Odd thermodynamic limit for the Loschmidt echo
Gianpaolo Torre, Vanja Marić, Domagoj Kuić +2
Is it possible to readily distinguish a system made by an Avogadro's number of identical elements and one with a single additional one? Usually, the answer to this question is nega…
Topological Frustration can modify the nature of a Quantum Phase Transition
Vanja Marić, Gianpaolo Torre, Fabio Franchini +1
Ginzburg-Landau theory of continuous phase transitions implicitly assumes that microscopic changes are negligible in determining the thermodynamic properties of the system. In this…
Quantum Phase Transition induced by Topological Frustration
Vanja Marić, Salvatore Marco Giampaolo, Fabio Franchini
In quantum many-body systems with local interactions, the effects of boundary conditions are considered to be negligible, at least for sufficiently large systems. Here we show an e…
The Frustration of being Odd: How Boundary Conditions can destroy Local Order
Vanja Marić, Salvatore Marco Giampaolo, Domagoj Kuić +1
A central tenant in the classification of phases is that boundary conditions cannot affect the bulk properties of a system. In this work, we show striking, yet puzzling, evidence o…
