DOI: 10.1088/1367-2630/acd8e8
Abstract: An outstanding challenge involves understanding the many-particle entanglement of liquid states of quantum matter that arise in systems of interacting electrons. The Fermi liquid (FL) shows a violation of the area-law in real-space entanglement entropy… read more here.

DOI: 10.1088/1674-1056/ab9288
Abstract: Entanglement is the key resource in quantum information processing, and an entanglement witness (EW) is designed to detect whether a quantum system has any entanglement. However, prior knowledge of the target states should be known… read more here.

DOI: 10.1103/physrevlett.130.131601
Abstract: We calculate the amount of entanglement shared by two intervals in the ground state of a (1+1)-dimensional conformal field theory (CFT), quantified by an entanglement measure E based on the computable cross norm (CCNR) criterion.… read more here.
