چکیده
The Casimir effect is a quantum phenomenon induced by the zero-point energy of relativistic fields confined in finite-size system. This for photon has been studied long time, while realization counterparts fermion Dirac/Weyl semimetals an open question. We theoretically demonstrate typical properties electron and show results from effective Hamiltonian realistic materials such as Cd$_3$As$_2$ Na$_3$Bi. find oscillation function thickness thin film, which stems existence nodes momentum space. Experimentally, can be observed films semimetals, where dependence thermodynamic quantities affected energy.

The Oscillating Dark Energy and Cosmological Casimir Effect
The role of dynamical cosmological Casimir effect to phantom (constant w ) and oscillating universe is discussed. It is shown explicitly that its role is not essential near to Big Rip singularity. However, the account of Casimir fluid makes the scale factor approach to Rip time to be faster. Rip time itself maybe changed too.

It is well known that nothing comes from nothing. In physics, however, this is not always the case. Surprisingly indeed, two electrically neutral conducting metallic plates placed in vacuum about half a micrometer apart attract each other, even at zero temperature, due to a force which was theoretically predicted in 1948 by the Dutch physicist Hendrik Casimir [1]. This force originates from the...
متن کاملHe and Casimir Effect
The friction force on the moving interface between two different vacuum states of superfluid 3He is considered at low temperature. Since the dominating mechanism of the friction is the Andreev reflection of the massless " relativistic " fermions, which live on the A-phase side of the interface, the results are similar to that for the perfectly reflecting mirror moving in the quantum vacuum.
