Quantum cloakings hide electronic devices

Abstract

As the modern development of electronic device smaller and smaller, quantum effect would become significant. Thus extending the concept of quantum mechanics into design of new electronic devices becomes more important. Controlling the movement of these electrons plays the central role in this issue. In this work, we propose a new quantum cloaking mechanism which has completely different to the previous work of Liao et al [1]. This mechanism is based on the scattering cancellation and the interplay among the nodal points of partial waves, that one can simultaneously guide the probability flux outside the interior and keep the total scattering cross section negligible. Moreover, we can put any electric devices inside quantum cloaking without affecting outside probability of matter wave. With the analogy between quantum matter waves and classical waves, the concept of our method can be applied in other fields, such as electromagnetic and acoustic systems, etc.

Approximate Quantum Cloaking and Almost-Trapped States

Allan Greenleaf, Yaroslav Kurylev, Matti J. Lassas +1 more

We describe potentials which act as approximate cloaks for matter waves. These potentials are derived from ideal cloaks for the conductivity and Helmholtz equations. At most energies E, if a potential is surrounded by an approximate cloak, then it becomes almost undetectable and unaltered by matter waves originating externally to the cloak. For certain E, however, the approximate cloaks are resonant, supporting wave functions almost trapped inside the cloaked region and negligible outside. Applications include dc or magnetically tunable ion traps and beam switches.

Perfect quantum cloaking of tilted cylindrical nanocavities

Constantinos A. Valagiannopoulos

A cornerstone in the operation of numerous detecting and sensing quantum setups is the sharp change in the response once a condition ceases to be effective; this regime is typically realized by perfectly cloaking a nanoinclusion from the propagating matter waves. Such a purpose is found well-served by optimally sized nanocylinders, embedded into a suitable quantum texture, that efficiently hide themselves from obliquely impinging electron beams. The optimal designs exhibit high selectivity for particle energies while being wideband with respect to incidence angles; these features render them deployable in various quantum devices from furtive sensors and detectors to quantum switches and matter-wave filters.

Cloaking of matter waves under the global Aharonov-Bohm effect

De‐Hone Lin, Pi‐Gang Luan

We discuss the Aharonov-Bohm effect of a magnetic flux for its influence on a two-dimensional quantum cloak. It is shown that the matter wave of a charged particle under the global influence of the Aharonov-Bohm effect can still be perfectly cloaked and guided by the quantum cloak. Since the presence of the global influence of a magnetic flux on charged particles is universal, the perfect cloaking and guiding nature not only provides an ideal setup to cloak an object from matter waves but also provides an ideal setup to test the global physics of charged matter waves in the presence of a bare magnetic flux.

Cloaking of Matter Waves

Shuang Zhang, Dentcho A. Genov, Cheng Sun +1 more

Invariant transformation for quantum mechanical systems is proposed. A cloaking of matter wave can be realized at given energy by designing the potential and effective mass of the matter waves in the cloaking region. The general conditions required for such a cloaking are determined and confirmed by both the wave and particle (classical) approaches. We show that it may be possible to construct such a cloaking system for cold atoms using optical lattices.

Furtive quantum sensing using matter-wave cloaks

Romain Fleury, Andrea Alù

We introduce the concept of furtive quantum sensing, demonstrating the possibility of concealing quantum objects from matter waves while maintaining their ability to interact and to get excited by the impinging particles. This is obtained by cloaking, with tailored homogeneous metamaterial layers, quantum systems having internal degrees of freedom. The effect is a low-observable quantum sensor with drastically reduced elastic scattering and optimized absorption levels, a concept that opens interesting venues in particle detection, high-efficiency electrical pumping, and quantum information processing.

Detecting the existence of an invisibility cloak using temporal steering

Shin-Liang Chen, Ching-Shiang Chao, Yueh-Nan Chen

An invisibility cloak provides a way to hide an object under the detection of waves. A good cloak guides the incident waves through the cloaking shell with few distortion. Even if one day a nearly perfect cloak is built, some important quantum effects, such as dephasing of the electron spin or photon polarization, may still remain. In this work, we consider the possibility that using the temporal steering of these degrees of freedom to detect the existence of an invisibility cloak.
