Solution-phase fluorination of nanodiamond: near-surface NV activation and spin relaxation
Szabolcs Czene, Olga Krafcsik, Nikoletta Jegenyés +4
Nanodiamonds hosting luminescent point defects, known as fluorescent nanodiamonds (FND), are a leading platform for quantum technology. The nitrogen-vacancy (NV) centre is the most…
Thiolation and PEGylation of silicon carbide nanoparticle
Péter Rózsa, Olga Krafcsik, Zsolt Czigány +3
In this study, we implement thiol termination on the surface of few-nanometer-sized silicon carbide (SiC) nanoparticles (NPs) to enable further applications, such as fluorescent bi…
Materials and Spin Characteristics of Nanodiamonds Partially Covered with Amino Groups and Embedded with Nitrogen-Vacancy Color Centers
Nikoletta Jegenyes, Vladimir Verkhovlyuk, Szabolcs Czene +5
Fluorescent nanodiamonds (FNDs) with optically read qubits hold great potential for detecting electric and magnetic fields, temperature, and other nanoscale physicochemical quantit…
Scalar-Tensor theories from Plebanski gravity
David Beke
We study a modification of the Plebanski action, which generically corresponds to a bi-metric theory of gravity, and identify a subclass which is equivalent to the Bergmann-Wagoner…
Pauli-Fierz mass term in modified Plebanski gravity
David Beke, Giovanni Palmisano, Simone Speziale
We study SO(4) BF theory plus a general quadratic potential, which describes a bi- metric theory of gravity. We identify the profile of the potential leading to a Pauli-Fierz mass…
Scalar-Tensor theory as a singular subsector of Λ(ϕ) Plebanski gravity
D. Beke
It is shown that, in the absence of matter fields, the coupling of a scalar field to the non-chiral Plebanski action can be obtained by relaxing the trace component of the simplici…
Killing spinor space-times and constant-eigenvalue Killing tensors
D. Beke, N. Van den Bergh, L. Wylleman
A class of Petrov type D Killing spinor space-times is presented, having the peculiar property that their conformal representants can only admit Killing tensors with constant eigen…
Expanding perfect fluid generalizations of the C-metric
Lode Wylleman, David Beke
We reexamine Petrov type D gravitational fields generated by a perfect fluid with spatially homogeneous energy density and in which the flow lines form a timelike non-shearing and…
