Cumulants associated with geometric phases and their implementation in modern theory of crystalline polarization
(Bilkent University, 2022-09)Many fields have been influenced by Berry's geometric phase because of its physical meaning and observable effects. One of the breakthroughs that stem from geometric phases is the modern theory of polarization. The ... -
Exceptional adaptable MWIR thermal emission for ordinary objects covered with thin VO2 film
(Elsevier Ltd, 2021-01-25)Monotonous thermal radiation emitted from an ordinary object can be brought into a dynamic and versatile form that can be shaped according to the application area with the ingenious design of the surface coatings. Building ... -
Gibbs measures and phase transitions in various one-dimensional models
(Bilkent University, 2013)In the thesis, limiting Gibbs measures of some one dimensional models are investigated and various criterions for the uniqueness of limiting Gibbs states are considered. The criterion for models with unique ground state ... -
Ground states of one-dimensional long-range ferromagnetic ising model with external field
(World Scientific Publishing, 2012)A zero-temperature phase-diagram of the one-dimensional ferromagnetic Ising model is investigated. It is shown that at zero temperature spins of any compact collection of lattice points with identically oriented external ... -
One-dimensional long-range ferromagnetic ising model under weak and sparse external field
(2009)We consider the one-dimensional ferromagnetic Ising model with very long range interaction under weak and sparse biased external field and prove that at sufficiently low temperatures, the model has a unique limiting Gibbs ... -
The one-dimensional long-range ferromagnetic Ising model with a periodic external field
(Elsevier, 2012)We consider the one-dimensional ferromagnetic Ising model with very long-range interaction under a periodic, biased and weak external field and prove that at sufficiently low temperatures the model has a unique limiting ... -
Strain-induced structural phase transition in GeN monolayer
(Elsevier BV, 2021-11-30)The recent synthesis of SiP, SiAs, GeP, and GeAs monolayers has brought two-dimensional (2D) group IV–V systems into the limelight. To date, all the fabricated structures of this class belong to the C2/m space group which ...
