Study of the possibility of diamond formation at moderate pressures and temperatures [PDF]
Физико-химические аспекты изучения кластеров, наноструктур и наноматериалов, 2017 Data on the diamond synthesis in experiments with carbon-saturated metal melts at moderate pressures and temperatures are presented. Features of the resulting diamond phase, the types and nature of inclusions are discussed and compared with those for ...

Antibunching Effects in the Hybrid Cavity–Bose–Einstein Condensates System
Photonics, 2023 We theoretically study the model of a hybrid cavity–Bose–Einstein condensates (BEC) system that consists of a two-level impurity atom coupled to a cavity–BEC system with radiation pressure coupling, where the system is weakly driven by a monochromatic ...

Impurity state in the vortex core of d-wave superconductors: Anderson impurity model versus unitary impurity model [PDF]
, 2002 Using an extended Anderson/Kondo impurity model to describe the magnetic moments around an impurity doped in high-$T_{\text{c}}$ d-wave cuprates and in the framework of the slave-boson meanfield approach, we study numerically the impurity state in the ...

Impurity-induced resonant states in topological nodal-line semimetals [PDF]
, 2019 Nodal-line semimetals are characterized by a kind of topologically nontrivial bulk-band crossing, giving rise to almost flat surface states. Yet, a direct evidence of the surface states is still lacking.

Excitement of solitons in the interaction of kinks of sine-Gordon equation with attracting impurity [PDF]
Компьютерные исследования и моделирование, 2012 We investigate analytically and numerically the structure and properties of localized two- and three-kink solutions of the sine-Gordon equation, which are excited in the region of the attracting impurity.

Interaction of moving breathers with an impurity [PDF]
, 2003 We analyze the influence of an impurity in the evolution of moving discrete breathers in a Klein--Gordon chain with non-weak nonlinearity. Three different behaviours can be observed when moving breathers interact with the impurity: they pass through the ...

Scalar potential effect in an integrable Kondo model [PDF]
, 1998 To study the impurity potential effect to the Kondo problem in a Luttinger liquid, we propose an integrable model of two interacting half-chains coupled with a single magnetic impurity ferromagnetically.
