Presence versus absence of Two-Dimensional Fermi Surface Anomalies
Donovan Buterakos, DinhDuy Vu, Jiabin Yu +1
We theoretically consider Fermi surface anomalies manifesting in the temperature dependent quasiparticle properties of two-dimensional (2D) interacting electron systems, comparing…
Exact analytical treatment of multiqubit noisy dynamics in exchange-coupled semiconductor spin qubits
Donovan Buterakos, Sankar Das Sarma
Charge noise remains the primary obstacle to the development of quantum information technologies with semiconductor spin qubits. We use an exact analytical calculation to determine…
Geometrical Formalism for Dynamically Corrected Gates in Multiqubit Systems
Donovan Buterakos, Sankar Das Sarma, Edwin Barnes
The ability to perform gates in multiqubit systems that are robust to noise is of crucial importance for the advancement of quantum information technologies. However, finding contr…
The two-dimensional electron self-energy: Long-range Coulomb interaction
Yunxiang Liao, Donovan Buterakos, Mike Schecter +1
The electron self-energy for long-range Coulomb interactions plays a crucial role in understanding the many-body physics of interacting electron systems (e.g. in metals and semicon…
Coupled electron-impurity and electron-phonon systems as trivial non-Fermi liquids
Donovan Buterakos, Sankar Das Sarma
We consider an electron gas, both in two (2D) and three (3D) dimensions, interacting with quenched impurities and phonons within leading order finite-temperature many body perturba…
Ferromagnetism in Quantum Dot Plaquettes
Donovan Buterakos, Sankar Das Sarma
Following the recent claimed obsevation of Nagaoka ferromagnetism in finite size quantum dot plaquettes, a general theoretical analysis is warranted in order to ascertain in rather…
