Unique Performance Considerations for Printable Organic Semiconductor and Perovskite Radiation Detectors: Toward Consensus on Best Practice Evaluation

Advanced Functional Materials, EarlyView.
A lack of standard approaches for testing and reporting the performance of metal halide perovskites and organic semiconductor radiation detectors has resulted in inconsistent interpretation of performance parameters, impeding progress in the field. This Perspective recommends key metrics and experimental details, which are suggested for reporting in ...

New R-matrices with non-additive spectral parameters and integrable models of strongly correlated fermions

Journal of High Energy Physics, 2020
We present a general formula for constructing R-matrices with non-additive spectral parameters associated with a type-I quantum superalgebra. The spectral parameters originate from two one-parameter families of inequivalent finite-dimensional irreducible

Quantum groups and functional relations for arbitrary rank

Nuclear Physics B, 2021
The quantum integrable systems associated with the quantum loop algebras Uq(L(sll+1)) are considered. The factorized form of the transfer operators related to the infinite dimensional evaluation representations is found and the determinant form of the ...

Intermolecular Interactions as Driving Force of Increasing Multiphoton Absorption in a Perylene Diimide‐Based Coordination Polymer

Advanced Functional Materials, EarlyView.
This study uncovers the unexplored role of intermolecular interactions in multiphoton absorption in coordination polymers. By analyzing [Zn2tpda(DMA)2(DMF)0.3], it shows how the electronic coupling of the chromophores and confinement in the MOF enhance two‐and three‐photon absorption.

Quantum Deformations and Superintegrable Motions on Spaces with Variable Curvature

Symmetry, Integrability and Geometry: Methods and Applications, 2007
An infinite family of quasi-maximally superintegrable Hamiltonians with a common set of (2N-3) integrals of the motion is introduced. The integrability properties of all these Hamiltonians are shown to be a consequence of a hidden non-standard quantum sl(

Generalized Buchdahl equations as Lie–Hamilton systems from the 'book' and oscillator algebras: quantum deformations and their general solution

AIMS Mathematics
We revisit the nonlinear second-order differential equations $ \ddot{x}(t) = a (x)\dot{x}(t)^2+b(t)\dot{x}(t), $ where $ a(x) $ and $ b(t) $ are arbitrary functions on their argument from the perspective of Lie–Hamilton systems.

Symmetry Groups, Quantum Mechanics and Generalized Hermite Functions

Mathematics, 2022
This is a review paper on the generalization of Euclidean as well as pseudo-Euclidean groups of interest in quantum mechanics. The Weyl–Heisenberg groups, Hn, together with the Euclidean, En, and pseudo-Euclidean Ep,q, groups are two families of groups ...

The Quantum Symplectic Cayley-Klein Groups

, 1996
The contraction method applied to the construction of the nonsemisimple quantum symplectic Cayley-Klein groups $ Fun(Sp_q(n;j)) $. This groups has been realised as Hopf algebra of the noncommutative functions over the algebra with nilpotent generators ...

Advancing Electronic Application of Coordination Solids: Enhancing Electron Transport and Device Integration via Surface‐Mounted MOFs (SURMOFs)

Advanced Functional Materials, EarlyView.
The layer‐by‐layer (LbL) assembly of coordination solids, enabled by the surface‐mounted metal‐organic framework (SURMOF) platform, is on the cusp of generating the organic counterpart of the epitaxy of inorganics. The programmable and sequential SURMOF protocol, optimized by machine learning (ML), is suited for accessing high‐quality thin films of ...

Semidual Kitaev lattice model and tensor network representation

Journal of High Energy Physics, 2021
Kitaev’s lattice models are usually defined as representations of the Drinfeld quantum double D(H) = H ⋈ H *op, as an example of a double cross product quantum group.
