Spontaneously broken subsystem symmetries
Journal of High Energy Physics, 2022 We investigate the spontaneous breaking of subsystem symmetries directly in the context of continuum field theories by calculating the correlation function of charged operators. Our methods confirm the lack of spontaneous symmetry breaking in some of the

Tunneling potentials for the tunneling action: gauge invariance
Journal of High Energy Physics, 2022 We formulate a procedure to obtain a gauge-invariant tunneling rate at zero temperature using the recently developed tunneling potential approach. This procedure relies on a consistent power counting in gauge coupling and a derivative expansion.

Dilaton in scalar QFT: a no-go theorem in 4-epsilon and 3-epsilon dimensions
SciPost Physics, 2022 Spontaneous scale invariance breaking and the associated Goldstone boson, the dilaton, is investigated in renormalizable, unitary, interacting non-supersymmetric scalar field theories in $4-\varepsilon$ dimensions.

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 ...

Spontaneous symmetry breaking of arbitrage [PDF]
Physica A: Statistical Mechanics and its Applications, 2012 We introduce the concept of spontaneous symmetry breaking to arbitrage modeling. In the model, the arbitrage strategy is considered as being in the symmetry breaking phase and the phase transition between arbitrage mode and no-arbitrage mode is triggered by a control parameter.

ON THE SYMMETRY OF THE VACUUM IN THEORIES WITH "SPONTANEOUS SYMMETRY BREAKING" [PDF]
International Journal of Modern Physics A, 2011 We review the usual account of the phenomena of spontaneous symmetry breaking, pointing out the common misunderstandings surrounding the issue, in particular within the context of quantum field theory. In fact, the common explanations one finds in this context, indicate that under certain conditions corresponding to the situation called spontaneous ...

Spontaneous breaking of multipole symmetries
Physical Review B, 2022 Multipole symmetries are of interest both as a window on fracton physics and as a crucial ingredient in realizing new universality classes for quantum dynamics. Here we address the question of whether and when multipole symmetries can be spontaneously broken, both in thermal equilibrium and at zero temperature.

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.
