Quadrature-Symmetric PulsePol for Robust Quantum Control Beyond the Ideal Pulse Approximation
Mayur Jhamnani, Venkata SubbaRao Redrouthu, Jose P. Carvalho +6
PulsePol is an elegantly designed pulse-sequence-based quantum control scheme that enables polarization transfer between electron and nuclear spins, for example, in nitrogen-vacanc…
In situ Learning-Based Spin Engineering of Pulsed Dynamic Nuclear Polarization
Filip V. Jensen, José P. Carvalho, Nino Wili +6
Pulsed Dynamic Nuclear Polarization (DNP) is currently receiving substantial interest as a means to enhance the sensitivity of nuclear magnetic resonance (NMR) and magnetic resonan…
Extending numerical simulations in SIMPSON: Electron paramagnetic resonance, dynamic nuclear polarisation, propagator splitting, pulse transients, and quadrupolar cross terms
David L. Goodwin, Jose P. Carvalho, Anders B. Nielsen +4
Aimed at the simulation, design, and interpretation of advanced pulse experiments crossing the boundaries between nuclear magnetic resonance (NMR) and electron paramagnetic resonan…
Longitudinal Pulsed Dynamic Nuclear Polarization Transfer via Periodic Optimal Control
José P. Carvalho, Anders Bodholt Nielsen, David L. Goodwin +2
Taking inspiration from NMR spectroscopy, periodic irradiation schemes have recently shown remarkable performance when implemented into pulsed dynamic nuclear polarization (DNP) se…
Controlling Effective Hamiltonians: Broadband Pulsed Dynamic Nuclear Polarization by Constrained Random Walk and Non-linear Optimization
Anders B. Nielsen, Jose P. Carvalho, Nino Wili +5
We present constrained random walk (cRW) and figure of merit (FOM) based non-linear optimization procedures for systematic design and fundamental understanding of magnetic resonanc…
Bridging DNP and MAS NMR dipolar recoupling -- from static single crystal to spinning powders
Jose P. Carvalho, Anders Bodholt Nielsen, Eniko Baligacs +2
Spin engineering of advanced pulse sequences has had a transformative impact on the development of nuclear magnetic resonance (NMR) spectroscopy, to an extending degree also electr…
