Linear stability analysis of chemical mechanism, Listanalchem: A tool for the search of spontaneous mirror symmetry breaking

MethodsX, 2023
Homochirality, the phenomenon by which one of two virtually identical (non-superimposable mirror images) compounds is favored over the other in the chemistry of life, has been regarded as a requisite for the emergence of all living things on earth ...

Spontaneous Twin Symmetry Breaking [PDF]

, 2019
We consider a twin Higgs scenario where the $Z_2$ twin symmetry is broken spontaneously, not explicitly. This scenario provides an interesting interpretation of the Higgs metastability in the standard model; the $SU(4)$ breaking scale $f$ is determined ...

Non-Hermitian non-Abelian topological insulators with PT symmetry

Physical Review Research, 2021
We study a non-Hermitian non-Abelian topological insulator preserving PT symmetry, where the non-Hermitian term represents nonreciprocal hoppings. As it increases, a spontaneous PT symmetry breaking transition occurs in the perfect-flat band model from a

Supersymmetry Breaking, R-Symmetry Breaking and Metastable Vacua

, 2007
Models of spontaneous supersymmetry breaking generically have an R-symmetry, which is problematic for obtaining gaugino masses and avoiding light R-axions.

Spontaneous breaking of non-relativistic scale symmetry

Journal of High Energy Physics, 2017
We analyze the mechanism of spontaneous symmetry breaking of scale invariance in Galilean invariant field theories. We show that the existence of a dynamic gapless dilaton mode depends on whether the U(1) particle number or the Galilean boost symmetry ...

Entanglement and Spontaneous Symmetry Breaking in Quantum Spin Models

, 2003
It is shown that spontaneous symmetry breaking does not modify the ground-state entanglement of two spins, as defined by the concurrence, in the XXZ- and the transverse field Ising-chain.

Spontaneous symmetry breaking and Nambu–Goldstone modes in open classical and quantum systems [PDF]

Progress of Theoretical and Experimental Physics, 2019
We discuss spontaneous symmetry breaking of open classical and quantum systems. When a continuous symmetry is spontaneously broken in an open system, a gapless excitation mode appears corresponding to the Nambu–Goldstone mode.

Spontaneous symmetry breaking and response functions [PDF]

, 2004
We study the quantum phase transition occurring in an infinite homogeneous system of spin 1/2 fermions in a non-relativistic context. As an example we consider neutrons interacting through a simple spin-spin Heisenberg force.

Spontaneous symmetry breaking of coupled Fabry–Pérot nanocavities

Communications Physics
Ring cavities are quickly emerging as preferential platforms to investigate spontaneous symmetry breaking. However, research on handedness polarisation splitting within Kerr-coupled cavities is yet at a preliminary stage.

Spontaneous symmetry breaking and trapping of temporal Kerr cavity solitons by pulsed or amplitude-modulated driving fields [PDF]

, 2018
We report on a systematic study of temporal Kerr cavity soliton dynamics in the presence of pulsed or amplitude-modulated driving fields. In stark contrast to the more extensively studied case of phase modulations, we find that Kerr cavity solitons are ...
