Strongly bound excitons determine light–matter interactions in van der Waals
heterostructures of two-dimensional semiconductors. Unlike fundamental particles …

Carbon is one of the most interesting chemical elements. It not only forms the basis of the
vast kingdom of organic substances but itself forms various crystals and nanostructures. This …

The condensation of excitons into an electron–hole liquid (EHL) and the main EHL
properties in bulk semiconductors and low-dimensional structures are considered. The EHL …

We propose experiments to observe Bose-Einstein condensation and superfluidity of quasi-
two-dimensional spatially indirect magnetoexcitons in two-layer graphene. The energy …

Графен представляет собой двумерную структуру, составленную из атомов углерода,
которые расположены в узлах кристаллической решетки типа пчелиные соты и …

Abstract A one-dimensional (1D) Bose system with dipole-dipole repulsion is studied at zero
temperature by means of a quantum Monte Carlo method. It is shown that, in the limit of …

The influence of a random field induced by impurities, boundary irregularities etc. on the
superfluidity of a quasi-two-dimensional (2D) system of spatially indirect excitons in coupled …

We predict the effect of the roton instability for a two-dimensional weakly interacting gas of
tilted dipoles in a single homogeneous quantum layer. Being typical for strongly correlated …

Using a combined analytical/molecular dynamics approach, we study the current fluctuation
spectra and longitudinal and transverse collective mode dispersions of the classical two …

By doing quantum Monte Carlo ab initio simulations we show that dipolar excitons, which
are now under experimental study, actually are strongly correlated systems. Strong …
