Advanced Functional Materials, EarlyView.An asymmetric non‐fullerene acceptor BTP‐FT is developed by extending the end group of Y6‐BO with thiophene. The conformation of the molecule is determined by the noncovalent F···S interaction as demonstrated by 2D NMR and simulations. An efficiency of 18.39% is achieved in the resulting ternary solar cells processed from toluene.

On instanton effects in the operator product expansion
Journal of High Energy Physics, 2017 We revisit the computation of instanton effects to various correlation functions in N = 4 $$ \mathcal{N}=4 $$ SYM and clarify a controversy existing in the literature regarding their consistency with the OPE and conformal symmetry.

On quantum group symmetries of conformal field theories [PDF]
arXiv, 1991 The appearance of quantum groups in conformal field theories is traced back to the Poisson-Lie symmetries of the classical chiral theory. A geometric quantization of the classical theory deforms the Poisson-Lie symmetries to the quantum group ones. This elucidates the fundamental role of chiral symmetries that quantum groups play in conformal models ...

Emergent Symmetry on Black Hole Horizons
, 2013 For a stationary and axisymmetric black hole, there is a natural way to split the fields into a probe sector and a background sector. The equations of motion for the probe sector enjoy a significantly enhanced symmetry on the black hole horizon.

Conformal Symmetry and Feynman Integrals [PDF]
Proceedings of Loops and Legs in Quantum Field Theory — PoS(LL2018), 2018 Singularities hidden in the collinear region around an external massless leg may lead to conformal symmetry breaking in otherwise conformally invariant finite loop momentum integrals. For an $\ell$-loop integral, this mechanism leads to a set of linear $2$nd-order differential equations with a non-homogeneous part. The latter, due to the contact nature

Gate‐Tunable Hole Transport in In‐Plane Ge Nanowires by V‐Groove Confined Selective Epitaxy
Advanced Functional Materials, EarlyView.Ge nanowires are promising for hole spin‐based quantum processors, requiring direct integration onto Si wafers. This work introduces V‐groove‐confined selective epitaxy for in‐plane nanowire growth on Si. Structural and low‐temperature transport measurements confirm their high crystalline quality, gate‐tunable hole densities, and mobility.

Conformal mapping of non-Lorentzian geometries in SU(1, 2) Conformal Field Theory
Journal of High Energy PhysicsWe realize an explicit conformal mapping between the state and operator pictures in a class of (2 + 1)-dimensional non-Lorentzian field theories with SU(1, 2) × U(1) conformal symmetry.
