Spectroscopic characterization and mechanistic studies on visible light photoredox carbon–carbon bond formation by bis(arylimino)acenaphthene copper photosensitizers
(2018)Currently, the most popular molecular photosensitizers used for synthetic organic chemistry and energy applications are still the noble metalbased ruthenium and iridium complexes that usually require expensive metal and ... 
拉盖尔高斯光束照射产生散斑场的特性研究 = Study on properties of speckle field formed by LaguerreGaussian beam illumination
(2015)研究了拉盖尔高斯光束照射毛玻璃产生的散斑场的特性。利用空间光调制器结合计算全息法产生了拉盖尔高斯涡旋光束；较深入地研究了拉盖尔高斯光束照射下散斑大小与光束径向指数、角向指数及涡旋光束面积间的关系。结果显示：对同一径向指数，散斑颗粒平均大小随角向指数的增大呈直线减小趋势；对同一角向指数，散斑大小随径向指数的增大而减小；散斑大小与涡旋光束照射面积的负指数成正比；随径向指数的增大，其逐渐接近高斯光束照射的结果。 The properties ... 
Large dimensional empirical likelihood
(2015)The empirical likelihood is a versatile nonparametric approach to testing hypotheses and constructing confidence regions. However it is not clear if Wilks’ Theorem still works in high dimensions. In this paper, by adding ... 
Correlation in hard distributions in communication complexity
(2015)We study the effect that the amount of correlation in a bipartite distribution has on the communication complexity of a problem under that distribution. We introduce a new family of complexity measures that interpolates ... 
Spin response to localized pumps : exciton polaritons versus electrons and holes
(2016)Polariton polarization can be described in terms of a pseudospin which can be oriented along the x,y, or z axis, similarly to electron and hole spin. Unlike electrons and holes where timereversal symmetry requires that ... 
Embeddings of Schatten norms with applications to data streams
(2017)Given an n×d matrix A, its Schattenp norm, p >= 1, is defined as A_p = (sum_{i=1}^rank(A) sigma(i)^p）^{1/p} where sigma_i(A) is the ith largest singular value of A. These norms have been studied in functional ... 
Ultrastrong lightmatter coupling of cyclotron transition in monolayer MoS2
(2016)The lightmatter coupling between cyclotron transition and photon is theoretically investigated in a monolayer MoS2 system with consideration of the influence of electronhole asymmetry. The results show that ultrastrong ... 
Superconducting resonator and Rydberg atom hybrid system in the strong coupling regime
(2016)We propose a promising hybrid quantum system, where a highly excited atom strongly interacts with a superconducting LC oscillator via the electric field of capacitor. An external electrostatic field is applied to tune the ... 
Quantum statistics in a timemodulated excitonphoton system
(2016)We consider a system consisting of a large individual quantum dot with excitonic resonance coupled to a singlemode photonic cavity in the nonlinear regime when excitonexciton interaction becomes important. Quantum ... 
Thermodynamical cost of some interpretations of quantum theory
(2016)The interpretation of quantum theory is one of the longeststanding debates in physics. Type I interpretations see quantum probabilities as determined by intrinsic properties of the observed system. Type II see them as ... 
Power of one qumode for quantum computation
(2016)Although quantum computers are capable of solving problems like factoring exponentially faster than the bestknown classical algorithms, determining the resources responsible for their computational power remains unclear. ... 
Power of one bit of quantum information in quantum metrology
(2016)We present a model of quantum metrology inspired by the computational model known as deterministic quantum computation with one quantum bit (DQC1). Using only one pure qubit together with l fully mixed qubits we obtain ...

Polariton laser diodes
(2014)Excitonpolariton lasers are operated in the strong light matter coupling regime. They promise low threshold operation since population inversion is not inherently necessary. Hence they are of great interest for next ... 
Bayregion functionalisation of ArBIAN ligands and their use within highly absorptive cationic iridium(III) dyes
(2017)We report the synthesis, UVvis absorption, electrochemical characterisation, and DFT studies of five panchromatic, heteroleptic iridium complexes (four of which are new) supported by ArBIAN ligands. In particular, the ...
