Space-time from collapse of the wave-function
Tejinder P. Singh
We propose that space-time results from collapse of the wave function of macroscopic objects, in quantum dynamics. We first argue that there ought to exist a formulation of quantum…
Testing the limits of quantum mechanics
Tejinder P. Singh
A brief non-technical account of the current status of collapse models.
Path integrals, spontaneous localisation, and the classical limit
Bhavya Bhatt, Manish Ram Chander, Raj Patil +3
We recall that in order to obtain the classical limit of quantum mechanics one needs to take the limit. In addition, one also needs an explanation for the abse…
Testing spontaneous collapse through bulk heating experiments: estimate of the background noise
Ruchira Mishra, Andrea Vinante, Tejinder P. Singh
Models of spontaneous wave function collapse predict a small heating rate for a bulk solid, as a result of coupling to the noise field that causes collapse. This rate is small enou…
Space and time as a consequence of GRW quantum jumps
Tejinder P. Singh
The Ghirardi-Rimini-Weber (GRW) theory of spontaneous collapse offers a possible resolution of the quantum measurement problem. In this theory, the wave function of a particle spon…
Einstein-Cartan-Dirac equations in the Newman-Penrose formalism
Swanand Khanapurkar, Abhinav Varma, Nehal Mittal +2
We formulate the Einstein-Cartan-Dirac equations in the Newman-Penrose (NP) formalism, thereby presenting a more accurate and explicit analysis of previous such studies. The equati…
