Enhancing Acceleration Radiation from Ground-State Atoms via Cavity Quantum Electrodynamics [PDF]
When ground state atoms are accelerated through a high Q microwave cavity, radiation is produced with an intensity which can exceed the intensity of Unruh acceleration radiation in free space by many orders of magnitude.

Dipotassium zinc tetraiodate(V) dihydrate
The title compound, K2Zn(IO3)4·2H2O, contains two symmetry-independent K and I atoms. These atoms, as well as the Zn atom, are coordinated by shared O atoms and, moreover, the Zn atom is coordinated by two water molecules in trans positions. The

It was proven that the class of stable interatomic potentials can be represented exactly as a superposition of Yukawa potentials. In this paper, an auxiliary scalar field was introduced to describe the dynamics of a system of neutral particles (atoms) in

Ground-State Spaces of Frustration-Free Hamiltonians
We study the ground-state space properties for frustration-free Hamiltonians. We introduce a concept of `reduced spaces' to characterize local structures of ground-state spaces. For a many-body system, we characterize mathematical structures for the set $

Vibrational modes and spectrum of oscillators on a scale-free network
We study vibrational modes and spectrum of a model system of atoms and springs on a scale-free network in order to understand the nature of excitations with many degrees of freedom on the scale-free network.

Effect of polarity and steric on the rate addition of free radicals to Alkenes [PDF]
In this investigation, the effective factors on the addition rate for hydroxy methyl and cynomethyl free radicals to some alkenes have been studied using quantum mechanics methods. Where in this study, physical properties like the electron density on the

Shadow-free multimers as extreme-performance meta-atoms
We generalize the concept of parity-time symmetric structures with the goal to create meta-atoms exhibiting extraordinary abilities to overcome the presumed limitations in the scattering of overall lossless particles, such as non-zero forward scattering ...

Confinement effects in a guided-wave interferometer with millimeter-scale arm separation
Guided-wave atom interferometers measure interference effects using atoms held in a confining potential. In one common implementation, the confinement is primarily two-dimensional, and the atoms move along the nearly free dimension under the influence of

Optimal building block of multipartite quantum battery in the driven-dissipative charging
To take quantum advantage of collective effects in many-body system, we design an elementary block for building a quantum battery with the optimal number of atoms in a common thermal bath, which is charged collectively by a harmonic driving.
