Critical line of the triangular Ising antiferromagnet in a field from a C3-symmetric corner transfer matrix algorithm

Frédéric Mila, Jeanne Colbois, Samuel Louis Nyckees, Afonso Dos Santos Rufino

The corner transfer matrix renormalization group (CTMRG) algorithm has been extensively used to investigate both classical and quantum two-dimensional (2D) lattice models. The convergence of the algorithm can strongly vary from model to model depending on ...

Impact of heterocirculene molecular symmetry upon two-dimensional

Despite the development of crystal engineering, it remains a great challenge to predict the crystal structure even for the simplest molecules, and a clear link between molecular and crystal symmetry is missing in general. Here we demonstrate that the two-d ...

Analysis of the low-frequency spectrum of the cubic noncentrosymmetric ferrimagnet Cu2OSeO3

Helmuth Berger

The IR reflectance spectra of the cubic noncentrosymmetric ferrimagnet Cu2OSeO3 (T-C approximate to 60 K) were investigated in the temperature range 10-80 K. Detailed analysis of the symmetry and composition of vibrational modes was conducted on the basis ...

Symmetry Elevation and Symmetry Breaking: Keys to Describe and Explain Excitonic Complexes in Semiconductor Quantum Dots

Elyahou Kapon, Alok Rudra, Marc-André Dupertuis, Daniel Oberli

The results of a group theoretical analysis of the excitonic fine structure are presented and compared with spectroscopic data on single quantum dots. The spectral features reveal the signatures of a symmetry higher than the crystal symmetry (C-3v). A cons ...

Influence of Subsurface Layers on the Adsorption of Large Organic Molecules on Close-Packed Metal Surfaces

Klaus Kern

The asymmetric molecule 4-[trans-2-(pyrid-4-yl-vinyl)] benzoic acid (PVBA) adsorbed on Cu(111) is characterized by scanning tunneling microscopy (STM) and density functional theory (DFT) to determine the influence of subsurface atomic layers on the adsorpt ...

Molecular Properties Determined from Relaxation of Long-Lived Spin States

Geoffrey Bodenhausen, Riddhiman Sarkar, Paul Romeo Vasos, Puneet Ahuja

The populations of long-lived spin states, in particular, populations of singlet states that are comprised of antisymmetric combinations of product states, ∣αIβS⟩−∣βIαS⟩, are characterized by very long lifetimes because the dipole-dipole interaction betwee ...

Polymorphism in micro-, submicro-, and nanocrystalline NaNbO3

Arnaud Magrez

NaNbO3 powders with various particle sizes (ranging from 30 nm to several microns) and well-controlled stoichiometry were obtained through microemulsion-mediated synthesis. The effect of particle size on the phase transformation of the prepared NaNbO3 Powd ...
