The intricate interplay between charge motion and magnetic order in geometrically frustrated
lattices is central for the properties of many two-dimensional quantum materials. The …

Recent realization of well-controlled quantum simulators of the triangular-lattice Fermi-
Hubbard model, including the triangular optical lattices loaded with ultracold Fermions and …

We develop an efficient numerical method for the description of a single-hole motion in the
antiferromagnetic background. The method is free of finite-size effects and allows the …

The ability to create and stack different atomically thin transition metal dichacogenide (TMD)
layers on top of each other has opened up a rich playground for exploring new and …

Tetragonal CuO (T-CuO) has attracted attention because of its structure similar to that of the
cuprates. It has been recently proposed as a compound whose study can give an end to the …

We present a numerical study of competing orders in the 1D tJ model with long-range RKKY-
like staggered spin interactions. By circumventing the constraints imposed by Mermin …

We report on new low-energy electron diffraction, scanning tunneling microscopy, and angle-
resolved photoemission spectroscopy studies of alkali-metal/Si (111) previously established …

We calculate the quasiparticle dispersion and spectral weight of the quasiparticle that results
when a hole is added to an antiferromagnetically ordered Cu O 2 plane of a cuprate …

Ab initio density-functional theory calculations, photoemission spectroscopy (PES), scanning
tunneling microscopy, and spectroscopy (STM, STS) have been used to solve the 2 3× 2 3 R …

Motivated by possible applications to the antiferromagnetic precursor of the high-
temperature superconductor Na x CoO 2. yH 2 O, we use a systematic low-energy effective …
