On The Physical Parity Transformation And Antiparticles
, 2017 It was argued a long time ago by T.D. Lee and G.C. Wick that there is a basis where the usual CP (charge-parity) transformation becomes a parity transformation. Indeed, at the quantum level all fields are real representations of the group of symmetries, because CP (charge-parity) is a linear transformation.

Halide‐Exchange Arrest Enables Reabsorption‐Free CsPbCl3/CsPbI3 Perovskite Core/Shell Nanocrystals
Advanced Science, EarlyView.Achieving large Stokes shifts in perovskite nanocrystals is challenging due to halide mobility that disrupts stable core–shell structures. Using CdCl2 passivation, this work stabilizes CsPbCl3/CsPbI3 heterostructures, yielding a ≈1.2 eV Stokes shift, high quantum yield, and fast exciton transfer, enabling reabsorption‐free emitters for advanced ...

Revisiting R-parity violating interactions as an explanation of the B-physics anomalies
European Physical Journal C: Particles and Fields, 2018 In the last few years, the ratios $$R_{D^{(*)}}$$ RD(∗) and of $$R_{K^{(*)}}$$ RK(∗) have reportedly exhibited significant deviations from the relevant standard model predictions, hinting towards a possible violation of Lepton Flavor Universality and a ...

Advanced Science, EarlyView.We combine altermagnet with topological insulators and subject the structure to Floquet driving. This breaks time‐reversal symmetry and creates a new type of higher‐order topological insulator. Its key feature is the emergence of programmable “0/π‐corner modes” that can be controlled by magnetic field direction, offering a novel dynamic platform for ...

Conformal Reconfigurable Intelligent Surfaces: A Cylindrical Geometry Perspective
Advanced Electronic Materials, EarlyView.Cylindrical reconfigurable intelligent surfaces are explored for low‐complexity beam steering using one‐bit meta‐atoms. A multi‐level modeling approach, including optimization‐based synthesis, demonstrates that even minimal hardware can support directive scattering.

New constraints on R-parity breaking from neutrino physics
Nuclear Physics B, 1992 Abstract We present a general analysis of the contraints derived from neutrino physics on explicit R -parity breaking in supersymmetric models. We consider bounds coming from (i) neutrino oscillations, (ii) neutrinoless double beta decay and (iii) neutrino cosmology and astrophysics.

Advanced Energy Materials, EarlyView.This review highlights the use of atomic layer deposition (ALD) for fabricating thermoelectric thin films with atomic‐scale control. Four material classes—chalcogenides, doped oxides, ternary oxides, and multilayered structures—are compared in terms of growth dynamics, structure–property relationships, and thermoelectric performance. The precise tuning

Advanced Energy Materials, EarlyView.A physical framework is developed based on drift‐diffusion simulations to elucidate the operation of integrated perovskite/organic solar cells (I‐POSCs) through the lens of interfacial charge‐carrier dynamics. A stepwise analysis establishes key links between carrier transport/recombination phenomena and device performance metrics, offering valuable ...
