A bstract We consider the problem of the decomposition of the Rényi entanglement
entropies in theories with a non-abelian symmetry by doing a thorough analysis of Wess …

We propose an explicit formulation of the physical subspace for a (1+ 1)-dimensional SU (2)
lattice gauge theory, where the gauge degrees of freedom are integrated out. Our …

A bstract We argue that corner contributions in gravity action (Hayward term) capture the
essence of gravity edge modes, which lead to gravitational area entropies, such as the black …

In this paper, we argue that holographic complexity should be a basis-dependent quantity.
Computational complexity of a state is defined as a minimum number of gates required to …

In order to understand the puzzle of the free energy of an individual quark in QCD, we
explicitly construct ensembles with quark numbers NV≠ 0 mod 3, corresponding to nonzero …

We consider entanglement across a planar boundary in flat space. Entanglement entropy is
usually thought of as the von Neumann entropy of a reduced density matrix, but it can also …

A bstract A definition for the entanglement entropy in both Abelian and non-Abelian gauge
theories has been given in the literature, based on an extended Hilbert space construction …

We previously proposed that entanglement across a planar surface can be obtained from
the partition function on a Euclidean hourglass geometry. Here we extend the prescription to …

A bstract In this paper, we explore the question of how different gauge choices in a gauge
theory affect the tensor product structure of the Hilbert space in configuration space. In …

As Schroedinger already recognised one century ago, entanglement is at the core of
quantum mechanics. Nowadays it turns out to be the fundamental notion behind many …
