Solid-State NMR Dipolar Recoupling in Presence of Large Chemical Shielding Anisotropies by Quaternion-Based Effective Hamiltonian Optimal Control
Enikő Baligács, Nino Wili, José P. Carvalho +2
Dipolar recoupling is a key element in magic-angle-spinning (MAS) solid-state NMR spectroscopy with reintroduced dipole-dipole coupling interactions providing information about int…
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…
Characterization of Strongly Hyperfine-split Protons by DNP
Gian-Marco Camenisch, Nino Wili, Gunnar Jeschke +1
Dynamic nuclear polarization experiments use microwave irradiation to transfer the larger electron polarization to nuclear spins of interest, and thus enhance the NMR transitions a…
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…
Observation of Dynamic Nuclear Polarization Echoes
Nino Wili, Anders B. Nielsen, José P. Carvalho +1
It is demonstrated that the time evolution of the electron-nuclear polarization transfer process during pulsed dynamic nuclear polarization (DNP) can be reversed on a microsecond t…
Emergence of highly coherent quantum subsystems of a noisy and dense spin system
A. Beckert, M. Grimm, N. Wili +6
Quantum sensors and qubits are usually two-level systems (TLS), the quantum analogs of classical bits which assume binary values '0' or '1'. They are useful to the extent to which…
Symmetry-Based Singlet-Triplet Excitation in Solution Nuclear Magnetic Resonance
Mohamed Sabba, Nino Wili, Christian Bengs +2
Coupled pairs of spin-1/2 nuclei support one singlet state and three triplet states. In many circumstances the nuclear singlet order, defined as the difference between the singlet…
Designing broadband pulsed dynamic nuclear polarization sequences in static solids
Nino Wili, Anders Bodholt Nielsen, Laura Alicia Voelker +4
Dynamic nuclear polarization (DNP) is an NMR hyperpolarization technique that mediates polarization transfer from highly polarized unpaired electrons to NMR-active nuclei via micro…
