Gravitational waves from first-order cosmological phase transitions: lifetime of the sound wave source
John Ellis, Marek Lewicki, José Miguel No
We survey systematically the general parametrisations of particle-physics models for a first-order phase transition in the early universe, including models with polynomial potentia…
Oscillation probabilities for a PT-symmetric non-Hermitian two-state system
Jean Alexandre, Madeleine Dale, John Ellis +2
There is growing interest in viable quantum theories with PT-symmetric non-Hermitian Hamiltonians, but a formulation of transition matrix elements consistent with positivity and pe…
STE-QUEST -- Space Time Explorer and QUantum Equivalence principle Space Test: The 2022 medium-class mission concept
Naceur Gaaloul, Holger Ahlers, Leonardo Badurina +45
Space-borne quantum technologies, particularly those based on atom interferometry, are heralding a new era of strategic and robust space exploration. The unique conditions of space…
