The Factor Width Rank of a Matrix
Nathaniel Johnston, Shirin Moein, Sarah Plosker
A matrix is said to have factor width at most if it can be written as a sum of positive semidefinite matrices that are non-zero only in a single principal submatri…
Absolutely -Incoherent Quantum States and Spectral Inequalities for Factor Width of a Matrix
Nathaniel Johnston, Shirin Moein, Rajesh Pereira +1
We investigate the set of quantum states that can be shown to be -incoherent based only on their eigenvalues (equivalently, we explore which Hermitian matrices can be shown to h…
Majorization and Semi-Doubly Stochastic Operators on
Seyed Mahmoud Manjegani, Shirin Moein
This article is devoted to a study of majorization based on semi-doubly stochastic operators (denoted by ) on when is a -finite measure space. We…
Birkhoff-James Orthogonality in the Trace Norm, with Applications to Quantum Resource Theories
Nathaniel Johnston, Shirin Moein, Rajesh Pereira +1
We develop numerous results that characterize when a complex Hermitian matrix is Birkhoff-James orthogonal, in the trace norm, to a (Hermitian) positive semidefinite matrix or set…
A simplified and unified generalization of some majorization results
Shirin Moein, Rajesh Pereira, Sarah Plosker
We consider positive, integral-preserving linear operators acting on space, known as stochastic operators or Markov operators. We show that, on finite-dimensional spaces, any…
