Simulation of vortex-antivortex pair production in a phase transition with explicit symmetry breaking [PDF]
, 1998 We carry out numerical simulation of the formation of U(1) global vortices in a first order phase transition in 2+1 dimensions in the presence of small explicit symmetry breaking.

Axion dark matter with explicit Peccei-Quinn symmetry breaking in the axiverse [PDF]
Journal of Cosmology and Astroparticle Physics, 2023 It was shown that the required high quality of the Peccei-Quinn (PQ) symmetry can be a natural outcome of the multiple QCD axions model. In the axiverse, a hypothetical mass mixing between the QCD axions and axion-like particles (ALPs) can occur, which ...

Diagnosis of explicit symmetry breaking in the tight-binding constructions for symmetry-protected topological systems [PDF]
, 2020 It has been well established that for symmetry protected topological systems, the non-trivial topology prevents a real space representation using exponentially localized Wannier wavefunctions (WFs) in all directions, unless the protecting symmetry is ...

Holographic Non-Abelian Flavour Symmetry Breaking [PDF]
Universe, 2023 We investigate a holographic model for both spontaneous and explicit symmetry breaking of non-abelian flavour symmetries. This consists of a bottom-up model inspired by the top-down D3/probe D7-brane model.

Cosmological effects of Peccei-Quinn symmetry breaking on QCD axion dark matter [PDF]
Journal of Cosmology and Astroparticle Physics, 2022 We study cosmological effects of explicit Peccei-Quinn breaking on the QCD axion dark matter. We find that the axion abundance decreases or increases significantly depending on the initial position, even for a tiny Peccei-Quinn breaking that satisfies ...

Inhomogeneous phases in the quark-meson model with explicit chiral-symmetry breaking [PDF]
The European Physical Journal Special Topics, 2020 We investigate the existence of inhomogeneous chiral phases in the quark-meson model with explicit chiral-symmetry breaking. We find that the inhomogeneous region shrinks with increasing pion masses but survives for the physical value of mπ.

Quantum noise as a symmetry-breaking field [PDF]
Physical review B, 2022 We investigate the effect of quantum noise on the measurement-induced quantum phase transition in monitored random quantum circuits. Using the efficient simulability of random Clifford circuits, we find that the transition is broadened into a crossover ...

Proper-time method for unequal masses
Physics Letters B, 2021 The result of removing of heavy non-equal mass particles from the theory can be described, at low energy, by the effective action, which is a series in inverse-square powers of the mass.

Breaking rotations without violating the KSS viscosity bound
Journal of High Energy Physics, 2023 We revisit the computation of the shear viscosity to entropy ratio in a holographic p-wave superfluid model, focusing on the role of rotational symmetry breaking.

Replica Symmetry Breaking in Random Non-Hermitian Systems [PDF]
, 2022 Recent studies have revealed intriguing similarities between the contribution of wormholes to the gravitational path integral and the phenomenon of replica symmetry breaking observed in spin glasses and other disordered systems.
