Linear time-invariant Systems01:23

Linear time-invariant Systems

1.1K
A system is linear if it displays the characteristics of homogeneity and additivity, together termed the superposition property. This principle is fundamental in all linear systems. Linear time-invariant (LTI) systems include systems with linear elements and constant parameters.
The input-output behavior of an LTI system can be fully defined by its response to an impulsive excitation at its input. Once this impulse response is known, the system's reaction to any other input can be...

Time-Domain Interpretation of PD Control

438
Proportional-Derivative (PD) control is a widely used control method in various engineering systems to enhance stability and performance. In a system with only proportional control, common issues include high maximum overshoot and oscillation, observed in both the error signal and its rate of change. This behavior can be divided into three distinct phases: initial overshoot, subsequent undershoot, and gradual stabilization.
Consider the example of control of motor torque. Initially, a positive...

BIBO stability of continuous and discrete -time systems01:24

BIBO stability of continuous and discrete -time systems

1.1K
System stability is a fundamental concept in signal processing, often assessed using convolution. For a system to be considered bounded-input bounded-output (BIBO) stable, any bounded input signal must produce a bounded output signal. A bounded input signal is one where the modulus does not exceed a certain constant at any point in time.
To determine the BIBO stability, the convolution integral is utilized when a bounded continuous-time input is applied to a Linear Time-Invariant (LTI) system....

Transient and Steady-state Response01:24

Transient and Steady-state Response

655
In control systems, test signals are essential for evaluating performance under various conditions. The ramp function is effective for systems undergoing gradual changes, while the step function is suitable for assessing systems facing sudden disturbances. For systems subjected to shock inputs, the impulse function is the most appropriate test signal.
These test signals are integral in designing control systems to exhibit two key performance aspects: transient response and steady-state...

Time and frequency -Domain Interpretation of Phase-lag Control01:21

Time and frequency -Domain Interpretation of Phase-lag Control

441
Phase-lag controllers are widely used in control systems to improve stability and reduce steady-state errors. A dimmer switch controlling the brightness of a light bulb serves as a practical example of phase-lag control, gradually adjusting the bulb's brightness. Mathematically, phase-lag control or low-pass filtering is represented when the factor 'a' is less than 1.
Phase-lag controllers do not place a pole at zero, but instead influence the steady-state error by amplifying any...

Woodward–Hoffmann Selection Rules and Microscopic Reversibility01:34

Woodward–Hoffmann Selection Rules and Microscopic Reversibility

4.2K
Electrocyclic reactions, cycloadditions, and sigmatropic rearrangements are concerted pericyclic reactions that proceed via a cyclic transition state. These reactions are stereospecific and regioselective. The stereochemistry of the products depends on the symmetry characteristics of the interacting orbitals and the reaction conditions. Accordingly, pericyclic reactions are classified as either symmetry-allowed or symmetry-forbidden. Woodward and Hoffmann presented the selection criteria for...

This summary is machine-generated.

Researchers quantified temporal steering, a quantum correlation analogous to spatial Einstein-Podolsky-Rosen (EPR) steering. This new temporal steerable weight measure also quantifies non-Markovianity.

Area of Science:

  • Quantum Information Science
  • Quantum Foundations
  • Quantum Correlations

Background:

  • Einstein-Podolsky-Rosen (EPR) steering describes a unique quantum correlation enabling remote state preparation of a distant quantum system.
  • While typically viewed as spatial, a temporal analogue of EPR steering exists for single quantum systems.
  • A precise method for quantifying this temporal steering has been previously unavailable.

Purpose of the Study:

  • To introduce a precise quantification for single-system temporal steering.
  • To establish a direct analogy between temporal steering and the established EPR steerable weight.
  • To explore the properties and applications of this new temporal steering measure.

Main Methods:

  • Developed a measurement framework for temporal steering using semidefinite programming.
  • Introduced the concept of a 'temporal steerable weight' analogous to the EPR steerable weight.
  • Investigated the behavior of the temporal steerable weight under quantum dynamical maps.

Main Results:

  • Successfully quantified single-system temporal steering using the temporal steerable weight.
  • Demonstrated that the temporal steerable weight is a nonincreasing function under completely positive trace-preserving maps.
  • Established the temporal steerable weight as a sufficient and practical measure for strong non-Markovianity.

Conclusions:

  • The temporal steerable weight provides a robust tool for quantifying temporal steering.
  • This measure offers a new perspective on quantum correlations in the temporal domain.
  • The temporal steerable weight serves as a valuable indicator of non-Markovian dynamics in quantum systems.
