Topological two-band electron-hole superconductors with -wave symmetry: Absence of Dirac quasiparticle annihilation in magic-angle twisted trilayer graphene
Senne Van Loon, Carlos A. R. Sa de Melo
We discuss a two-band model for two-dimensional superconductors with electron and hole bands separated by an energy gap and singlet -wave pairing in each band. This type of mode…
Parity violation in ferromagnet-superconductor heterostructures with strong spin-orbit coupling
P. M. Svetlichnyy, Z. Jiang, C. A. R. Sá de Melo
We study spectroscopic properties of ferromagnetic-superconductor heterostructures with strong spin-orbit coupling of the Rashba type and in the presence of exchange fields. The su…
Enhancing decoherence times in superconducting qubits via circuit design
Kaushik Mitra, C. A. R. Sá de Melo
We study decoherence effects in qubits coupled to environments that exhibit resonant frequencies in their spectral function. We model the coupling of the qubit to its environment v…
Evolution from BCS to BKT superfluidity in one-dimensional optical lattices
M. Iskin, C. A. R. S á de Melo
We analyze the finite temperature phase diagram of fermion mixtures in one-dimensional optical lattices as a function of interaction strength. At low temperatures, the system evolv…
Density Induced Quantum Phase Transitions in Triplet Superconductors
R. W. Cherng, C. A. R. Sá de Melo
We consider the possibility of quantum phase transitions in the ground state of triplet superconductors where particle density is the tunning parameter. For definiteness, we focus…
Magnetoresistive Effects in Ferromagnet-Superconductor Multilayers
E. M. Stoudenmire, C. A. R. Sá de Melo
We consider a nanoscale system consisting of Manganite-ferromagnet and Cuprate-superconductor multilayers in a spin valve configuration. The magnetization of the bottom Manganite-f…
The Lifshitz Transition in d-wave Superconductors
S. S. Botelho, C. A. R. Sá de Melo
The BCS to BEC evolution has been recently the focus of studies in superconductors and cold atomic gases. For a d-wave system, we show that a Lifshitz transition occurs at a critic…
F-wave versus P-wave Superconductivity in Organic Conductors
R. W. Cherng, C. A. R. Sá de Melo
Current experimental results suggest that some organic quasi-one-dimensional superconductors exhibit triplet pairing symmetry. Thus, we discuss several potential triplet order para…
Uniform spin susceptibility tensor and quasiparticle density of states in organic quasi-one-dimensional superconductors
R. D. Duncan, R. W. Cherng, C. A. R. Sa de Melo
We perform calculations relating the order parameter symmetry of organic quasi-one-dimensional superconductors to the bulk quasiparticle density of states and the bulk uniform spin…
Order parameter of quasi-one-dimensional superconductors: symmetry features in quasiparticle density of states and spin susceptibility
R. D. Duncan, C. D. Vaccarella, C. A. R. Sá de Melo
Recent experiments indicate that the Bechgaard salts (TMTSF) ClO and (TMTSF) PF may be unconventional triplet superconductors. The quasiparticle density of states a…
Phase Fluctuations and Vortex Lattice Melting in Triplet Quasi-One-Dimensional Superconductors at High Magnetic Fields
C. D. Vaccarella, C. A. R. Sa de Melo
Assuming that the order parameter corresponds to an equal spin triplet pairing symmetry state, we calculate the effect of phase fluctuations in quasi-one-dimensional superconductor…
From BCS to BEC Superconductivity: Spectroscopic Consequences
L. S. Borkowski, C. A. R. Sa de Melo
The evolution from BCS to BEC superconductivity in the s-wave and d-wave channels is analyzed at zero temperature for a two-dimensional superconductor. Spectroscopic quantities for…
