Simulating alternating bias assisted annealing of amorphous oxide tunnel junctions
Alexander C. Tyner, Alexander V. Balatsky
Amorphous oxide tunneling barriers, primarily formed from aluminum, represent one of the most widely adopted platforms for superconducting quantum bits (qubits). To overcome challe…
Machine learning assisted high throughput prediction of moiré materials
Daniel Kaplan, Alexander C. Tyner, Eva Y. Andrei +1
The world of 2D materials is rapidly expanding with new discoveries of stackable and twistable layered systems composed of lattices of different symmetries, orbital character, and…
Tailoring Superconductivity with Two-Level Systems
Joshuah T. Heath, Alexander C. Tyner, S. Pamir Alpay +2
We investigate the impact of two-level systems (TLSs) on superconductivity, treating them as soft modes localised in real space. We show that these defects can either enhance or su…
Accelerated characterization of two-level systems in superconducting qubits via machine learning
Avinash Pathapati, Olli Mansikkamäki, Alexander Tyner +1
We introduce a data-driven approach for extracting two-level system (TLS) parameters-frequency , coupling strength , dissipation time , and the pure dephasi…
Accelerated Discovery of Topological Conductors for Nanoscale Interconnects
Alexander C. Tyner, William Rogers, Po-Hsin Shih +5
The sharp increase in resistivity of copper interconnects at ultra-scaled dimensions threatens the continued miniaturization of integrated circuits. Topological semimetals (TSMs) w…
Two-dimensional Disordered Projected Branes: Stability and Quantum Criticality via Dimensional Reduction
Alexander C. Tyner, Vladimir Juricic, Bitan Roy
The interplay of disorder and dimensionality governs the emergence and stability of electronic phases in quantum materials and quantum phase transitions among them. While three-dim…
Fine tuning generative adversarial networks with universal force fields: application to two-dimensional topological insulators
Alexander C. Tyner
Despite rapid growth in use cases for generative artificial intelligence, its ability to design purpose built crystalline materials remains in a nascent phase. At the moment invers…
Many-body effects of two-level systems in superconducting qubits
Joshuah T. Heath, Alexander C. Tyner, Thue Christian Thann +4
Superconducting qubits are often adversely affected by two-level systems (TLSs) within the Josephson junction, which contribute to decoherence and subsequently limit the performanc…
Evidence for topological origin of large spin-shift current in antiferromagnetic TiC
Ali Sufyan, Hasan M. Abdullah, J. Andreas Larsson +1
The shift current is a non-linear photocurrent generally associated with the underlying quantum geometry. However, a topological origin for the shift photocurrent in non-centrosymm…
Identification of soft modes in amorphous AlO via first-principles
Alexander C. Tyner, Joshuah T. Heath, Thue Christian Thann +4
Amorphous AlO is a fundamental component of modern superconducting qubits. While amphorphous oxides offer distinct advantages, such as directional isotropy and a consis…
Separate surface and bulk topological Anderson localization transitions in disordered axion insulators
Cormac Grindall, Alexander C. Tyner, Ang-Kun Wu +2
In topological phases of matter for which the bulk and boundary support distinct electronic gaps, there exists the possibility of decoupled mobility gaps in the presence of disorde…
