Optical cavities can induce photon-mediated interactions among intracavity-trapped atoms. Multimode cavities provide the ability to tune the form of these interactions, e.g., by inducing a nonlocal, sign-changing term to the interaction. By accountin

We observe the joint spin-spatial (spinor) self-organization of a two-component BEC strongly coupled to an optical cavity. This unusual nonequilibrium Hepp-Lieb-Dicke phase transition is driven by an off-resonant two-photon Raman transition formed fr

Optical cavity QED provides a platform with which to explore quantum many-body physics in driven-dissipative systems. Single-mode cavities provide strong, infinite-range photon-mediated interactions among intracavity atoms. However, these global all-

This paper exemplifies the design of a low profile wide-band microstrip antenna suitable for S-Band telemetry applications. The proposed design explores the concept of wide-band antenna with improved omnidirectional gain and smaller size essentially

Phase transitions, where observable properties of a many-body system change discontinuously, can occur in both open and closed systems. Ultracold atoms have provided an exemplary model system to demonstrate the physics of closed-system phase transiti

We report the first realization of a quantum degenerate mixture of bosonic $^{87}$Rb and fermionic $^{171}$Yb atoms in a hybrid optical dipole trap with a tunable, species-dependent trapping potential. $^{87}$Rb is shown to be a viable refrigerant fo

Green building research has received a lot of attention from both academicians and practitioners. Even though, this has resulted in a surge in Green Building literature in the recent times, the review of the literature has either being too focused on

The vulnerability of the tribals to lose more than the commodity value of land due to large dam projects in the North East has not been given due attention both in policy space and empirical research. Also, the question of whether the living standard

Reforming Electricity Access and End-Use Efficiency Policies in India – A Social Welfare Perspective
Publikováno v:
E3S Web of Conferences, Vol 455, p 02013 (2023)
Social welfare has been believed to be a trickle-down effect of power sector reform policies, and there have been extensive debates on whether the trickle-down happens in reality. Such perceived benefits are arguably not fully realised in an emerging
