Fractionalization of Majorana-Ising-type quasiparticles
J. E. Sanches, L. T. Lustosa, L. S. Ricco +4
We theoretically investigate the spectral properties of a quantum impurity (QI) hosting the here proposed {Majorana-Ising-type quasiparticle (MIQ) excitation}. It arises from the c…
Topological isoconductance signatures in Majorana nanowires
L. S. Ricco, J. E. Sanches, Y. Marques +4
We consider transport properties of a hybrid device composed by a quantum dot placed between normal and superconducting reservoirs, and coupled to a Majorana nanowire: a topologica…
Giant caloric effects close to critical end point
Lucas Squillante, Isys F. Mello, A. C. Seridonio +1
The electrocaloric effect (ECE), i.e., the reversible temperature change due to the adiabatic variation of the electric field, is of great interest due to its potential technologic…
Epidemics, the Ising-model and percolation theory: a comprehensive review focussed on Covid-19
Isys F. Mello, Lucas Squillante, Gabriel O. Gomes +2
We revisit well-established concepts of epidemiology, the Ising-model, and percolation theory. Also, we employ a spin = 1/2 Ising-like model and a (logistic) Fermi-Dirac-like f…
Low-temperature lattice effects in the spin-liquid candidate -(BEDT-TTF)Cu(CN)
Rudra Sekhar Manna, Steffi Hartmann, Elena Gati +3
The quasi-two-dimensional organic charge-transfer salt -(BEDT-TTF)Cu(CN) is one of the prime candidates for a quantum spin-liquid due the strong spin frustration of…
Antibonding Ground state of Adatom Molecules in Bulk Dirac Semimetals
Y. Marques, A. E. Obispo, L. S. Ricco +3
The ground state of the diatomic molecules in nature is inevitably bonding, and its first excited state is antibonding. We demonstrate theoretically that, for a pair of distant ada…
Encrypting Majorana Fermions-qubits as Bound States in the Continuum
L. H. Guessi, F. A. Dessotti, Y. Marques +5
We theoretically investigate a topological Kitaev chain connected to a double quantum-dot (QD) setup hybridized with metallic leads. In this system we observe the emergence of two…
Realization of anomalous multiferroicity in free-standing graphene with magnetic adatoms
Y. Marques, L. S. Ricco, F. A. Dessotti +4
It is generally believed that free-standing graphene does not demonstrate any ferroic properties. In the present work we revise this statement and show that single graphene sheet w…
The Einstein specific heat model for finite systems
E. Boscheto, M. de Souza, A. López-Castillo
The theoretical model proposed by Einstein to describe the phononic specific heat of solids as a function of temperature consists the very first application of the concept of energ…
Grüneisen Parameter for Gases
Mariano de Souza, Paulo Menegasso, Ricardo Paupitz +2
The Grüneisen ratio (), i.e.\,the ratio of the linear thermal expansivity to the specific heat at constant pressure, quantifies the degree of anharmonicity of the potential gove…
Effect of Interdots Electronic Repulsion in the Majorana Signature for a Double Dot Interferometer
L. S. Ricco, Y. Marques, F. A. Dessotti +2
We investigate theoretically the features of the Majorana hallmark in the presence of Coulomb repulsion between two quantum dots describing a spinless Aharonov-Bohm-like interferom…
Decay of bound states in the continuum of Majorana fermions induced by vacuum fluctuations: Proposal of qubit technology
L. S. Ricco, Y. Marques, F. A. Dessotti +3
We report on a theoretical investigation of the interplay between vacuum fluctuations, Majorana quasiparticles (MQPs) and bound states in the continuum (BICs) by proposing a new ve…
Quantum phase transition triggering magnetic BICs in graphene
L. H. Guessi, Y. Marques, R. S. Machado +6
Graphene hosting a pair of collinear adatoms in the phantom atom configuration has pseudogap with cubic scaling on energy, which leads to the appearance…
Specific Heat Anomalies in Solids Described by a Multilevel Model
Mariano de Souza, Ricardo Paupitz, Antonio Seridonio +1
Specific heat measurements constitute one of the most powerful experimental methods to probe fundamental excitations in solids. After the proposition of Einstein's model, more than…
Fano fingerprints of Majoranas in Kitaev dimers of superconducting adatoms
F. A. Dessotti, L. S. Ricco, Y. Marques +5
We investigate theoretically a Fano interferometer composed by STM and AFM tips close to a Kitaev dimer of superconducting adatoms, in which the adatom placed under the AFM tip, en…
