Summary
We discovered a novel dynamical phase transition in spin models, moving between collective and scalable squeezing phases. This finding has potential applications in quantum sensing and simulation.
Area of Science:
- Quantum physics
- Condensed matter physics
- Non-equilibrium dynamics
Background:
- Spin-1/2 bilayer XXZ models exhibit power-law interactions.
- These models are known to generate entanglement via two-mode squeezing.
Purpose of the Study:
- Investigate phase transitions in non-equilibrium dynamics.
- Characterize different squeezing phases and their scaling.
- Explore potential applications in quantum technologies.
Main Methods:
- Analysis of power-law interacting spin-1/2 bilayer XXZ models.
- Identification of dynamical phases based on squeezing characteristics.
- Study of universal scaling laws and divergent timescales.
Main Results:
- A transition between a collective phase (Heisenberg-limited squeezing) and a partially collective phase (scalable squeezing) was identified.
- Universal scaling of squeezing dynamics was found in terms of system parameters.
- A divergent timescale was observed, distinguishing the dynamical phases.
Conclusions:
- The study establishes distinct dynamical phases within non-equilibrium critical phenomena.
- The identified phase transition offers potential for quantum sensing and quantum simulation.
- Findings are relevant for cold-atomic, molecular, or Rydberg platforms.

In designing and analyzing filters, resonant circuits, or circuit analysis at large, working with standard element values like 1 ohm, 1 henry, or 1 farad can be convenient before scaling these values to more realistic figures. This approach is widely utilized by not employing realistic element values in numerous examples and problems; it simplifies mastering circuit analysis through convenient component values. The complexity of calculations is thereby reduced, with the understanding that...

01:30The Squeeze Theorem
219
Certain mathematical functions exhibit unpredictable or highly variable behavior near specific input values, making direct evaluation of their limits challenging. This complexity may arise from rapid oscillations or irregular patterns that obscure the function’s trend. In such cases, the Squeeze Theorem offers a reliable method for determining limits.According to the Squeeze Theorem, if a function is confined between two other functions near a particular point, and both outer functions...

02:33Phase Transitions: Sublimation and Deposition
19.5K
Some solids can transition directly into the gaseous state, bypassing the liquid state, via a process known as sublimation. At room temperature and standard pressure, a piece of dry ice (solid CO2) sublimes, appearing to gradually disappear without ever forming any liquid. Snow and ice sublimate at temperatures below the melting point of water, a slow process that may be accelerated by winds and the reduced atmospheric pressures at high altitudes. When solid iodine is warmed, the solid sublimes...

02:39Phase Transitions: Melting and Freezing
14.5K
Heating a crystalline solid increases the average energy of its atoms, molecules, or ions, and the solid gets hotter. At some point, the added energy becomes large enough to partially overcome the forces holding the molecules or ions of the solid in their fixed positions, and the solid begins the process of transitioning to the liquid state or melting. At this point, the temperature of the solid stops rising, despite the continual input of heat, and it remains constant until all of the solid is...
