Radiative Corrections as the Origin of Spontaneous Symmetry Breaking [PDF]

, 1973
We investigate the possibility that radiative corrections may produce spontaneous symmetry breakdown in theories for which the semiclassical (tree) approximation does not indicate such breakdown.

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 rotational symmetry breaking in KTaO3 heterointerface superconductors [PDF]

Nature Communications, 2021
Broken symmetries play a fundamental role in superconductivity and influence many of its properties in a profound way. Understanding these symmetry breaking states is essential to elucidate the various exotic quantum behaviors in non-trivial ...

Carrollian Fluids and Spontaneous Breaking of Boost Symmetry. [PDF]

Physical Review Letters, 2023
In the hydrodynamic regime, field theories typically have their boost symmetry spontaneously broken due to the presence of a thermal rest frame although the associated Goldstone field does not acquire independent dynamics.

Asymmetric balance in symmetry breaking

Physical Review Research, 2020
Spontaneous symmetry breaking is central to our understanding of physics and explains many natural phenomena, from cosmic scales to subatomic particles.

Crystal time-reversal symmetry breaking and spontaneous Hall effect in collinear antiferromagnets [PDF]

Science Advances, 2019
Identification of a previously overlooked spontaneous Hall effect mechanism creates opportunities in low-dissipation spintronics. Electrons, commonly moving along the applied electric field, acquire in certain magnets a dissipationless transverse ...

Mach's Principle and Model for a Broken Symmetric Theory of Gravity [PDF]

, 2002
We investigate spontaneous symmetry breaking in a conformally invariant gravitational model. In particular, we use a conformally invariant scalar tensor theory as the vacuum sector of a gravitational model to examine the idea that gravitational coupling ...

Pseudo-spontaneous U(1) symmetry breaking in hydrodynamics and holography [PDF]

Journal of High Energy Physics, 2021
We investigate the low-energy dynamics of systems with pseudo-spontaneously broken U(1) symmetry and Goldstone phase relaxation. We construct a hydrodynamic framework which is able to capture these, in principle independent, effects.

Strong-to-Weak Spontaneous Symmetry Breaking in Mixed Quantum States [PDF]

PRX Quantum
Symmetry in mixed quantum states can manifest in two distinct forms: , where each individual pure state in the quantum ensemble is symmetric with the same charge, and , which applies only to the entire ensemble.
