Quantum thermodynamics for a model of an expanding universe
Nana Liu, John Goold, Ivette Fuentes +3
We investigate the thermodynamical properties of quantum fields in curved spacetime. Our approach is to consider quantum fields in curved spacetime as a quantum system undergoing a…
Motion and gravity effects in the precision of quantum clocks
Joel Lindkvist, Carlos Sabín, Göran Johansson +1
We show that motion and gravity affect the precision of quantum clocks. We consider a localised quantum field as a fundamental model of a quantum clock moving in spacetime and show…
Quantum estimation of the Schwarzschild space-time parameters of the Earth
David Edward Bruschi, Animesh Datta, Rupert Ursin +2
We propose a quantum experiment to measure with high precision the Schwarzschild space-time parameters of the Earth. The scheme can also be applied to measure distances by taking i…
Effects of three-body collisions in a two-mode Bose-Einstein condenstate
Carlos Sabín, Pablo Barberis-Blostein, Cristopher Hernández +2
We study the effects of three-body collisions in the basic physical properties of a two-mode Bose-Einstein condensate. By finding the exact analytical solution of a model which inc…
Analytical solution of a double-well Bose-Einstein Condensate
Carlos Sabín, Pablo Barberis-Blostein, Ivette Fuentes
We introduce a microscopic computation which shows that the Hamiltonian of a Bose-Einstein Condensate can be analytically solved in the two-mode approximation, in particular, in th…
Analog quantum simulation of gravitational waves in a Bose-Einstein condensate
Tupac Bravo, Carlos Sabín, Ivette Fuentes
We show how to vary the physical properties of a Bose-Einstein condensate (BEC) in order to mimic an effective gravitational-wave spacetime. In particular, we focus in the simulati…
