Journal club seminar: A potential probe of quantum gravity with large molecular wavepackets

2019-11-20
TBA

Carlos Villalpando  will tell us about "A potential probe of quantum gravity with large molecular wavepackets". The talk is based on two papers:  Minimal length effect on the broadening of free wave packets and its physical implications  and Indirect Probe of Quantum Gravity using Molecular Wave-packets.

Abstract:  The biggest obstacle for a direct test of quantum gravity is its energy scale, which is well outside of the capabilites of any human-made machine; the next best possible approach then is to provide indirect tests on effective theories of quantum gravity, which can be performed in a lower energy scale. This talk will be aimed in this direction, showing a promising path to test the existence of a fundamental, minimal length scale of Nature, by measuring the dispersion of large molecular wave-packets. The existence of this minimal length would imply a modified commutation relation between position and momentum operators, and as we will see, such a modification of the commutator has a profound effect on the dispersion rate of free wave-packets, providing a path for a potential, indirect test of quantum gravity in a laboratory setting.
