The physics of quantum materials is dictated by many-body interactions and mathematical
concepts such as symmetry and topology that have transformed our understanding of matter …

New developments in superconductivity, particularly through unexpected and often
surprising forms of superconducting materials, continue to excite the community and …

Realistic description of competing phases in complex quantum materials has proven
extremely challenging. For example, much of the existing density-functional-theory-based …

The recent observation of the light-induced superconducting (SC)-like transient response in
c-axis optical conductivity far above the SC transition temperature T c in underdoped Y Ba 2 …

Over the past two decades, advances in computational algorithms have revealed a curious
property of the two-dimensional Hubbard model (and related theories) with hole do**: the …

Symmetry-breaking orders can not only compete with each other, but also be intertwined,
and the intertwined topological and symmetry-breaking orders make the situation more …

To decipher the mechanism of high-temperature superconductivity, it is important to know
how the superconducting pairing emerges from the unusual normal states of cuprate …

The classification of structural phase transitions as displacive or order-disorder in character
is usually based on spectroscopic data above the transition. We use single crystal x-ray …

The origin of the pseudogap behavior, found in many high-T c superconductors, remains
one of the greatest puzzles in condensed matter physics. One possible mechanism is …

We present a method to treat the two-dimensional (2D) Hubbard model for parameter
regimes which are relevant for the physics of the high-T c superconducting cuprates. Unlike …
