In this paper, we study the relativistic quantum dynamics of spin- 12 particles interact with electromagnetic potentials in three-dimensional space–time. We solve the Dirac oscillator including the Aharonov–Bohm potential in (1+2)-dimensional rotational symmetry Gürses metric (Gürses, 1994), and analyze the Aharonov–Bohm effect on the energy eigenv...

In this work, the goal is to reach the thermodynamics properties produced by a family of the integrable Hamiltonians of the unitary groups of rank one in the Cayley-Klein space. In fact, this makes it possible through the general commutator relations between their generators of the desired Cayley-Klein group under investigation. On the other hand, ...

We generalize $1+1$-dimensional formalism derived by Ahmadi et. al. [Phys. Rev. D \textbf{93}, 124031] to investigate an effect of relativistic acceleration on localized two-mode Gaussian quantum states in $3+1$-dimensional spacetime. The following framework is then used to analyze entanglement of the Minkowski vacuum as witnessed by two accelerati...

AlPt is shown to be a chiral topological material with four-fold and six-fold degeneracies in the band structure. Fermi arc edge states span the whole Brillouin zone and their dispersion enables identification of the handedness of the chiral material.

The elastic energy resolution, integrated intensity, and peak intensity of the direct-geometry neutron chopper spectrometer 4SEASONS at Japan Proton Accelerator Research Complex (J-PARC) were re-investigated. This was done with respect to the incident energy and the rotation speed of the Fermi chopper using incoherent scattering of vanadium and sim...

Quantum entanglement is a form of correlation between quantum particles that has now become a crucial part in quantum information and communication science. For example, it has been shown to enable or enhance quantum processing tasks such as quantum cryptography, quantum teleportation, and quantum computing. However, quantum entanglement is prone t...

Here we consider an integral equation describing a fixed number of scalar particles which interact not through boson exchange but directly along light cones, similarly as in bound state equations such as the Bethe-Salpeter equation. The equation involves a multi-time wave function $\psi(x_1,...,x_N)$ with $x_i=(t_i,\mathbf{x}_i) \in \mathbb{R}^4$ a...

In this paper we consider a new geometric approach to Madelung's quantum hydrodynamics (QHD) based on the theory of a gauge connection. Unlike previous similar approaches this connection is no longer an exact differential, instead allowing for a constant curvature and endowing QHD with intrinsic non-zero holonomy through the use of only single-valu...

The uncertainty principle lies at the heart of quantum physics, and is widely thought to be a fundamental limit on the measurement precisions of incompatible observables. Here we show that this mode of thought only pertains to the lowest order approximation of a generalized uncertainty principle, where the incompatibility between observables is int...

We study four-dimensional Chern-Simons theory on D x \C (where D is a disk), which is understood to describe rational solutions of the Yang-Baxter equation from the work of Costello, Witten and Yamazaki. We find that the theory is dual to a boundary theory, that is a three-dimensional analogue of the two-dimensional chiral WZW model. This boundary ...
