The Jaynes–Cummings Model (JCM) has recently been receiving increased attention as
one of the simplest, yet intricately nonlinear, models of quantum physics. Emphasising the …

We find that a quantum device having an accessory involving precision measurement can
have an enhancement of its metrological precision in estimating an unknown parameter of …

We find that insertion of glassy disorder, accidental or engineered, can lead to enhancement
of metrological precision in estimating an unknown parameter of a quantum system. We …

Equilibrium quantum many-body systems in the vicinity of phase transitions generically
manifest universality. In contrast, limited knowledge has been gained on possible universal …

Disorder in one-dimensional (1D) many-body systems facilitates abundant phases such as
many-body localization (MBL) and thermalization. However, it remains unclear regarding …

first excited states - IOPscience This site uses cookies. By continuing to use this site you agree …

We formulate a protocol for a four-stroke quantum Otto engine that is capable of achieving
superior performance when operating between two thermal reservoirs: one at a positive spin …

Entanglement and quantum correlations between atoms are not usually considered key
ingredients of the superradiant phase transition. Here we consider the Tavis-Cummings …

The possibility of exploiting heterogeneous quantum systems to high precision, for storing,
processing, and transmitting information, makes them ideal candidates for multitasking …

Dynamics of atom–field correlations and single-mode nonclassicalities present in the
resonant Jaynes–Cummings model are investigated using negativity and entanglement …
