Ac-Susceptibility Study in Rare Earth Substituted Magnetite Ferrofluids

Upadhyay, Ramesh V.; Parekh, Kinnari; Banerjee, A.; Kumar, Kranti (2010-08-20)

It is shown that variation of the third order ac-susceptibility as a function of measuring field and frequency lead to distinguish between superparamagnetic and spin glass like ordering in the rare earth substituted magnetic ...
All periodically-poled crystals based source of tunable, continuous-wave, single-frequency, ultraviolet radiation

Aadhi, A.; Apurv Chaitanya, N.; Singh, Ravindra P.; Samanta, Goutam Kumar (Optical Society of America, 2015-05)

We report on all periodically-poled crystals based singly-resonant optical parametric oscillator (SRO) generating continuous-wave, single-frequency, tunable UV radiation with maximum output power of 336mW in 18.5 MHz ...
Autonomous dome for a robotic telescope

Kumar, Akash; Sengupta, Anand; Ganesh, Shashikiran (2015-02)
Black hole thermodynamics: Beyond general relativity

Sarkar, Sudipta (2013-03-03)

The striking similarity of the laws of black hole mechanics with thermodynamics was first established in the case of general relativity (GR). But the Einstein-Hilbert Lagrangian of general relativity is only the lowest ...
Characterization of functional brain networks and emotional centers using the complex networks techniques

Tripathi, Richa; Mukhopadhyay, Dyutiman; Singh, Chakresh Kumar; Miyapuram, Krishna Prasad; Jolad, Shivakumar (2019-12-10)
Comparison of various synthesis methods of magnetic nanoparticles, and of the various experimental methods used for their characterization

Cho, Kuk; Parekh, Kinnari; Lee, Hyo Sook (2010-08-01)

It has been a hot issue to enhance the thermal conductivity of a fluid with nanoparticles, i.e. nanofluids. Ferrofluid is one good candidate because it has dispersion stability. Around 8 nm Mn-Zn ferrite ferrofluid was ...
Constraints on leptophilic light dark matter from internal heat flux of earth

Chauhan, Bhavesh; Mohanty, Subhendra (12-12-16)
Constraints on minimal type-III seesaw model from naturalness, lepton flavor violation, and electroweak vacuum stability

Goswami, Srubabati; Vishnudath, K. N.; Khan, Najimuddin (10-12-18)
Construction of coherent and partially coherent orbital angular momentum poincaré sphere

Chithrabhanu, P.; Aadhi, A.; Gangi Reddy, Salla; Prabhakar, Shashi; Singh, Ravindra P. (Indian Institute of Technology Kharagpur, 2014-12)

We construct Poincar´e sphere for orbital angular momentum (OAM) states for coherent and partially coherent light beams using a non-separable state generated with modified Sagnac interferometer and a random scatterer.
Continuous-variable Entanglement in Optical Vortex Beams

Prabhakar, Shashi; Salla, Gangi Reddy; Ali, Anwar M. A.; Singh, Ravindra P. (The optical society, 2014-12)

Optical vortices, although being classical, have properties of two-mode entanglement present in quantum states. We have experimentally verified the violation of Bell's inequality using Wigner distribution function for such beams.
Continuous-wave, high Power, single-frequency, tunable ultraviolet source based on all periodically poled crystals

Aadhi, A.; Apurv Chaitanya, N.; Singh, Ravindra P.; Samanta, Goutam Kumar (IIT Kharagpur, 2014-12)

We report on all periodically-poled crystals based singly-resonant optical parametric oscillator (SRO) generating continuous-wave, single-frequency, tunable UV radiation with maximum output power of 336mW in 18.5 MHz ...
Control of spatial distribution of entangled photons by the spatial structure of classical pump beam

Apurv Chaitanya, N.; Jabir, M. V.; Samanta, Goutam Kumar (Optical Society of America, 2016-10-17)
Control of spatial distribution of entangled photons by the spatial structure of classical pump beam

Jabir, M. V.; Apurv Chaitanya, N.; Samanta, Goutam Kumar (Optical Society of America, 2016-10-17)

Dark Matter in Minimal U(1)B-L Model

Basak, Tabushree; Mondal, Tanmoy (29-06-14)
Development of potent and selective inhibitors for ATR: an adjuvant for DNA damage based chemotherapeutics

Kirubakaran, Sivapriya; Thiruvenkatam, Vijay; Shaik, Althaf (American Association for Cancer Research, 2017-04-01)

Inhibition of DNA damage checkpoint and repair function has been a challenging as well a promising approach in cancer therapy. ATR kinase is one of the key mediator of DNA damage response which induces cell cycle arrest ...
