Stochastic pump of interacting particles
Debasish Chaudhuri, Abhishek Dhar
We consider the overdamped motion of Brownian particles, interacting via particle exclusion, in an external potential that varies with time and space. We show that periodic potenti…
Theory of the asymmetric ripple phase in achiral lipid membranes
Md. Arif Kamal, Antara Pal, V. A. Raghunathan +1
We present a phenomenological theory of phase transitions in achiral lipid membranes in terms of two coupled order parameters -- a scalar order parameter describing lipid chain mel…
Primordial magnetic field limits from cosmological data
Tina Kahniashvili, Alexander G. Tevzadze, Shiv K. Sethi +2
We study limits on a primordial magnetic field arising from cosmological data, including that from big bang nucleosynthesis, cosmic microwave background polarization plane Faraday…
Development of a Thomson X-ray Polarimeter
Rishin P. V., Biswajit Paul, Duraichelvan R. +3
We describe the current status of the design and development of a Thomson X-ray polarimeter suitable for a small satellite mission. Currently we are considering two detector geomet…
Heat conduction in disordered harmonic lattices with energy conserving noise
Abhishek Dhar, Joel Lebowitz, Venkateshan Kannan
We study heat conduction in a harmonic crystal whose bulk dynamics is supplemented by random reversals (flips) of the velocity of each particle at a rate . The system is maintai…
Record Statistics of Continuous Time Random Walk
Sanjib Sabhapandit
The statistics of records for a time series generated by a continuous time random walk is studied, and found to be independent of the details of the jump length distribution, as lo…
