Nielsen complexity with multiple cost factors

Marcos Rios Ribeiro, Diego Trancanelli

We investigate Nielsen's geometric approach to quantum complexity in the presence of multiple cost factors, extending the standard framework where a single penalty distinguishes ea…

Strong coupling dynamics of defect RG flows in ABJM

Marco S. Bianchi, Luigi Castiglioni, Silvia Penati +2

Wilson loop operators in ABJM theory provide a rich arena for studying defect conformal field theories (dCFTs) and the renormalization group (RG) flows connecting them. While these…

Framed defects in ABJ(M)

Marco S. Bianchi, Luigi Castiglioni, Silvia Penati +2

We investigate the role of framing in a family of 1/24 BPS Wilson loops in ABJ(M) theory, which define flows between 1/6 BPS and the 1/2 BPS superconformal fixed points. We analyze…

Conformal defects and RG flows in ABJM

Luigi Castiglioni, Silvia Penati, Marcia Tenser +1

Defects play a central role in many contexts, from condensed matter to quantum gravity. The situations in which the bulk theory is conformal and the defect inherits part of this sy…

Framing fermionic Wilson loops in ABJ(M)

Marco S. Bianchi, Luigi Castiglioni, Silvia Penati +2

Framing plays a central role in the evaluation of Wilson loops in theories with Chern-Simons actions. In pure Chern-Simons theory, it guarantees topological invariance, while in th…

Interpolating Bremsstrahlung function in ABJM

Luigi Castiglioni, Silvia Penati, Marcia Tenser +1

In ABJM theory, enriched RG flows between circular 1/6 BPS bosonic and 1/2 BPS fermionic Wilson loops have been introduced in arXiv:2211.16501. These flows are triggered by deforma…
