Many things in the natural world are geometrically chiral, meaning they cannot be superimposed onto their mirror image. Think hands — right and left hands are mirror images but if you transplanted a r...
Overcoming the slowing down of flat-histogram Monte Carlo simulations: Cluster updates and optimized broad-histogram ensembles
Monte carlo simulation energy d ferromagnetic ising model

2014/12/20
We study the performance of Monte Carlo simulations that sample a broad histogram in energy by determining the mean first-passage time to span the entire energy space of d-dimensional ferromagnetic Is...

2010/11/18
We examine different topological phases in three-dimensional non-centrosymmetric superconductors with time-reversal symmetry by using three different types of topological invariants. Due to the bulk b...

font style='font-size:12px;'>
2010/11/11
We propose a holographic correspondence of the flat spacetime based on the behavior of the entanglement entropy and the correlation functions. The holographic dual theory turns out to be highly non-lo...
