Microscopic control of Si nuclear spins near phosphorus donors in silicon
J. Järvinen, D. Zvezdov, J. Ahokas +11
We demonstrate an efficient control of Si nuclear spin orientation for specific lattice sites near P donors in silicon crystals at temperatures below 1 K and in high…
Tolerances induced by irredundant coverings
Jouni Järvinen, Sándor Radeleczki
In this paper, we consider tolerances induced by irredundant coverings. Each tolerance on determines a quasiorder by setting if and only if $R…
Monteiro spaces and rough sets determined by quasiorder relations: Models for Nelson algebras
Jouni Järvinen, Sándor Radeleczki
Rough sets induced by quasiorders appear in several constructions using binary relations in computer science. In this paper, a structural characterisation of rough sets induced by…
Efficient Dynamic Polarization of Phosphorus Nuclei in Silicon in Strong Magnetic Fields and Low Temperatures
J. Järvinen, D. Zvezdov, J. Ahokas +11
We demonstrate that the dynamic nuclear polarization (DNP) of phosphorus donors in silicon can be very effective in a magnetic field of 4.6 T and at temperatures below 1 K. The DNP…
Characterizing intermediate tense logics in terms of Galois connections
Wojciech Dzik, Jouni Järvinen, Michiro Kondo
We propose a uniform way of defining for every logic intermediate between intuitionistic and classical logics, the corresponding intermediate minimal tense logic ${\sf LK…
