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…

Saturation Field as a Direct Probe of Exchange and Single-Ion Anisotropies in Spin-1 Magnets
M. A. R. Griffith, S. Rufo, H. Caldas +3
High magnetic fields provide a direct route to probe the anisotropies that govern spin dynamics in layered magnets. Using the SU(3) bond operator framework for spin 1 systems, we d…

Tricritical behavior of a relativistic field theory in one dimension
Heron Caldas, A. L. Mota
The tricritical behavior in a class of one-dimensional (1D) field theories that exhibit spontaneous symmetry breaking at zero temperature and chemical potential is analyzed. In the…
