Discrete Time Crystals with Absolute Stability
Krzysztof Giergiel, Jia Wang, Bryan J. Dalton +2
We show that interacting bosons on a ring which are driven periodically by a rotating potential can support discrete time crystals whose absolute stability can be proven. The absol…
Mesoscopic two-mode entangled and steerable states of 40,000 atoms in a Bose-Einstein condensate interferometer
B. Opanchuk, L. Rosales-Zárate, R. Y. Teh +4
Using criteria based on superselection rules, we analyze the quantum correlations between the two condensate modes of the Bose-Einstein condensate interferometer of Egorov et al. […
The Symmetry Group Paradox for Non-Rigid Molecules
B. J. Dalton
In many situations the energy levels for a quantum system whose Hamiltonian is invariant under a specific symmetry group are split when the Hamiltonian is replaced by a new one wit…
Quantum Entanglement for Systems of Identical Bosons. I General Theory
Bryan Dalton, John Goold, Barry Garraway +1
These two accompanying papers treat two mode entanglement for systems of identical massive bosons and the relationship to spin squeezing and other quantum correlation effects. Enta…
Quantum Entanglement for Systems of Identical Bosons. II Spin Squeezing and Other Entanglement Tests
Bryan Dalton, John Goold, Barry Garraway +1
These two accompanying papers treat two mode entanglement for systems of identical massive bosons and the relationship to spin squeezing and other quantum correlation effects. Enta…
New Spin Squeezing and Other Entanglement Tests for Two Mode Systems of Identical Bosons
Bryan Dalton. Libby Heaney, John Goold, Barry Garraway +1
For any quantum state representing a physical system of identical particles, the density operator must satisfy the symmetrisation principle (SP) and for massive particles also conf…
Cascade atom in high-Q cavity: The spectrum for non-Markovian decay
B. J. Dalton, B. M. Garraway
The spontaneous emission spectrum for a three level cascade configuration atom in a single mode high-Q cavity coupled to a zero temperature reservoir of continuum external modes is…
Theory of decoherence in Bose-Einstein condensate interferometry
B J Dalton
A full treatment of decoherence and dephasing effects in BEC interferometry has been developed based on using quantum correlation functions for treating interferometric effects. Th…
Theory of non-Markovian decay of a cascade atom in high-Q cavities and photonic band-gap materials
B. M. Garraway, B. J. Dalton
The dynamics of a three-level atom in a cascade configuration with both transitions coupled to a single structured reservoir of quantized field modes is treated using Laplace trans…
Two-Mode Theory of BEC Interferometry
B J Dalton
A theory of BEC interferometry in an unsymmetrical double-well trap has been developed for small boson numbers, based on the two-mode approximation. The bosons are initially in the…
Decoherence Rates in Large Scale Quantum Computers and Macroscopic Systems
B J Dalton
Markovian regime decoherence effects in quantum computers are studied in terms of the fidelity for the situation where the number of qubits N becomes large. A general expression gi…
Theory of Pseudomodes in Quantum Optical Processes
B. J. Dalton, S. M. Barnett, B. M. Garraway
This paper deals with non-Markovian behaviour in atomic systems coupled to a structured reservoir of quantum EM field modes, with particular relevance to atoms interacting with the…
