Relaxation dynamics in an isolated long-range Ising chain
H. T. Ng, Jing-Ning Zhang
We consider a chain of trapped ions to interact with each other via long-range interactions. This system can be used to simulate the long-range Ising model. We study the dynamics o…
Decoherence of interacting Majorana modes
H. T. Ng
We study the decoherence of Majorana modes of a fermion chain, where the fermions interact with their nearest neighbours. We investigate the effect of dissipation and dephasing on…
Quantum estimation of magnetic-field gradient using W-state
H. T. Ng, K. Kim
We study the precision limits of detecting a linear magnetic-field gradient by using W-states in the presence of different types of noises. We consider to use an atomic spin chain…
Particle-hole entanglement of ultracold atoms in an optical lattice
H. T. Ng
We study the ground state of two-component bosonic atoms in a one-dimensional optical lattice. By applying an external field to the atoms at one end of lattice, the atoms are trans…
Quantum-limited measurement of magnetic-field gradient with entangled atoms
H. T. Ng
We propose a method to detect the microwave magnetic-field gradient by using a pair of entangled two-component Bose-Einstein condensates. We consider the two spatially separated co…
Coherent control of atomic spin currents in a double well
H. T. Ng, Shih-I Chu
We propose an experimental feasible method for controlling the atomic currents of a two-component Bose-Einstein condensate in a double well by applying an external field to the ato…
