Gravitational Coleman-Weinberg mechanism
Journal of High Energy Physics, 2023 The Coleman-Weinberg mechanism provides a procedure by which a scalar field, which initially has no mass parameters, acquires a mass due to the anomalous nature of scale symmetry.

Torsional deformation of nonrelativistic string theory
Journal of High Energy Physics, 2021 Nonrelativistic string theory is a self-contained corner of string theory, with its string spectrum enjoying a Galilean-invariant dispersion relation. This theory is unitary and ultraviolet complete, and can be studied from first principles.

Spontaneous symmetry breaking in light cone quantum field theory
Physics Letters B, 1991 Abstract We reexamine light cone quantisation of scalar field theories with a spontaneously broken internal symmetry. To this end we use the Dirac-Bergmann algorithm for quantisation of constrained systems. Carefully taking into account the zero modes with light cone momentum k + = 0, we obtain secondary constraints which determine the (tree level)

Spontaneous symmetry breaking in tensor theories
Journal of High Energy Physics, 2019 In this work we study spontaneous symmetry breaking patterns in tensor models. We focus on the patterns which lead to effective matrix theories transforming in the adjoint of U(N).

Symmetric Gapped Interfaces of SPT and SET States: Systematic Constructions
Physical Review X, 2018 Symmetry-protected topological (SPT) states have boundary ’t Hooft anomalies that obstruct the effective boundary theory realized in its own dimension with UV completion and with an on-site G-symmetry.

Modification entropy of Kerr–Sen-like black hole in Lorentz-breaking bumblebee gravity
Frontiers in PhysicsThe Lorentz symmetry breaking theory not only affects the space–time background but also the dynamic behavior of bosons and fermions in curved space–time.

Journal of High Energy Physics, 2020 Recently, infinite families of massive Feynman integrals were found to feature an unexpected Yangian symmetry. In the massless case, similar integrability properties are understood via the interpretation of individual Feynman integrals as correlators in ...

Entropy, 2016 The Kibble–Zurek scaling describes the driven critical dynamics starting with an equilibrium state far away from the critical point. Recently, it has been shown that scaling behaviors also exist when the fluctuation term changes starting near the ...

Advanced Functional Materials, EarlyView.From a database of 170 pentagonal 2D materials, 4 candidates exhibiting altermagnetic ordering are screened. Furthermore, the spin‐splitting and unconventional boundary states in the pentagonal 2D altermagnetic monolayer MnS2 are investigated. A MnS2‐based altermagnetic tunneling junction is designed and, through ab initio quantum transport simulations,
