Spontaneous symmetry breaking and chiral symmetry [PDF]
AIP Conference Proceedings, 2000 In this introductory lecture, some basic features of the spontaneous symmetry breaking are discussed. More specifically, $σ$-model, non-linear realization, and some examples of spontaneous symmetry breaking in the non-relativistic system are discussed in details.

Spontaneous Breaking of Rotational Symmetry in Superconductors [PDF]
Physical Review Letters, 2002 We show that homogeneous superconductors with broken spin/isospin symmetry lower their energy via a transition to a novel superconducting state where the Fermi-surfaces are deformed to a quasi-ellipsoidal form at zero total momentum of Cooper pairs. In this state, the gain in the condensation energy of the pairs dominates over the loss in the kinetic ...

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.

Anomaly inflow, accidental symmetry, and spontaneous symmetry breaking
Journal of High Energy Physics, 2020 We consider the 6d (1,0) SCFT on a stack of N M5-branes probing a ℂ2/ℤ2 singularity. In particular, we study its compactifications to four dimensions on a smooth genus-g Riemann surface with non-trivial flavor flux, yielding a family of 4d CFTs.

Spontaneous breaking of the BRST symmetry in the ABJM theory
Physics Letters B, 2014 In this paper, we will analyze the ghost condensation in the ABJM theory. We will perform our analysis in N=1 superspace. We show that in the Delbourgo–Jarvis–Baulieu–Thierry–Mieg gauge the spontaneous breaking of BRST symmetry can occur in the ABJM ...

Spontaneous Symmetry Breaking in 5D Conformally Invariant Gravity
Advances in High Energy Physics, 2016 We explore the possibility of the spontaneous symmetry breaking in 5D conformally invariant gravity, whose action consists of a scalar field nonminimally coupled to the curvature with its potential. Performing dimensional reduction via ADM decomposition,

A holographic perspective on phonons and pseudo-phonons
Journal of High Energy Physics, 2017 We analyze the concomitant spontaneous breaking of translation and conformal symmetries by introducing in a CFT a complex scalar operator that acquires a spatially dependent expectation value.

Fluctuation operators and spontaneous symmetry breaking [PDF]
Journal of Mathematical Physics, 2002 We develop an alternative approach to this field, which was to a large extent developed by Verbeure et al. It is meant to complement their approach, which is largely based on a noncommutative central limit theorem and coordinate space estimates. In contrast to that we deal directly with the limits of l-point truncated correlation functions and show ...
