Grüneisen parameter as an entanglement compass and the breakdown of the Hellmann-Feynman theorem
Lucas Squillante, Luciano S. Ricco, Aniekan Magnus Ukpong +3
The Grüneisen ratio , i.e., the singular part of the ratio of thermal expansion to the specific heat, has been broadly employed to explore both finite- and quantum critical p…
Analogue of atomic collapse for adatoms on rhombohedral multilayer graphene
W. C. Silva, J. E. Sanches, A. M. Freitas +3
We propose that a multi-graphene of ABC-type stacking yields virtual bound states lying within the Coulomb insulating gap of an Anderson-like adatom. Wondrously, a virtual state co…
Valence state and lattice incorporation of Ni in Zn/Co-based magnetic oxides
V. Ney, B. Henne, M. de Souza +5
Ni incorporation has been studied in a comprehensive range of Zn/Co-based magnetic oxides to elucidate it valence state and lattice incorporation. The resulting structural and magn…
Topological charge Fano effect in multi-Weyl semimetals
W. C. Silva, W. N. Mizobata, J. E. Sanches +6
We theoretically analyze the Fano interference in a single impurity multi-Weyl semimetal hybrid system and show the emergence of the topological charge Fano effect in the bulk loca…
Unveiling Majorana Quasiparticles by a Quantum Phase Transition: Proposal of a Current Switch
F. A. Dessotti, L. S. Ricco, Y. Marques +6
We propose a theoretical approach based on an interferometer composed by two quantum dots asymmetrically coupled to isolated Majorana quasiparticles (MQPs), lying on the edges of t…
Probing the Antisymmetric Fano Interference Assisted by a Majorana Fermion
F. A. Dessotti, L. S. Ricco, M. de Souza +2
As the Fano effect is an interference phenomenon where tunneling paths compete for the electronic transport, it becomes a probe to catch fingerprints of Majorana fermions lying on…
Effect of Inter-Adatoms Correlations on the Local Density of States of Graphene
A. C. Seridonio, K. Kristinsson, M. de Souza +4
We discuss theoretically the local density of states (LDOS) of a graphene sheet hosting two distant adatoms located at the center of the hexagonal cells. By putting laterally a Sca…
Charge-Ordering Transition in (TMTTF)X Explored via Dilatometry
Mariano de Souza, Jean-Paul Pouget
Charge-ordering phenomena have been highly topical over the last few years. A phase transition towards a charge ordered state has been observed experimentally in several classes of…
