The phase‐space formulation of quantum mechanics has recently seen increased use in
testing quantum technologies, including methods of tomography for state verification and …

We present a complete study of ΔS= 2 and ΔB= 2 processes in a warped extra dimensional
model with a custodial protection of Zb L bar b L, including ε K, ΔM K, ΔM s, ΔM d, A SL q, ΔΓ …

In a previous paper [1] an Euler angle parametrization for SU (4) was given. Here we
present the derivation of a generalized Euler angle parametrization for SU (N). The formula …

A bstract We introduce coherent states averaged over a gauge group action to study
correlators of half BPS states in\(\mathcal {N}\)= 4 SYM theory. The overlaps of these …

In this paper we give an explicit parametrization for all two-qubit density matrices. This is
important for calculations involving entanglement and many other types of quantum …

A bstract We study generating functions of\(\frac {1}{4}\)-BPS states in\(\mathcal {N}\)= 4
super Yang-Mills at finite N by attempting to generalize the Harish-Chandra-Itzykson-Zuber …

We present a digitization scheme for the lattice SU (2) gauge theory Hamiltonian in the
magnetic basis, where the gauge links are unitary and diagonal. The digitization is obtained …

In a previous paper [J. Phys. A: Math. Gen. 35 (2002) 10467] an Euler angle
parameterization for SU (N) was given. Here we present a generalized Euler angle …

The entanglement asymmetry measures the extent to which a symmetry is broken within a
subsystem of an extended quantum system. Here, we analyse this quantity in Haar random …

We present a set of N-dimensional functions, based on generalized SU (N)-symmetric
coherent states, that represent finite-dimensional Wigner, Q-and P-functions. We then show …
