An upper bound for the purity of absolutely positive partial transpose states
Anh T. Tran
A quantum state is called absolutely separable (resp. absolutely positive partial transpose (APPT)) if it remains separable (resp. positive partial transpose (PPT)) under any globa…

Algebraic properties of twisted Alexander polynomial and Reidemeister torsion of torus knots
Takayuki Morifuji, Anh T. Tran
In this paper we prove that every coefficient of twisted Alexander polynomials of torus knots associated with irreducible -representations is an -val…

Multiplicity of non-acyclic -representations and L-functions of the odd-twisted Whitehead links
Léo Bénard, Ryoto Tange, Anh T. Tran +1
We study the divisor of the Reidemeister torsion on the variety of irreducible -characters of certain knots and links, and provide a geometric interpretation…
