Complex measure, coherent state and squeezed state representation

, 1998
Coherent states are studied within the framework of complex measurable processes. It is shown that squeezed states can be accommodated within this framework and all the relevant results relating to squeezed states are derived. A generalization to complex

Mechanism and disaster control new technology of strong ground pressure manifestation in ultra‐large mining face

Deep Underground Science and Engineering, EarlyView.
In response to the problem of strong mining pressure manifestation along the goaf roadway in a thick coal seam mining area, this study uses a new type of combined blasting roof cutting technology to effectively control the manifestation and deformation of mining pressure along the goaf roadway.

Generalized squeezed states from generalized coherent states

, 1993
Both the coherent states and also the squeezed states of the harmonic oscillator have long been understood from the three classical points of view: the (1) displacement operator, (2) annihilation- (or ladder-) operator, and (3) minimum-uncertainty ...

Planck scale corrections to the harmonic oscillator, coherent, and squeezed states

, 2017
The generalized uncertainty principle (GUP) is a modification of Heisenberg's Principle predicted by several theories of quantum gravity. It consists of a modified commutator between the position and momentum.

Mechanism of “seesaw‐type” rock burst in coal seam mining beneath mountainous areas

Deep Underground Science and Engineering, EarlyView.
This study reveals the mechanism of “seesaw‐type” rock bursts during coal mining beneath mountainous areas. The advancing working face induces nonuniform fracturing of the overburden. The detached mountain mass then undergoes a seesaw‐type rotational movement around a shifting pivot, driving the primary fracture through a characteristic “open‐close ...

Analysis of lining force transmission coefficient and surrounding rock displacement in lined rock caverns for underground gas storage

Deep Underground Science and Engineering, EarlyView.
This study derives an explicit expression for the lining force transmission coefficient of underground gas storage lined rock caverns (LRCs) via the complex variable function method, considering the displacement release coefficient. Taking the 1‰ tensile strain of surrounding rock as the criterion to determine lining thickness, it systematically ...

Two-Mode Coherent and Squeezed Vacuum States

, 2011
Using the antinormally-ordered characteristic function, we have determined the Q function for a two-mode coherent state as well as a two-mode squeezed vacuum state.
