Breaking symmetry, breaking ground [PDF]
Journal of Physics A: Mathematical and Theoretical, 2016 I give a short commentary on a seminal article by T W B Kibble in 1976, "Topology of cosmic domains and strings".

pH‐mediated activation of the lysosomal arginine sensor SLC38A9
FEBS Letters, EarlyView.Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

Spontaneous symmetry breaking of coupled Fabry–Pérot nanocavities
Communications PhysicsRing 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.

Dynamical Manifestation of the Goldstone Phenomenon at 1-loop [PDF]
, 1999 We have calculated the damping rate $\Gamma (|{\bf k}|)$ for classical on-shell Goldstone modes of the O(2) symmetric scalar fields propagating in a thermal medium of the broken symmetry phase taking into account the effect of the explicit symmetry ...

FEBS Letters, EarlyView.Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Spontaneous symmetry breaking in a spin-orbit coupled $f=2$ spinor condensate
, 2015 We study the ground-state density profile of a spin-orbit coupled $f=2$ spinor condensate in a quasi-one-dimensional trap. The Hamiltonian of the system is invariant under time reversal but not under parity.

FEBS Open Bio, EarlyView.Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

Breaking strong symmetries in dissipative quantum systems: Bosonic atoms coupled to a cavity
Physical Review Research, 2022 In dissipative quantum systems, strong symmetries can lead to the existence of conservation laws and multiple steady states. In this Letter we investigate a strong symmetry for bosonic atoms coupled to an optical cavity, an experimentally relevant system,

Dilatons for Dense Hadronic Matter
, 2009 The idea that the explicit breaking of scale invariance by the trace anomaly of QCD can be rephrased as a spontaneous breaking has been recently exploited to capture the low-energy strong interaction dynamics of dense (and also hot) matter in terms of ...

Chiral symmetry breaking by a non-Abelian external field in (2+1)-dimensions [PDF]
, 1997 We investigate the effect of a constant external non-Abelian field on chiral symmetry breaking in a (2+1)-dimensional Nambu-Jona-Lasinio model and in 3D QCD by solving the gap equation and the Bethe-Salpeter equation, and also by RG analysis. In the (2+1)
