  • Holography with Incoherent Light 
    Gautam, Akanksha; T S, Athira; Naik, Dinesh N.; Narayanmurthy C.S.; Singh, Rajeev; Singh, Rakesh Kumar (Multidisciplinary Digital Publishing Institute (MDPI), 2023-03-04)
    Conventional digital holography uses the technique of combining two coherent light fields and the numerical reconstruction of the recorded hologram leads to the object amplitude and phase information. Despite significant ...
  • Imaging Incoherent Target Using Hadamard Basis Patterns † 
    Karmakar, Tanushree; Singh, Rajeev; Singh, Rakesh Kumar (Multidisciplinary Digital Publishing Institute (MDPI), 2023-03-31)
    In this paper, we present a correlation-based imaging technique in a single-pixel imaging scheme using Hadamard basis illumination. The Hadamard basis, which has the characteristics of a two-bit value {−1, 1} and sparsity ...
  • Suppression of one-dimensional weak localization by band asymmetry 
    Arora, Kartikeya; Singh, Rajeev; Hosur, Pavan (American Physical Society, 2023-08-23)
    We investigate disorder-induced localization in metals that break time-reversal and inversion symmetries through their energy dispersion, ϵk≠ϵ-k, but lack Berry phases. In the perturbative regime of disorder, we show that ...
