Spontaneous Symmetry Breaking and Nambu–Goldstone Bosons in Quantum Many-Body Systems
Published 2010-04-01“…Spontaneous symmetry breaking is a general principle that constitutes the underlying concept of a vast number of physical phenomena ranging from ferromagnetism and superconductivity in condensed matter physics to the Higgs mechanism in the standard model of elementary particles. …”

(Pseudo)goldstinos, SUSY fluids, Dirac gravitino and gauginos
Published 2014-04-01“…First, we consider a super-Higgs mechanism when supersymmetry breaking is induced by neither an F-term nor a D-term but related to a more general stress energy-momentum tensor. …”

Constrained instanton approximation of Skyrmions with massive pions
Published 2022-12-01“…The fact that the gauge field acquires a nonzero mass due to the Higgs mechanism implies that a constrained instanton decays exponentially far from its center, and so does the Skyrmion configuration that it generates via the Atiyah-Manton construction. …”

The Hasse diagram of the moduli space of instantons
Published 2022“…In this note we explore the Hasse diagram of this moduli space from several perspectives — using the partial Higgs mechanism, using brane systems and using quiver subtraction — having to refine previously developed techniques. …”

Vortex-mediated relaxation of magnon BEC into light Higgs quasiparticles
Published 2021-07-01“…We study the vortex-Higgs mechanism: The vortices relax the requirement for momentum conservation, allowing the optical magnons of the BEC to transform into light Higgs quasiparticles. …”

Quantum gauge freedom in very special relativity
Published 2017-02-01“…It is observed that the gaugeon field together with gauge field naturally acquire mass, which is different from the conventional Higgs mechanism. The quantum gauge transformation implements a shift in gauge parameter. …”

The universe from a single particle. Part II
Published 2021-10-01“…Abstract We continue to explore, in the context of a toy model, the hypothesis that the interacting universe we see around us could result from single particle (undergraduate) quantum mechanics via a novel spontaneous symmetry breaking (SSB) acting at the level of probability distributions on Hamiltonians (rather than on states as is familiar from both Ginzburg-Landau superconductivity and the Higgs mechanism). In an earlier paper [1] we saw qubit structure emerge spontaneously on ℂ4 and ℂ8, and in this work we see ℂ6 spontaneously decomposing as ℂ2 ⊗ ℂ3 and very curiously ℂ5 (and ℂ7) splitting off one (one or three) directions and then factoring. …”

Many-Body Localization with Long-Range Interactions

Hagedorn-like transition at high supersymmetry breaking scale
Published 2019-08-01“…Abstract We consider phase transitions occurring in four-dimensional heterotic orbifold models, when the scale of spontaneous breaking of N $$ \mathcal{N} $$ = 1 supersymmetry is of the order of the string scale. The super-Higgs mechanism is implemented by imposing distinct boundary conditions for bosons and fermions along an internal circle of radius R. …”

Spontaneous symmetry breaking from an on-shell perspective
Published 2024-02-01“…By demanding that on-shell IR amplitudes match onto on-shell UV amplitudes in the high energy limit, we reproduce the Higgs mechanism and generate masses for spins-1/2 and 1, find that there is a subgroup H ⊆ G in the IR, and other interesting relations. …”
