Implementing Josephson Junction spectroscopy in a scanning tunneling microscope
Margaret A. Fortman, David C. Harrison, Ramiro H. Rodriguez +6
Josephson junction spectroscopy is a powerful local microwave spectroscopy technique that has promising potential as a diagnostic tool to probe the microscopic origins of noise in…
Quasiparticle Poisoning of Superconducting Qubits from Resonant Absorption of Pair-breaking Photons
Chuan-Hong Liu, David C. Harrison, Shravan Patel +8
The ideal superconductor provides a pristine environment for the delicate states of a quantum computer: because there is an energy gap to excitations, there are no spurious modes w…
Using low moments of the Liouvillian to calculate mode lifetimes in low dimensional models
Yang Gao, Doyl Dickel, David Harrison +1
A recent proposal for practical calculation of vibrational mode lifetimes is tested on simple, low-dimensional anharmonic models. The proposed scheme approximates the mode lifetime…
Improved Calculation of Vibrational Mode Lifetimes in Anharmonic Solids - Part II: Numerical Results
Doyl Dickel, Murray S. Daw
In a two-part publication, we propose and analyze a formal foundation for practical calculations of vibrational mode lifetimes in solids. The approach is based on a recursion metho…
