Influence of direct dipole-dipole interactions on the optical response of 2D materials in strongly inhomogeneous infrared cavity fields [PDF]
arXiv, 2023 A two-dimensional (2D) material, formed for example by a self-assembled molecular monolayer or by a single layer of a van der Walls material, can couple efficiently with photonic nanocavities, potentially reaching the strong coupling regime. The coupling can be modelled using classical harmonic oscillator models or cavity quantum electrodynamics ...

Abnormal field-dependence of magnetocaloric effect in ErB4 and TmB4
AIP Advances, 2020 The coupled system of multi-degrees of freedom, such as charge, spin, orbital and lattice, has recently received much attention due to its potential to improve the magnetocaloric effect (MCE).

Electrodynamics of Amorphous Media at Low Temperatures [PDF]
, 2005 Amorphous solids exhibit intrinsic, local structural transitions, that give rise to the well known quantum-mechanical two-level systems at low temperatures. We explain the microscopic origin of the electric dipole moment of these two-level systems: The dipole emerges as a result of polarization fluctuations between near degenerate local configurations,

Electroweak baryogenesis and electron EDM in the TNMSSM
European Physical Journal C: Particles and FieldsWe have studied the impact of CP-violating (CPV) effects on electroweak baryogenesis (EWBG) and the electric dipole moment (EDM) of electron ( $$d_e$$ d e ), the electric dipole moment (EDM) of mercury neutron ( $$d_n$$ d n ) and the electric dipole ...

Level Set Method for Quantum Control of Dipole Moment [PDF]
arXiv, 2004 We investigate the level set method (LSM) in a specific quantum context; namely the dipole transition moment for a system with a nontrivial Morse potential. We draw equal moment sets in the two-dimensional space of two important parameters of the potential, namely the depth of the potential and its width.

ALP-assisted strong first-order electroweak phase transition and baryogenesis
Journal of High Energy PhysicsAxion-like particles (ALPs) can be naturally lighter than the electroweak scale. We consider an ALP that couples to the Standard Model Higgs to achieve the strong first-order electroweak phase transition.

Interlevel absorption of electromagnetic waves by nanocrystal with divalent impurity
Condensed Matter Physics, 2014 The energy spectrum of central divalent impurity is calculated using the effective mass approximation in a spherical quantum dot (QD). The dipole moment and oscillator strength of interlevel transition is defined.

Inducing complete population oscillations in systems with externally induced dipole moments [PDF]
arXiv, 2004 A two level system is considered which has no static dipole moment, e.g. molecule $H_2$ in its ground electronic state. If strong enough external field is applied, it will dynamically distort such a system and supply it with time (and field) dependent dipole moment.
