Anomalous current fluctuations in the stochastic XNOR hopping model
Balázs Pozsgay
We consider fluctuations of the spin current in the stochastic XNOR process, a kinetically constrained hopping model in one spatial dimension. We formulate three conjectures with e…
On the two-copy distillability of Werner states and a new partial trace inequality
Thomas C. Fraser, Felix Huber, Balázs Pozsgay +1
Problem 5 in {\it Five Open Problems in Quantum Information Theory} [PRX Quantum 3, 010101 (2022)], asks whether the two-ququart Werner state is two-copy dis…
A free fermions in disguise model with claws
Kohei Fukai, István Vona, Balázs Pozsgay
Recently, several spin chain models have been discovered that admit solutions in terms of "free fermions in disguise." A graph-theoretical treatment of such models was also establi…
Free fermions in disguise without exponential degeneracies
Balázs Pozsgay
Recently, a number of spin chain models have been discovered that are solvable via hidden free-fermionic structures, going beyond the Jordan-Wigner paradigm. However, all examples…
Solving models with generalized free fermions II: Path-product expansion and conserved charges
Kohei Fukai, Balázs Pozsgay, István Vona
Free-fermion solvability in quantum spin systems is increasingly understood to be governed by a graph Clifford algebra defined from the frustration graph of the Hamiltonian. When t…
Graph restricted tensors: building blocks for holographic networks
Rafaĺ BistroÅ, Márton Mestyán, Balázs Pozsgay +1
We analyze few-body quantum states with particular correlation properties imposed by the requirement of maximal bipartite entanglement for selected partitions of the system into tw…
