Crosscap states with tunable entanglement as exact eigenstates of local spin chain Hamiltonians
Márton Mestyán, Balázs Pozsgay
It has been observed recently that various spin chain Hamiltonians admit special zero energy "crosscap" eigenstates. These states are made up of maximally entangled Bell pairs prep…

Exact real time dynamics with free fermions in disguise
István Vona, Márton Mestyán, Balázs Pozsgay
We consider quantum spin chains with a hidden free fermionic structure, distinct from the Jordan-Wigner transformation and its generalizations. We express selected local operators…

Multi-directional unitarity and maximal entanglement in spatially symmetric quantum states
Márton Mestyán, Balázs Pozsgay, Ian M. Wanless
We consider dual unitary operators and their multi-leg generalizations that have appeared at various places in the literature. These objects can be related to multi-party quantum s…
