quanta.
To realize those shifts we outfitted an atomic interferometer round our photon storing hollow space. The atoms, ready within the round nation e within the field O, go the hollow space C one after the other sooner than being detected by way of box ionization in D. necessary to the test, auxiliary microwave zones R1 and R2 are sandwiching the hollow space C. within the first one, the atoms are ready within the kingdom superposition of e and g, a Schrödinger cat country. This strategy quantities to beginning a stopwatch, giving to the atomic dipole, i.e. to the clock hand, its preliminary course. The atomic dipole then rotates because the atom crosses the hollow space, until eventually a moment microwave flash, utilized in R2, is used to become aware of the course of the atomic dipole at hollow space go out, hence measuring the section accumulation of the clock. the combo of the 2 separated microwave resonators R1 and R2 is really a Ramsey interferometer. The gadget were invented in 1949 through Norman Ramsey.
