Analogs of fundamental physical phenomena can be used in two ways. One way consists in
reproducing specific aspects of the classical or quantum gravity of quantum fields in curved …

We analyze the Casimir effect for a flavor doublet of mixed scalar fields confined inside a
one-dimensional finite region. In the framework of the unitary inequivalence between mass …

Assuming that the degrees of freedom of a black hole are finite in number and of fermionic
nature, we naturally obtain, within a second-quantized toy model of the evaporation, that the …

We present a detailed study of the Bardeen-Cooper-Schrieffer (BCS) gap equation
“replicae” or excited vacuum states, orthogonal to the ground-state one, in the chiral-quark …

After a short introduction to the generalized uncertainty principle (GUP), we discuss heuristic
derivations of the Casimir effect, first from the usual Heisenberg uncertainty principle (HUP) …

We discuss the representations of the algebra of quantization, the canonical commutation
relations, in a scalar quantum field theory with spontaneously broken U (1) internal …

In this study, we develop quantum measurement theory for quantum systems described by
C∗-algebras. This is the first step to establish measurement theory for interacting quantum …

When one tries to take into account the nontrivial vacuum structure of quantum field theory,
the standard functional-integral tools, such as generating functionals or transitional …

Using a hyperbolic ring based formalism, it is shown that special unitary groups correspond
to thermo-algebras for closed quantum systems, while for open systems, the full unitary …

One of the major ways in which quantum mechanics differs from classical mechanics is the
existence of special quantum correlations-entanglement. Typical quantum states are highly …
