Theoretical Framework Of Exchange Coupled Tripartite Spin Systems With Magnetic Anisotropy And Predictions Of Spin And Electronic Transport Properties For Their Use In Quantum Architectures, Eric Switzer

Electronic Theses and Dissertations, 2020-2023

There has been significant interest in spin systems involving two or more coupled spins as a single logical qubit, particularly for scalable quantum computing architectures. Recent realizations include the so-called singlet-triplet qubits and coupled magnetic molecules. An important class of coupled-spin systems, the three-spin paradigm for spin greater than 1/2, has not yet been fully realized in scalable qubit architectures. In this thesis, I develop the theoretical framework to investigate a class of tripartite spin models for realistic systems. First, I model a spin 1/2 particle (e.g., an electron) and two spin 1 particles (in a dimer arrangement) coupled with …

Amazonian Wetland Domestication: A Spatial Analysis Of Pre-Columbian Fish Weirs In Lowland Bolivia, Charlotte Robinson

Electronic Theses and Dissertations, 2020-2023

Recent archaeological studies show that pre-Columbian communities began modifying Southwestern Amazonia approximately 3,500 years ago. In lowland Bolivia, a recently mapped network of fish weirs in West Central Llanos de Mojos (WCM) demonstrates how ancient Mojeño groups built artificial earthworks to harness seasonal flooding and catch fish. In the eastern region of Baures, a similar complex of fish weirs has been studied since the 1990s, generating questions about how this system may function in a different hydrological and anthropogenic setting. Similarly, previous research within WCM has focused on the fields and forest islands that pre-Columbian populations built to elevate themselves …
