Control of localized states of itinerant electrons and their magnetic interactions
Yaxin Sun, I. S. Lobanov, Jiahao Su +2
Controlling the magnetic properties of nanosystems by an electric field offers a number of advantages for spintronics applications. Using the noncollinear Alexander-Anderson model,…
Quantum critical behavior of cuprate superconductors observed by inelastic X-ray scattering
H. Y. Huang, C. Y. Mou, A. Singh +7
Progress toward a complete understanding of cuprate superconductors has been hindered by their intricate phase diagram, potentially linked to a quantum critical point (QCP). Howeve…
Crossover in the Ordered Phase in the Non-Mermin-Wagner-Hohenberg Regime of Spin Models with Long-Range Coupling
Jiewei Ding, Jiahao Su, Ho-Kin Tang +1
Continuous spin models with long-range interactions of the form , where is the distance between two spins and controls the decay of the interaction, exhibit enhan…
Variation of Bose surface by Filling in Cooper pair Bose metal
Jiahao Su, Ji Liu, Jianyu Li +3
The Cooper pair Bose metal (CPBM) is a non-superfluid quantum phase in which uncondensed fermion pairs form a "Bose surface" in momentum space. We investigate the CPBM in the two-d…
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…
