Solar energetic particles (SEPs) and geomagnetic storms related to coronal mass ejections (CMEs) are a major research topic in solar-terrestrial and geospace physics. Solar energetic particles and coronal mass ejections ...

Quantum mechanics has both deepened our understanding of the physical reality and allowed development of quantum technologies beating their classical counterparts in efficiency, security, and sensitivity. As a major downside, ...

Accretion is one of the most important processes in astrophysics. Accretion discs are observed in a very large wavelength range, from infrared to X-rays, and in a very large range of scales: from several kilometers (accretion ...

Relativistic jets launched by a super-massive black holes are among the most extreme particle accelerators in the Universe. BL Lac objects host a relativistic jet that points very close to our line of sight. They are the ...

The problem of the dynamics in open and correlated quantum systems has gained attention in recent years due to the impressive experimental advances that were made in quantum transport in molecular systems. The importance ...

Quantum theory is a particularly important instance of an operational theory.By looking at quantum theory from the perspective of more abstract operational framework one is able to study its properties in a wider context. ...

Solar energetic particles (SEPs) are an important component of space weather. They pose a serious radiation hazard to electronic equipment and biological organisms in space. They are produced in explosive events such as ...

This thesis addresses the use of covariant phase space observables in quantum tomography. Necessary and sufficient conditions for the informational completeness of covariant phase space observables are proved, and some ...

This thesis is devoted to understanding and improving technologically important III-V compound semiconductor (e.g. GaAs, InAs, and InSb) surfaces and interfaces for devices. The surfaces and interfaces of crystalline ...
