Mechanical rotation via optical pumping of paramagnetic impurities

Pablo R. Zangara, Alexander Wood, Marcus W. Doherty +1

Hybrid quantum systems exhibiting coupled optical, spin, and mechanical degrees of freedom can serve as a platform for sensing, or as a bus to mediate interactions between qubits w…

13C dynamic nuclear polarization in diamond via a microwave-free 'integrated' cross effect

J. Henshaw, D. Pagliero, P. R. Zangara +6

Color-center-hosting semiconductors are emerging as promising source materials for low-field dynamic nuclear polarization (DNP) at or near room temperature, but hyperfine broadenin…

The Momentum Representation of the Hydrogen Atom in Paraboloidal Coordinates

John R. Lombardi

We examine the procedure to construct the variables of use for the momentum representation in quantum mechanics. The momentum variables must be chosen properly conjugate to the cor…

Two-electron-spin ratchets as a platform for microwave-free dynamic nuclear polarization of arbitrary material targets

Pablo R. Zangara, Jacob Henshaw, Daniela Pagliero +4

Optically-pumped color centers in semiconductor powders can potentially induce high levels of nuclear spin polarization in surrounding solids or fluids at or near ambient condition…

Complexity of full counting statistics of free quantum particles in product states

Dmitri A. Ivanov, Leonid Gurvits

We study the computational complexity of quantum-mechanical expectation values of single-particle operators in bosonic and fermionic multi-particle product states. Such expectation…

Hyperpolarized relaxometry based nuclear T1 noise spectroscopy in hybrid diamond quantum registers

Ashok Ajoy, Ben Safvati, Raffi Nazaryan +14

Understanding the origins of spin lifetimes in hybrid quantum systems is a matter of current importance in several areas of quantum information and sensing. Methods that spectrally…

Proper time in atom interferometers: Diffractive versus specular mirrors

Enno Giese, Alexander Friedrich, Fabio Di Pumpo +4

We compare a conventional Mach-Zehnder light-pulse atom interferometer based on diffractive mirrors with one that uses specular reflection. In contrast to diffractive mirrors that…
