This paper discusses recent developments on quantum electrodynamical (QED) phenomena, such as the Casimir effect, and their use in nanomechanics and nanotechnology in general. Casimir forces and torques arise from quantum fluctuations of vacuum or, more generally, from the zero-point energy of materials and their dependence on the boundary conditions of the electromagnetic fields. Because the latter can be tailored, this raises the interesting possibility of designing QED forces for specific… 
Recent progress in engineering the Casimir effect – applications to nanophotonics, nanomechanics, and chemistry
Abstract Quantum optics combines classical electrodynamics with quantum mechanics to describe how light interacts with material on the nanoscale, and many of the tricks and techniques used in
The Casimir effect in microstructured geometries
In 1948, Hendrik Casimir predicted that a generalized version of van der Waals forces would arise between two metal plates due to quantum fluctuations of the electromagnetic field. These forces
The Casimir force and micro-electromechanical systems at submicron-scale separations
Quantum mechanics teaches us that vacuum is not empty. Rather, it contains all kinds of virtual particles. The energy of such particles is called zero point energy. If two surfaces come in close
The Casimir force control in nano and micro electromechanical systems
In this thesis we deal with the analysis and measurement of dispersive surface forces, specifically the Casimir force. Applying Lifshitz theory makes it possible to take into account the material
Electrodynamic Force, Casimir Effect, and Stiction Mitigation in Silicon Carbide Nanoelectromechanical Switches.
TLDR
Finite element modeling and analytical calculations demonstrate that EDF becomes dominant over elastic restoring force in such SiC NEMS when the switching gap shrinks to a few nanometers, leading to irreversible stiction at contact.
Nonlinear Actuation of Casimir Oscillators toward Chaos: Comparison of Topological Insulators and Metals
In the current study, we explore the sensitivity of the actuation dynamics of electromechanical systems on novel materials, e.g., Bi2Se3, which is a well-known 3D Topological Insulator (TI), and

The Casimir force between real materials: Experiment and theory
The physical origin of the Casimir force is connected with the existence of zero-point and thermal fluctuations. The Casimir effect is very general and finds applications in various fields of
Sensitivity of Casimir oscillators on geometry and optical properties
The dependence of the Casimir force on the optical properties and geometry of interacting materials makes possible to tailor the actuation dynamics of micro/nano actuators. In this research, we study
Applications of Casimir forces: Nanoscale actuation and adhesion
Here, we discuss possible applications of the Casimir forces in micro- and nanosystems. The main part of this paper is devoted to actuation with quantum fluctuations and to the relative contribution

Quantum Mechanical Actuation of Microelectromechanical Systems by the Casimir Force
TLDR
This work demonstrates the Casimir effect in microelectromechanical systems using a micromachined torsional device and shows that quantum electrodynamical effects play a significant role when the separation between components is in the nanometer range.
Quantum electrodynamical torques in the presence of Brownian motion
Quantum fluctuations of the electromagnetic field give rise to a zero-point energy that persists even in the absence of electromagnetic sources. One striking consequence of the zero-point energy is

The static Casimir effect describes an attractive force between two conducting plates, due to quantum fluctuations of the electromagnetic (EM) field in the intervening space. Thermal fluctuations of
The role of the casimir effect in the static deflection and stiction of membrane strips in microelectromechanical systems (MEMS)
We present an analysis describing how the Casimir effect can deflect a thin microfabricated rectangular membrane strip and possibly collapse it into a flat, parallel, fixed surface nearby. In the
Path-integral approach to the dynamic Casimir effect with fluctuating boundaries
A path-integral formulation is developed for the dynamic Casimir effect. It allows us to study small deformations in space and time of the perfectly reflecting (conducting) boundaries of a cavity.
Cooling a nanomechanical resonator with quantum back-action
TLDR
The back-action of a superconducting single-electron transistor (SSET) on a radio-frequency nanomechanical resonator is measured to anticipate the use of these back- action effects to prepare ultracold and quantum states of mechanical structures, which would not be accessible with existing technology.

Zero-point fluctuations in quantum fields give rise to observable forces between material bodies, the so-called Casimir forces. In these lectures I present the theory of the Casimir effect, primarily

The Casimir effect is analyzed. This effect consists of a polarization of the vacuum of quantized fields which arises as a result of a change in the spectrum of vacuum oscillations when the
