Boundary-induced geometrical frustration in a square Rydberg-atom lattice
Marco Rigobello, Luka Pavešić, Daniel Jaschke +4
We study geometric defects in square-lattice Rydberg-atom arrays induced by lattice-size parity in the striated density-wave phase. While odd-sized lattices select a single striate…
Scattering and induced false vacuum decay in the two-dimensional quantum Ising model
Luka Pavešić, Marco Di Liberto, Simone Montangero
We study scattering in the quantum Ising model in two dimensions. In the ordered phase, the spectrum contains a ladder of bound states and intertwined scattering resonances, which…
Constrained dynamics and confinement in the two-dimensional quantum Ising model
Luka Pavešić, Daniel Jaschke, Simone Montangero
We investigate the dynamics of the quantum Ising model on two-dimensional square lattices up to spins. In the ordered phase, the model is predicted to exhibit dynami…
Generalized transmon Hamiltonian for Andreev spin qubits
Luka Pavešić, Rok Žitko
We solve the problem of an interacting quantum dot embedded in a Josephson junction between two superconductors with finite charging energy described by the transmon (Cooper pair b…
Exchange interaction between two quantum dots coupled through a superconducting island
Ádám Bácsi, Luka Pavešić, Rok Žitko
We present a theoretical study of a system consisting of a superconducting island and two quantum dots, a possible platform for building qubits and Cooper pair splitters, in the re…
Richardson model with complex level structure and spin-orbit coupling for hybrid superconducting islands: stepwise suppression of pairing and magnetic pinning
Juan Carlos Estrada Saldaña, Luka Pavešič, Alexandros Vekris +3
An epitaxial semiconductor-superconductor nanowire is a superconducting system with a complex level structure originating from hybridization: in addition to a dense set of higher-e…
Excitations in a superconducting Coulombic energy gap
Juan Carlos Estrada Saldaña, Alexandros Vekris, Luka Pavešič +4
Cooper pairing and Coulomb repulsion are antagonists, producing distinct energy gaps in superconductors and Mott insulators. When a superconductor exchanges unpaired electrons with…
Subgap states in superconducting islands
Luka Pavešić, Daniel Bauernfeind, Rok Žitko
We study an interacting quantum dot in contact with a superconducting island described by the Richardson model with a Coulomb repulsion term controlling the number of electrons on…
