Interference effects at electron tunneling
N. Angelescu, M. Bundaru, R. Bundaru +1
Two infinite, two-dimensional, lattice, free fermion systems, initially in different invariant states, are allowed to communicate via two point contacts, through which direct tunne…
Lower Spectral Branches of a Spin-Boson Model
Nicolae Angelescu, Robert Minlos, Jean Ruiz +1
We study the structure of the spectrum of a two-level quantum system weakly coupled to a boson field (spin-boson model). Our analysis allows to avoid the cutoff in the number of bo…
Lower Spectral Branches of a Particle Coupled to a Bose Field
Nicolae Angelescu, Robert Minlos, Valentin Zagrebnov
The structure of the lower part (i.e. -away below the two-boson threshold) spectrum of Fröhlich's polaron Hamiltonian in the weak coupling regime is obtained in spatial dimensio…
On Long-Range Order in Low-Dimensional Lattice-Gas Models of Nematic Liquid Crystals
N. Angelescu, S. Romano, V. A. Zagrebnov
The problem of the orientational ordering transition for lattice-gas models of liquid crystals is discussed in the low-dimensional case . For isotropic short-range interacti…
Nematogenic Lattice Models in One or Two Dimensions and with Long-Range Interactions
N. Angelescu, S. Romano, V. A. Zagrebnov
Extending previous rigorous results, we prove existence of an ordering transition at finite temperature for a class of nematogenic lattice models, where spins are associated with a…
