Anomalous Spontaneous Symmetry Breaking in non-Hermitian Systems with Biorthogonal Z2-symmetry [PDF]
arXiv, 2020 Landau's spontaneous symmetry breaking theory is a fundamental theory that describes the collective behaviors in many-body systems. It was well known that for usual spontaneous symmetry breaking in Hermitian systems, the order-disorder phase transition with gap closing and spontaneous symmetry breaking occur at the same critical point.

Symmetry-breaking in Chiral Polymerisation [PDF]
Origins of Life and Evolution of Biospheres, 2005 We propose a model for chiral polymerisation and investigate its symmetric and asymmetric solutions. The model has a source species which decays into left- and right-handed types of monomer, each of which can polymerise to form homochiral chains; these chains are susceptible to `poisoning' by the opposite handed monomer. Homochiral polymers are assumed

Medium‐Entropy Engineering of Magnetism in Layered Antiferromagnet CuxNi2(1‐x)CrxP2S6
Advanced Functional Materials, EarlyView.This study explores the aliovalent substitution strategy with Cu and Cr replacing Ni in Ni₂P₂S₆ compounds to engineer magnetism. By creating CuxNi2(1‐x)CrxP2S6 medium‐entropy alloys, the research reveals the evolution of distinct magnetic phases, including the creation of weak ferromagnetism in intermediate compositions.

Journal of High Energy Physics, 2019 Perturbative calculations of the effective potential evaluated at a broken minimum, V min, are plagued by difficulties. It is hard to get a finite and gauge invariant result for V min.

Holographic Symmetry-Breaking Phases in AdS$_3$/CFT$_2$
, 2011 In this note we study the symmetry-breaking phases of 3D gravity coupled to matter. In particular, we consider black holes with scalar hair as a model of symmetry-breaking phases of a strongly coupled 1+1 dimensional CFT.

Diversity of left-right symmetry breaking strategy in animals [version 1; peer review: 2 approved]
F1000Research, 2020 Left-right (L-R) asymmetry of visceral organs in animals is established during embryonic development via a stepwise process. While some steps are conserved, different strategies are employed among animals for initiating the breaking of body symmetry.

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.

Advanced Functional Materials, EarlyView.By employing a partial oxidation strategy, nanosized pores are introduced into MXene nanosheets. The resulting holey MXene exhibits faster ionic transport, achieving an aerial capacitance 2.5 times that of unmodified MXene electrodes, and demonstrates excellent cycling stability, retaining 91.7% of its capacitance after 10 000 cycles.
