The pygmy dipole strength, the neutron radius of Pb and the symmetry energy
X. Roca-Maza, M. Brenna, M. Centelles +5
The accurate characterization of the nuclear symmetry energy and its density dependence is one of the outstanding open problems in nuclear physics. A promising nuclear observable i…
Low-lying dipole response: isospin character and collectivity in Ni, Sn and Pb
X. Roca-Maza, G. Pozzi, M. Brenna +2
The isospin character, the collective or single-particle nature, and the sensitivity to the slope of the nuclear symmetry energy of the low-energy isovector dipole response (known…
Symmetry and planar chirality of a protein measured on an angular basis in a transmission electron microscope
A. H. Tavabi, P. Rosi, R. B. G. Ravelli +16
In quantum mechanics, each conserved quantity (e.g., energy, position, linear momentum and angular momentum) is associated with a Hermitian operator. Its expected value can then be…
The Föppl-von Kármán equations of elastic plates with initial stress
P. Ciarletta, G. Pozzi, D. Riccobelli
Initially stressed plates are widely used in modern fabrication techniques, such as additive manufacturing and UV lithography, for their tunable morphology by application of extern…
Generation of electron vortex beams with over 1000 orbital angular momentum quanta using a tuneable electrostatic spiral phase plate
A. H. Tavabi, P. Rosi, A. Roncaglia +9
We report the use of an electrostatic MEMS-based device to produce high quality electron vortex beams with more than 1000 quanta of orbital angular momentum (OAM). Diffraction and…
