Domain Wall Control of Topological Qubits in the Kitaev SSH Chain
Griffith Rufo, Sabrina Rufo, Heron Caldas +1
Zero energy states in one dimensional SSH Kitaev hybrid systems have emerged as promising candidates for topological qubits. In our work, we show that introducing a domain wall int…

Quantum and Semi-Classical Signatures of Dissipative Chaos in the Steady State
Griffith Rufo, Sabrina Rufo, Pedro Ribeiro +1
We investigate the quantum-classical correspondence in open quantum many-body systems using the SU(3) Bose-Hubbard trimer as a minimal model. Combining exact diagonalization with s…
