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…

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…
