In this brief review, we introduce a new spin ladder system called skewed spin ladders and
discuss the exotic quantum phases of this system. The spin ladders studied are the 5/7, 3/4 …

Abstract Model Hamiltonians have been, and still are, a valuable tool for investigating the
electronic structure of systems for which mean field theories work poorly. This review will …

Highly doped organic polymers have emerged as prominent candidates within novel
technological disciplines, yet the fundamental correlation between structure and charge …

Using spin-unrestricted density functional theory, the longitudinal static second
hyperpolarizability γ has been investigated for an asymmetric azulene-like open-shell …

The renaissance of multiferroics has yielded a deeper understanding of magneto-electric
coupling of inorganic single-phase multiferroics and composites. Here, we report charge …

Combining the roles of spin frustration and geometry of odd and even numbered rings in
polyaromatic hydrocarbons (PAHs), we design small molecules that show exceedingly small …

The quantum phases of two-leg spin-1 2 ladders with skewed rungs are obtained using
exact diagonalization of systems with up to 26 spins and by density-matrix renormalization …

Covalent triazine frameworks (CTFs) are among the most valuable frameworks owing to
many fantastic properties. However, molten salt‐involved preparation of CTFs at 400–600° …

Magnetization plateaus are some of the most striking manifestations of frustration in low-
dimensional spin systems. We present numerical studies of magnetization plateaus in the …

The spin-1/2 transverse field two-leg Ising ladder with nearest-neighbor exchange and
plaquette four-spin interaction J 4 is studied analytically and numerically with the density …
