A Signal Analysis Framework for Unshielded Room-Temperature Magnetocardiography
Kushal Patel, Kesavaraja C, Pranab Dutta +1
Room-temperature, unshielded recording of cardiac magnetic signals has remained a significant challenge since the inception of magnetocardiography (MCG). In this work, we present a…
Magnetocardiography measurements using an optically pumped magnetometer under ambient conditions
Kushal Patel, Kesavaraja C, Pranab Dutta +1
In this work, we report the development of a rubidium-based single-beam scalar optically pumped magnetometer (OPM) and demonstrate its application in measuring human cardiac magnet…
Evaporative cooling by pulse width modulation (PWM) of optical dipole traps
S. Sagar Maurya, Joel M. Sunil, Monu Bhartiya +4
We introduce a method for cooling atoms in an optical dipole trap using pulse-width modulation (PWM) technique, without reducing the laser power of the dipole trap. The PWM techniq…
Asymmetric dynamical localization and precision measurement of BEC micromotion
S. Sagar Maurya, J. Bharathi Kannan, Kushal Patel +4
We employ a Bose Einstein Condensate (BEC) based atom-optic kicked rotor to generate an asymmetrically localized momentum distribution that depends upon initial velocity of the BEC…
