Eigenstate transitions and critical transport in 3D Aubry-André model
Pragna Das, Lev Vidmar, Miroslav Hopjan
We numerically study spectral and wave-function properties, as well as time evolution, in finite-size commensurate approximations of the 3D Aubry-André model. We explicitly show, t…

Emergence of Unruh prethermalization for uniformly accelerating many-atom system
Saptarshi Saha, Chiranjeeb Singha, Pragna Das +1
A uniformly accelerated atom in an inertial vacuum generally thermalizes and reaches a Gibbs state. This phenomenon is commonly known as the Unruh effect. Here, we show that the si…

A detailed study on various phases in dissipative anisotropic Dicke model
Pragna Das, Saptarshi Saha
We present a comprehensive study of different phases in the Dicke model incorporating both anisotropy and dissipation. We begin with a concise review of the quantum phase transitio…
