A dynamical systems perspective on the thermodynamics of late-time cosmology
Dipayan Mukherjee, Harkirat Singh Sahota, Swati Gavas
A thermodynamic description of cosmological spacetimes may provide insights into the fundamentals of the cosmic evolution that remain otherwise obscure, similar to `black hole ther…
Quantum Cosmology as a Hydrogen atom: Discrete and cyclic Universes from Wheeler-DeWitt quantization
Dipayan Mukherjee, Harkirat Singh Sahota, S. Shankaranarayanan
Building upon our recently established correspondence between quantum cosmology and the hydrogen atom [1], we investigate the specific sector of a negative cosmological constant ($…
V(is)owel: An Interactive Vowel Chart to Understand What Makes Visual Pronunciation Effective in Second Language Learning
Charlotte Kiesel, Dipayan Mukherjee, Mark Hasegawa-Johnson +1
Visual feedback speeds up learners' improvement of pronunciation in a second language. The visual combined with audio allows speakers to see sounds and differences in pronunciation…
Unitary quantum matter-bounce in a universe with a positive cosmological constant
Harkirat Singh Sahota, Dipayan Mukherjee, S. Shankaranarayanan
We analyze the Wheeler-DeWitt quantization of a spatially flat Friedmann-Lemaître-Robertson-Walker universe containing pressureless dust and a positive cosmological constant ($Λ> 0…
