Theory of ab initio downfolding with arbitrary range electron-phonon coupling

Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Norm M. Tubman, Christopher J. N. Coveney, Chih-En Hsu, Andres Montoya-Castillo, Marina R. Filip | Summary: Ab initio downfolding describes the electronic structure of materials within a low-energy subspace, often around the Fermi level. Typically starting from mean-field calculations, this framework allows for the calculation of […]

Optical Readout of Coherent Nuclear Spins Beyond the NV Center Electron T$_1$

Kavli Affiliate: Gregory D. Fuchs | First 5 Authors: Johnathan Kuan, Gregory D. Fuchs, , , | Summary: The nitrogen-vacancy (NV) center is an emerging platform for constructing inertial sensors. Its native nitrogen spin can serve as a gyroscope using Ramsey interferometry protocols. The sensitivities of these nuclear-spin-based NV gyroscopes are limited by the phase […]

Reactive path ensembles within nonequilibrium steady-states

Kavli Affiliate: David T. Limmer | First 5 Authors: Aditya N. Singh, David T. Limmer, , , | Summary: The modern theory of rare events is grounded in near equilibrium ideas, however many systems of modern interest are sufficiently far from equilibrium that traditional approaches do not apply. Using the recently developed variational path sampling […]

Observation of Photon Blockade in a Tavis-Cummings System

Kavli Affiliate: Irfan Siddiqi | First 5 Authors: Brian Marinelli, Alex H. Rubin, Victoria A. Norman, Santai Yang, Ravi Naik | Summary: We observe blockade of microwave photons in a Tavis-Cummings system comprising a superconducting cavity and up to $N=3$ transmon qubits. The effect is characterized with photon number-resolving spectroscopy using an additional dispersively coupled […]
