Open quantum system violates generalized Pauli constraints on quantum device

I Avdic, LAM Sager-Smith, DA Mazziotti - Communications Physics, 2023 - nature.com
The Pauli exclusion principle governs the fundamental structure and function of fermionic
systems from molecules to materials. Nonetheless, when such a fermionic system is in a …

Quantum phase transitions in a model Hamiltonian exhibiting entangled simultaneous fermion-pair and exciton condensations

S Warren, LAM Sager-Smith, DA Mazziotti - Physical Review B, 2022 - APS
Quantum states of a novel Bose-Einstein condensate, in which both fermion-pair and exciton
condensations are simultaneously present, have recently been realized theoretically in a …

[HTML][HTML] Magnetic phases of spatially modulated spin-1 chains in Rydberg excitons: Classical and quantum simulations

M Sajjan, H Alaeian, S Kais - The Journal of Chemical Physics, 2022 - pubs.aip.org
In this work, we study the magnetic phases of a spatially modulated chain of spin-1 Rydberg
excitons. Using the Density Matrix Renormalization Group (DMRG) technique, we study …

Topological phase transitions captured in the set of reduced density matrices

S Warren, LAM Sager-Smith, DA Mazziotti - Physical Review B, 2024 - APS
Topological phase transitions fall outside of the symmetry-breaking paradigm and therefore
elude many traditional analytical methods. In particular, significant geometric features found …

Dimensionality in dipolar quantum systems

SA Meynell - 2023 - escholarship.org
Engineered quantum systems are a powerful tool for quantum sensing and simulating
otherwise intractable many-body quantum systems. Defects in the solid-state have emerged …

Exploration of Highly-Correlated Systems on Classical and Quantum Devices

LAM Sager-Smith - 2023 - search.proquest.com
Elucidation of many chemical behaviors and properties depends on our ability to model the
