Cavity-induced emergent topological spin textures in a Bose Einstein condensate
Stefan Ostermann, Hon-Wai Lau, Helmut Ritsch +1
The coupled nonlinear dynamics of ultracold quantum matter and electromagnetic field modes in an optical resonator exhibits a wealth of intriguing collective phenomena. Here we stu…
Chimera patterns in conservative systems and ultracold atoms with mediated nonlocal hopping
Hon Wai Lau, Jörn Davidsen, Christoph Simon
Experimental realizations of chimera patterns, characterized by coexisting regions of phase coherence and incoherence, have so far only been achieved for non-conservative systems w…
Linked and knotted chimera filaments in oscillatory systems
Hon Wai Lau, Jörn Davidsen
While the existence of stable knotted and linked vortex lines has been established in many experimental and theoretical systems, their existence in oscillatory systems and systems…
Large Energy Superpositions via Rydberg Dressing
Mohammadsadegh Khazali, Hon Wai Lau, Adam Humeniuk +1
We propose to create superposition states of over 100 Strontium atoms being in a ground state or metastable optical clock state, using the Kerr-type interaction due to Rydberg stat…
Strong micro-macro entanglement from a weak cross-Kerr nonlinearity
Tian Wang, Hon Wai Lau, Hamidreza Kaviani +2
We study the entanglement generated by a weak cross-Kerr nonlinearity between two initial coherent states, one of which has an amplitude close to the single-photon level, while the…
Proposal for the Creation and Optical Detection of Spin Cat States in Bose-Einstein Condensates
Hon Wai Lau, Zachary Dutton, Tian Wang +1
We propose a method to create "spin cat states", i.e. macroscopic superpositions of coherent spin states, in Bose-Einstein condensates using the Kerr nonlinearity due to atomic col…
Information theoretic aspects of the two-dimensional Ising model
Hon Wai Lau, Peter Grassberger
We present numerical results for various information theoretic properties of the square lattice Ising model. First, using a bond propagation algorithm, we find the difference $2H_L…
Agglomerative Percolation on Bipartite Networks: A Novel Type of Spontaneous Symmetry Breaking
Hon Wai Lau, Maya Paczuski, Peter Grassberger
Ordinary bond percolation (OP) can be viewed as a process where clusters grow by joining them pairwise, by adding links chosen randomly one by one from a set of predefined `virtual…
Detection of network inhomogeneity by total neighbor degree
H. W. Lau, K. Y. Szeto
Inhomogeneity in networks can be detected by the analysis of the correlation of the total degree of nearest neighbors. This is illustrated by two models. The first one is a random…
Asymptotic analysis of first passage time in complex networks
Hon Wai Lau, Kwok Yip Szeto
The first passage time (FPT) distribution for random walk in complex networks is calculated through an asymptotic analysis. For network with size and short relaxation time $τ\l…
