Boundary phases and thermodynamics of the Kondo spin- chain: from overscreened Kondo to boundary-bound states
Abay Zhakenov, Pradip Kattel, Andreas Gleis +1
We study a spin- impurity coupled to the boundary of a strongly correlated spin- Takhtajan--Babujian chain, an integrable model whose low-energy physics is described by…
Primordial Dirac Leptogenesis
Aqeel Ahmed, Juan P. Garcés, Manfred Lindner
We present a novel realization of Dirac leptogenesis based on the post-inflationary reheating phase of the early universe. An asymmetry generated within the scalar sector via CP-vi…
The quantum criticality of the Standard Model and the hierarchy problem
Juan P. Garcés, Florian Goertz, Manfred Lindner +1
The naturalness principle has long guided efforts to understand physics beyond the Standard Model, with the hierarchy problem as the central issue. We revisit the role of quantum c…
Radiative Symmetry Breaking with a Scale Invariant Seesaw
Aqeel Ahmed, Juan P. Garcés, Manfred Lindner
We study a scale invariant inverse seesaw model that radiatively generates the electroweak scale, the Standard Model (SM) neutrino masses, and stabilizes the electroweak vacuum. Pr…
