Researchers propose using Quantum Field Theory to understand singularities in general relativity, revealing that certain theoretical singularities might not affect measurable physical quantities. This could help bridge the gap between quantum physics and general relativity. One of the major issues in general...
The purpose of this work is to investigate the consequences of quantum gravity for the singularity problem. We study the higher-derivative terms that invariably appear in any quantum field theoretical model of gravity, handling them both non-perturbatively and perturbatively. In the former case, ...
The association of quantum Griffiths singularity (QGS) to the magnetic-field-induced superconductor-metal transition predicts the unconventional diverging behaviour of dynamical critical exponent in low disorder crystalline two-dimensional superconductor
quantum phase transition in two-dimensional superconductors. Here we study the magnetic field induced SMT in ultrathin crystalline Pb films down to ultralow temperatures. The divergent critical exponent is observed when approaching zero temperature quantum critical point, indicating QGS. Distinctively, the...
The technological use ofsingularitytook its name from physics. The term first came into popular use in Albert Einstein's 1915Theory of General Relativity. In the theory, a singularity describes the center of a black hole, a point of infinite density and gravity within which no object inside ca...

The well-known operator technique in quantum mechanics is used to study quantum fluctuations near the space-time singularity using Kantowski-Sachs and Bianchi type VImetrics. In both cases the wave function of the universe is found to diverge near the space-time singularity, indicating the ...
Thus, even if general relativity is assumed valid at distances less than the Planck length, quantum mechanics seems to forbid singularities in a closed FRW universe.doi:10.1023/A:1026797413078T. R. MonganPhysics
Griffith Singularity in Quantum Systems The physics of Griffiths singularity dates back to 1969, when American physicist Robert B. Griffiths proposed a type of phase transition in which the scaling invariance is broken. In this case, the critical exponent tends to diverge rather than remain constant...
