Boron doping in gallium oxide from first principles

期刊: JOURNAL OF PHYSICS COMMUNICATIONS, 2020; 4 (12)

We study the feasibility of boron doping in gallium oxide (Ga2O3) for neutron detection. Ga2O3 is a wide band gap, radiation-hard material with potent......

New results by low momentum approximation from relativistic quantum mechanics equations and suggestion of experiments

期刊: JOURNAL OF PHYSICS COMMUNICATIONS, 2020; 4 (12)

A fundamental belief is that the formulism of relativistic quantum mechanics equations (RQMEs) should remain in low momentum motion. However, it is fo......

Direct measurement methods of density matrix of an entangled quantum state

期刊: JOURNAL OF PHYSICS COMMUNICATIONS, 2020; 4 (7)

In general, the state of a quantum system represented by the density operator and its determination is a fundamental problem in quantum theory. In thi......

Solving Klein's paradox

期刊: JOURNAL OF PHYSICS COMMUNICATIONS, 2020; 4 (12)

We figure out the famous Klein's paradox arising from the reflection problem when a Dirac particle encounters a step potential with infinite width. Th......

The Thomas theorem and the Efimov States within a generalized Bohr model

期刊: JOURNAL OF PHYSICS COMMUNICATIONS, 2020; 4 (8)

Using a generalized Bohr model and the hyper-spherical formalism for a three-body system, we derive the universal energy functions. We apply our model......

Eigenfrequency loci crossings, veerings and mode splittings of two cantilevers coupled by an overhang

期刊: JOURNAL OF PHYSICS COMMUNICATIONS, 2020; 4 (8)

Eigenfrequency loci veering, which indicates strong mode coupling and sometimes mode localization, is a much sought-after property in the applications......

Holder stability in determining elastic coefficients of Biot's system in poroelastic media

期刊: JOURNAL OF PHYSICS COMMUNICATIONS, 2020; 4 (8)

In this paper, we investigate an inverse problem of determining the four spatially varying elastic coefficients of Biot's system simultaneously, i.e.,......

Resolution of the Plane-symmetric Einstein-Maxwell fields with a generalization of the Lambert W function

期刊: JOURNAL OF PHYSICS COMMUNICATIONS, 2020; 4 (8)

Here, the Einstein-Maxwell field equation with plane-symmetry is resolved and a solution involving a generalized Lambert W function is obtained. This ......

Weak measurement of the optical polarization, chirality and orbital angular momentum via metasurface with polarization filtering

期刊: JOURNAL OF PHYSICS COMMUNICATIONS, 2020; 4 (9)

We propose a metasurface to evaluate the polarization, chirality and orbital angular momentum of the incident light. By employing the weak measurement......

Visualizing one-dimensional non-hermitian topological phases

期刊: JOURNAL OF PHYSICS COMMUNICATIONS, 2020; 4 (9)

We develop a graphic approach for characterizing one-dimensional non-Hermitian topological phases. The eigenstates of energy bands are mapped to a gra......

Susceptibility to disorder of the optimal resetting rate in the Larkin model of directed polymers

期刊: JOURNAL OF PHYSICS COMMUNICATIONS, 2020; 4 (9)

We consider the Larkin model of a directed polymer with Gaussian-distributed random forces, with the addition of a resetting process whereby the trans......

A semi-analytical model for the scale-dependent friction of nanosized asperity

期刊: JOURNAL OF PHYSICS COMMUNICATIONS, 2020; 4 (9)

The friction of a nanosized spherical asperity in commensurate contact with a flat substrate is investigated by performing molecular dynamics simulati......

The average value of the spin squared operator as an order parameter for spin phase transitions without spontaneous lowering of symmetry

期刊: JOURNAL OF PHYSICS COMMUNICATIONS, 2020; 4 (9)

Phase transitions from the low-spin to the high-spin state are a unique physical phenomenon without lowering of symmetry. In contrast to magnetic phas......

Quantitatively determining the degree of spin fluctuations in actinide metals and compounds

期刊: JOURNAL OF PHYSICS COMMUNICATIONS, 2020; 4 (10)

Actinide materials are well-documented for nuclear properties, but their 5f electrons that produce exotic phenomena are not, due to the complexity of ......

Plasmon modulation in three-dimensional periodic structure of graphene ribbons

期刊: JOURNAL OF PHYSICS COMMUNICATIONS, 2020; 4 (11)

In the article the spectra of plasmon-polariton in a three-dimensional periodic structure of graphene ribbons embedded in a medium were studied at the......
