μ − τ reflection symmetry and its explicit breaking for leptogenesis in a minimal seesaw model [PDF]
Modern Physics Letters A, 2019 The minimal seesaw framework, embroiling the Dirac neutrino mass matrix [Formula: see text] and the Majorana neutrino mass matrix [Formula: see text], is quite successful to explain the current global-fit results of neutrino oscillation data.

Pseudo-Goldstone excitations in chiral Yukawa-theories with quadratic explicit symmetry breaking [PDF]
, 2017 The symmetry breakdown pattern is studied in models containing one fermion flavor multiplet and a multicomponent scalar field, supplemented with a chiral Yukawa-interaction, and in presence of an explicit symmetry breaking source quadratic in the scalar ...

Persistence of stationary motion under explicit symmetry breaking perturbation [PDF]
Nonlinearity, 2019 Explicit symmetry breaking occurs when a dynamical system having a certain symmetry group is perturbed to a system which has strictly less symmetry. We give a geometric approach to study this phenomenon in the setting of Hamiltonian systems. We provide a

Bound of diffusion constants from pole-skipping points: spontaneous symmetry breaking and magnetic field [PDF]
Journal of High Energy Physics, 2021 We investigate the properties of pole-skipping of the sound channel in which the translational symmetry is broken explicitly or spontaneously. For this purpose, we analyze, in detail, not only the holographic axion model, but also the magnetically ...

Symmetry Breaking Soliton, Breather, and Lump Solutions of a Nonlocal Kadomtsev–Petviashvili System
Complexity, 2020 The Kadomtsev–Petviashvili equation is one of the well-studied models of nonlinear waves in dispersive media and in multicomponent plasmas. In this paper, the coupled Alice-Bob system of the Kadomtsev–Petviashvili equation is first constructed via the ...

Strange quark matter in the presence of explicit symmetry breaking interactions [PDF]
, 2015 It is shown that a first order transition associated with a jump in the strange quark mass appears in a generalized 3 flavour Nambu--Jona-Lasinio (NJL) treatment of quark matter.

Diagnosing strong-to-weak symmetry breaking via Wightman correlators
Communications PhysicsSymmetry plays a fundamental role in quantum many-body physics, and a central concept is spontaneous symmetry breaking. Recent developments highlight new symmetry-breaking patterns known as strong-to-weak spontaneous symmetry breaking, characterized by ...

Explicit flavor symmetry breaking and holographic compact stars [PDF]
, 2015 We study the effects of flavor symmetry breaking on holographic dense matter and compact stars in the D4/D6 model. To this end, two light flavors and one intermediate mass flavor are considered. For two light quarks, we investigate how the strong isospin

Formation of Topological Defects with Explicit Symmetry Breaking [PDF]
Physical Review Letters, 1996 We demonstrate a novel mechanism for the formation of topological defects in a first order phase transition for theories in the presence of small explicit symmetry breaking terms.
