Band twisting and resilience to disorder in long-range topological superconductors
T. O. Puel, O. Viyuela
Planar topological superconductors with power-law-decaying pairing display different kinds of topological phase transitions where quasiparticles dubbed nonlocal-massive Dirac fermi…
Scalable Fermionic Error Correction in Majorana Surface Codes
Oscar Viyuela, Sagar Vijay, Liang Fu
We study the error correcting properties of Majorana Surface Codes (MSC), topological quantum codes constructed out of interacting Majorana fermions, which can be used to store qua…
Phase diagram of the dissipative quantum Ising model on a square lattice
Jiasen Jin, Alberto Biella, Oscar Viyuela +3
The competition between interactions and dissipative processes in a quantum many-body system can drive phase transitions of different order. Exploiting a combination of cluster met…
Topological Phases in Nodeless Tetragonal Superconductors
Santiago Varona, Laura Ortiz, Oscar Viyuela +1
We compute the topological phase diagram of 2D tetragonal superconductors for the only possible nodeless pairing channels compatible with that crystal symmetry. Subject to a Zeeman…
Linked cluster expansions for open quantum systems on a lattice
Alberto Biella, Jiasen Jin, Oscar Viyuela +3
We propose a generalization of the linked-cluster expansions to study driven-dissipative quantum lattice models, directly accessing the thermodynamic limit of the system. Our metho…
Chiral Topological Superconductors Enhanced by Long-Range Interactions
Oscar Viyuela, Liang Fu, Miguel Angel Martin-Delgado
We study the phase diagram and edge states of a two-dimensional p-wave superconductor with long-range hopping and pairing amplitudes. New topological phases and quasiparticles diff…
