Precise Photon Arrival Time Measurement via Time to Frequency Demultiplexing
Usman Khan, Santosh Kumar, Daniel Lopez +3
We demonstrate a nonlinear-optics approach to precise measurement of photon arrival time, by translating the temporal information of single photons to a wavelength distribution of…
Random matrix ensembles: Wang-Landau algorithm for spectral densities
Santosh Kumar
We propose a method based on the Wang-Landau algorithm to numerically generate the spectral densities of random matrix ensembles. The method employs Dyson's log-gas formalism for r…
Spectral statistics of interpolating random circulant matrix and its applications to random circulant graphs
Sunidhi Sen, Himanshu Shekhar, Santosh Kumar
We consider a versatile matrix model of the form , where and are real random circulant matrices with independent but, in general, nonidentica…
Layered semiconductors integrated with polyimide thin films for high-quality valleytronic and quantum-photonic systems
Jithin T Surendran, Indrajeet D Prasad, Kenji Watanabe +2
Dielectric integration of layered semiconductors is a prerequisite for fabricating high-quality optoelectronic, valleytronic, and quantum-photonic devices. While hexagonal boron ni…
Query Processing Performance and Searching Over Encrypted Data By Using An Efficient Algorithm
Manish Sharma, Atul Chaudhary, Santosh Kumar
Data is the central asset of today's dynamically operating organization and their business. This data is usually stored in database. A major consideration is applied on the securit…
Distribution of Scattering Matrix Elements in Quantum Chaotic Scattering
Santosh Kumar, André Nock, Hans-Jürgen Sommers +5
Scattering is an important phenomenon which is observed in systems ranging from the micro- to macroscale. In the context of nuclear reaction theory the Heidelberg approach was prop…
