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…
