Phase matching in -barium borate crystals for spontaneous parametric down-conversion
Suman Karan, Shaurya Aarav, Homanga Bharadhwaj +5
Spontaneous parametric down-conversion (SPDC) is the most widely used process for generating entangled photon pairs. In SPDC, a pump photon interacts with a nonlinear optical cryst…
Atomic switch for control of heat transfer in coupled cavities
Nilakantha Meher, S. Sivakumar
Controlled heat transfer and thermal rectification in a system of two coupled cavities connected to thermal reservoirs are discussed. Embedding a dispersively interacting two-level…
Nonintegrability and quantum fluctuations in a quantum optical model
Nilakantha Meher, S. Sivakumar
Integrability in quantum theory has been defined in more than one ways. Recently, Braak suggested a new definition that a quantum system is integrable if the number of parameters r…
Number state filtered coherent state
Nilakantha Meher, S. Sivakumar
Number state filtering in coherent states leads to sub-Poissonian photon statistics. These states are more suitable for phase estimation when compared with the coherent states. Non…
