Superconductivity of repulsive spinless fermions with sublattice potentials
Yuchi He, Kang Yang, Jonas B. Profe +2
We explore unconventional superconductivity of repulsive spinless fermions on square and honeycomb lattices with staggered sublattice potentials. The two lattices can exhibit stagg…
Quantum Metric Induced Phases in Moiré Materials
Ahmed Abouelkomsan, Kang Yang, Emil J. Bergholtz
We show that, quite generally, quantum geometry plays a major role in determining the low-energy physics in strongly correlated lattice models at fractional band fillings. We ident…
Exceptional dynamics of interacting spin liquids
Kang Yang, Daniel Varjas, Emil J. Bergholtz +2
We show that interactions in quantum spin liquids can result in non-Hermitian phenomenology that differs qualitatively from mean-field expectations. We demonstrate this in two prom…
Seven-coordinated Silicon in a SiO2He Compound Formed under the Extreme Conditions of Planetary Interiors
Shicong Ding, Pan Zhang, Kang Yang +5
Changes in atomic coordination numbers at high pressures are fundamental to condensed-matter physics because they initiate the emergence of unexpected structures and phenomena. Sil…
Helium Incorporation Stabilized Direct-gap Silicides
Shicong Ding, Jingming Shi, Jiahao Xie +8
The search of direct-gap Si-based semiconductors is of great interest due to the potential application in many technologically relevant fields. This work examines the incorporation…
