Quantum simulation of non-trivial topology
Octavi Boada, Alessio Celi, Maciej Lewenstein +2
We propose several designs to simulate quantum many-body systems in manifolds with a non-trivial topology. The key idea is to create a synthetic lattice combining real-space and in…
From conformal to volume-law for the entanglement entropy in exponentially deformed critical spin 1/2 chains
Giovanni Ramírez, Javier Rodríguez-Laguna, Germán Sierra
An exponential deformation of 1D critical Hamiltonians gives rise to ground states whose entanglement entropy satisfies a volume-law. This effect is exemplified in the XX and Heise…
Which multiphoton states are related via linear optics?
Piotr Migdał, Javier Rodríguez-Laguna, Michał Oszmaniec +1
We investigate which pure states of photons in modes can be transformed into each other via linear optics, without post-selection. In other words, we study the local unitar…
Entanglement in low-energy states of the random-hopping model
Giovanni Ramírez, Javier Rodríguez-Laguna, Germán Sierra
We study the low-energy states of the 1D random-hopping model in the strong disordered regime. The entanglement structure is shown to depend solely on the probability distribution…
