This thesis covers three experiments with cold and ultracold (Bose-Einstein condensate based) alkali 87Rb gases for quantum simulation. In the first experiment, we quantum simulate Abelian and non-Abelian gauge fields in the parameter space of a four-level quantum system. Then, …
High-temperature composite materials have broad applications in the energy and transportation sectors because of their unique capabilities to sustain strength at elevated temperatures, inert interaction with some coolants, and their high strength-to-weight ratio. These encompass…
Quantum degenerate gases have proven to be an ideal platform for the simulation of complex quantum systems. Due to their high level of control it is possible to readily design and implement systems with effective Hamiltonians in the laboratory. This thesis presents new tools for…
Due to the variety of tools available to control atomic, molecular, and optical (AMO) systems, they provide a versatile platform for studying many-body physics, quantum simulation, and quantum computation. Although extensive efforts are employed to reduce coupling between the sy…
Rydberg ensembles, atomic clouds with one or more atoms excited to a Rydberg state, have proven to be a good platform for the study of photon-photon interactions. This is due to the nonlinearities they exhibit at the single photon level arising from Rydberg-Rydberg interactions.…
The construction and modifications of highly active, stable and low cost electrocatalysts promoting the oxygen and hydrogen evolution reactions (OER and HER) in water splitting are the key areas of research in energy generation and conversion. Given the significance of the HER a…
Düşük sıcaklıkta oyuk katodlu plazma destekli atomik tabaka biriktirme (HCPA-ALD) tarafından büyütülen grup III-Nitrit ince filmlerin özellikleri, biriken ince filmler için detaylı karakterizasyon sonuçlarıyla sunulmaktadır. Bu bağlamda, önce, film kalınlığı ve substratın düşük …
We describe several experiments performed on a two species apparatus capable of producing Bose-Einstein condensates (BECs) of rubidium 87 and degenerate Fermi gases (DFGs) of potassium 40. We first describe computational results for observed optical depths with absorption imagin…
Increasing the number of qubits that can be controlled in a quantum system represents an essential challenge to the field of quantum computing. Quantum networks consisting of nodes for local information processing and photonic channels to distribute entanglement between differen…
Scaling up controlled quantum systems to involve large numbers of qubits remains one of the outstanding challenges of quantum information science. One path toward scalability is the use of a modular architecture where adjacent qubits may be entangled with applied electromagnetic…
A large-scale quantum computer will have the ability to solve many computational problems beyond the capabilities of today's most powerful computers. Significant efforts to build such a computer are underway, many of which are small prototypes that are believed to be extensible …
