Vector valued de Branges spaces, CNU contractions and functional models
Bharti Garg, Santanu Sarkar
In this paper, we study vector valued de Branges spaces associated with a de Branges operator, defined as a pair of Fredholm operator valued analytic functions on a domain symmetri…
Composition operators on de Branges spaces of entire functions
Bharti Garg, Subhankar Mahapatra, Santanu Sarkar
This paper aims to study the boundedness and compactness of composition operators from model spaces to the Hardy Hilbert spaces in the upper half-plane. Consequently, we investigat…
Plasmon exciton coupling enhances second order nonlinear response in borophene ZnO hybrid structures
Maximilian Black, Yaser Abdi, Prabhdeep Singh +7
Nonlinear optical processes in low dimensional materials are often weak or symmetry forbidden, limiting their use in nanoscale light sources and on chip frequency conversion. Here,…
J-contractive operator valued functions, vector valued de Branges spaces and functional models
Bharti Garg, Santanu Sarkar
The aim of this paper is to study the vector valued de Branges spaces, which are based on -contractive operator valued analytic functions, and to explore their role in the funct…
