Phase Transitions: Melting and Freezing

12.4K
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...

Third Law of Thermodynamics

18.9K
A pure, perfectly crystalline solid possessing no kinetic energy (that is, at a temperature of absolute zero, 0 K) may be described by a single microstate, as its purity, perfect crystallinity,and complete lack of motion means there is but one possible location for each identical atom or molecule comprising the crystal (W = 1). According to the Boltzmann equation, the entropy of this system is zero.

Stability of Equilibrium Configuration

449
Understanding the stability of equilibrium configurations is a fundamental part of mechanical engineering. In any system, there are three distinct types of equilibrium: stable, neutral, and unstable.
A stable equilibrium occurs when a system tends to return to its original position when given a small displacement, and the potential energy is at its minimum. An example of a stable equilibrium is when a cantilever beam is fixed at one end and a weight is attached to the other end. If the weight...

Stability

The time response of a linear time-invariant (LTI) system can be divided into transient and steady-state responses. The transient response represents the system's initial reaction to a change in input and diminishes to zero over time. In contrast, the steady-state response is the behavior that persists after the transient effects have faded.
The stability of an LTI system is determined by the roots of its characteristic equation, known as poles. A system is stable if it produces a bounded...

Temperature and Thermal Equilibrium

6.7K
Heat and temperature are essential concepts for everyone every day. The study of heat and temperature is part of an area of physics known as thermodynamics. It is not always easy to distinguish heat and temperature.
The concept of temperature has evolved from the common concepts of hot and cold. The scientific definition of temperature explains more than just our sense of hot and cold. Temperature is operationally defined as the quantity measured with a thermometer. Furthermore, temperature is...

Stability of Equilibrium Configuration: Problem Solving

609
The stability of equilibrium configurations is an important concept in physics, engineering, and other related fields. In simple terms, it refers to the tendency of an object or system to return to its equilibrium position after being disturbed. The stability of an equilibrium configuration can be analyzed by considering the potential energy function of the system and examining its behavior near the equilibrium point.
Problem-solving in the context of the stability of equilibrium configuration...

Area of Science:

  • Quantum physics
  • Condensed matter physics
  • Statistical mechanics

Background:

  • Discrete time crystals (DTCs) are novel phases of matter exhibiting periodic behavior in driven systems.
  • Existing DTCs often rely on prethermal or many-body localization, limiting their stability.
  • Understanding robust DTCs is crucial for quantum technologies.

Purpose of the Study:

  • To theoretically and numerically demonstrate the existence of finite-temperature discrete time crystals (DTCs) in open quantum systems.
  • To investigate the stability and properties of these novel DTCs against perturbations.
  • To establish a general framework for realizing DTCs using classical cellular automata.

Main Methods:

  • Mapping probabilistic cellular automata to open classical Floquet systems with Langevin dynamics.
  • Introducing a variant of the Toom cellular automaton (the "π-Toom time crystal").
  • Numerical simulations to evidence the DTC phase transition and analyze fluctuations.

Main Results:

  • Demonstrated finite-temperature discrete time crystals (DTCs) in a 2D Floquet Hamiltonian system.
  • The discovered DTCs possess infinite autocorrelation time and are stable to arbitrary perturbations.
  • Established a connection between cellular automata and open quantum Floquet systems for DTC realization.

Conclusions:

  • Finite-temperature DTCs with robust order can be realized in open quantum systems.
  • The mapping to cellular automata provides a powerful tool for discovering and understanding DTCs.
  • The findings suggest the existence of DTCs in all dimensions (d≥1).
