The geometry of gauged (super)conformal mechanics
Journal of High Energy Physics, 2022 Motivated by recently explored examples, we undertake a systematic study of conformal invariance in one-dimensional sigma models where an isometry group has been gauged.

Programmable Reconfiguration of Hybrid 4D Chiral Metamaterials via Mechanical and Thermal Stimuli
Advanced Engineering Materials, EarlyView.A class of hybrid chiral mechanical metamaterials is designed to achieve programmable reconfiguration through soft networks, hinges, and bilayer joints integrated with rigid units. Responsive to mechanical and thermal stimuli, these structures exhibit large volume changes, tunable deformation pathways, and both positive and negative thermal expansion ...

RG flows and stability in defect field theories
Journal of High Energy Physics, 2023 We investigate defects in scalar field theories in four and six dimensions in a double-scaling (semiclassical) limit, where bulk loops are suppressed and quantum effects come from the defect coupling. We compute β-functions up to four loops and find that

Conformal symmetry in non-local field theories
, 2011 We have shown that a particular class of non-local free field theory has conformal symmetry in arbitrary dimensions. Using the local field theory counterpart of this class, we have found the Noether currents and Ward identities of the translation ...

Possible Central Extensions of Non-Relativistic Conformal Algebras in 1+1 [PDF]
, 2014 We investigate possibility of central extension for non-relativistic conformal algebras in 1+1 dimension. Three different forms of charges can be suggested.

Scale Invariance with a Universal Minimal Length Scale in Cosmology [PDF]
, 2018 At the heart of the issue of quantizing general relativity lies the puzzling question of defining a version of space-time diffeomorphisms compatible with the Planck length $\ell_{P}$.

Advanced Functional Materials, EarlyView.PBTTT‐OR‐R, a C14‐alkoxy/alkyl‐PBTTT polymer derivative, is of substantial interest for optoelectronics due to its specific fullerene intercalation behavior and enhanced charge‐transfer absorption. Comparing this polymer with (S) and without (O) homocoupling defects reveals that PBTTT‐OR‐R(O) forms stable co‐crystals with PC61BM, while PBTTT‐OR‐R(S ...

Fermions in boundary conformal field theory: crossing symmetry and E-expansion
Journal of High Energy Physics, 2023 We use the equations of motion in combination with crossing symmetry to constrain the properties of interacting fermionic boundary conformal field theories.

Ageing, dynamical scaling and conformal invariance
, 2003 Building on an analogy with conformal invariance, local scale transformations consistent with dynamical scaling are constructed. Two types of local scale invariance are found which act as dynamical space-time symmetries of certain non-local free field ...

Field Theory on Newton-Cartan Backgrounds and Symmetries of the Lifshitz Vacuum [PDF]
, 2015 Holography for Lifshitz space-times corresponds to dual field theories on a fixed torsional Newton-Cartan (TNC) background. We examine the coupling of non-relativistic field theories to TNC backgrounds and uncover a novel mechanism by which a global U(1)
