Squeezed states: A geometric framework [PDF]
, 1992 A general definition of squeezed states is proposed and its main features are illustrated through a discussion of the standard optical coherent states represented by 'Gaussian pure states'.

General two-mode squeezed states [PDF]
, 1988 The states Θ|A1A2〉 are considered, where the operators Θ are associated with a unitary representation of the group Sp(4,ℝ), and the two-mode Glauber coherent states |A1A2> are joint eigenstates of the destruction operators a1 and a2 for the two ...

Squeezed Coherent States in Double Optical Resonance
Photonics, 2021 In this work, we consider a “Λ-type” three-level system where the first transition is driven by a radiation field initially prepared in a squeezed coherent state, while the second one by a weak probe field. If the squeezed field is sufficiently strong to

Ultrawide Bandwidth Optomechanical Magnetometry Using Flux Concentration
Advanced Functional Materials, EarlyView.High‐permeability flux concentrators enable ultrawide‐bandwidth chip‐scale optomechanical magnetometry by exploiting magnetic nonlinearity to up‐convert low‐frequency fields to the mechanical resonance, where sensitivity is optimal. This enables flat wideband operation over more than four orders of magnitude, from tens of kilohertz to sub‐hertz ...

What are squeezed states really like [PDF]
, 1984 The simple harmonic oscillator and some quantum mechanics are reviewed. Then a special case of the squeezed states, the coherent states, is discussed. Next, the coherent states are described from the operator formalism.

Quantum-enhanced multiparameter estimation and compressed sensing of a field
SciPost Physics, 2023 We show that a significant quantum gain corresponding to squeezed or over-squeezed spin states can be obtained in multiparameter estimation by measuring the Hadamard coefficients of a 1D or 2D signal.

Pullback Coherent States, Squeezed States and Quantization
Symmetry, Integrability and Geometry: Methods and Applications, 2022 In this semi-expository paper, we define certain Rawnsley-type coherent and squeezed states on an integral Kähler manifold (after possibly removing a set of measure zero) and show that they satisfy some properties which are akin to maximal likelihood property, reproducing kernel property, generalised resolution of identity property and overcompleteness.

Advanced Materials, EarlyView.The new Cu‐containing MOF (Me2NH2)(CuICl2)@[Cu4(INA)4Cl2O]·1.5dmf (3) contains a cation and an anion as guests and shows UV‐near‐mid‐IR absorption and near‐IR emission. MOF 3 shows gas‐solid reactivity in the presence of NH3 and HCOOH to yield two new 3D MOF.

Production of squeezed states for macroscopic mechanical oscillator [PDF]
, 1994 The possibility of squeezed states generation for macroscopic mechanical oscillator is discussed. It is shown that one can obtain mechanical oscillator in squeezed state via coupling it to electromagnetic oscillator (Fabry-Perot resonator) and pumping ...
