• Cyclotomy and Ramanujan sums in quantum phase locking 

      Planat, Michel; Rosu Barbus, Haret-Codratian (2003)
      "Phase-locking governs the phase noise in classical clocks through effects described in precise mathematical terms. We seek here a quantum counterpart of these effects by working in a finite Hilbert space. We use a coprimality ...
    • On arithmetic detection of grey pulses with application to Hawking radiation 

      Rosu Barbus, Haret-Codratian; Planat, Michel (2002)
      "Micron-sized black holes do not necessarily have a constant horizon temperature distribution. The black hole remote-sensing problem means to find out the "surface" temperature distribution of a small black hole from the ...
