Efficient sampling using Macrocanonical Monte Carlo and density of states mapping
Jiewei Ding, Jiahao Su, Ho-Kin Tang +1
In the context of Monte Carlo sampling for lattice models, the complexity of the energy landscape often leads to Markov chains being trapped in local optima, thereby increasing the…
p-wave superconductivity induced by nearest-neighbor attraction in the square-lattice extended Hubbard model
Zhangkai Cao, Jianyu Li, Jiahao Su +2
The two-dimensional (2D) Hubbard model is widely believed to contain the key ingredients of high-temperature superconductivity in cuprate materials. Here, we report a constrained p…
dx2-y2-wave Bose Metal induced by the next-nearest-neighbor hopping t'
Zhangkai Cao, Jianyu Li, Jiahao Su +2
Superconductivity arises when electrons form Cooper pairs with phase coherence. In contrast, a lack of phase coherence in Cooper pairs can lead to an uncondensed metallic ground st…
Exotic d-wave Cooper Pair Bose Metal in two dimensions
Zhangkai Cao, Jiahao Su, Jianyu Li +5
The study of non-Fermi liquids sheds light on unconventional phenomena in condensed matter systems that lie beyond the scope of Landau Fermi liquid theory. One intriguing example i…
