A new rung on the ladder: exploring topological frustration towards two dimensions
Alberto Giuseppe Catalano, Nora Reinić, Gianpaolo Torre +5
Topological frustration arises when boundary conditions impose geometric frustration in a quantum system, creating delocalized defects in the ground states and profoundly altering…
Long-range entanglement and topological excitations
Gianpaolo Torre, Jovan Odavić, Pierre Fromholz +2
Topological order comes in different forms, and its classification and detection is an important field of modern research. In this work, we show that the Disconnected Entanglement…
Effects of defects in the XY chain with frustrated boundary conditions
Gianpaolo Torre, Vanja Marić, Fabio Franchini +1
It has been recently proven that new types of bulk, local order can ensue due to frustrated boundary condition, that is, periodic boundary conditions with an odd number of lattice…
