The Casimir effect arises from the zero-point energy of particles in momentum space
deformed by the existence of two parallel plates. For degrees of freedom on the lattice, its …

In this paper, we extend previous results on the quantum vacuum or Casimir energy, for a
noninteracting rotating system and for an interacting nonrotating system, to the case where …

In this work we consider a fermionic chain of finite length ℓ. Fermions are allowed to interact
and are forced to obey boundary conditions, thus altering the process of condensation. Our …

With the intent of exploring how the interplay between boundary effects and chiral symmetry
breaking may alter the thermodynamical behavior of a system of strongly interacting …

Motivated by evidence for quark-gluon plasma signatures in small systems, we study a
simple model of a massless, noninteracting scalar field confined with Dirichlet boundary …

Finite-volume effects for the nucleon chiral partners are studied within the framework of the
parity-doublet model. Our model includes the vacuum energy shift for nucleons, which is the …

The vacuum expectation value (VEV) of the fermionic current density is investigated in the
geometry of two parallel branes in locally AdS spacetime with a part of spatial dimensions …

We propose a definition of the Casimir energy for free lattice fermions. From this definition,
we study the Casimir effects for the massless or massive naive fermion, Wilson fermion, and …

In this work we examine a system consisting of a confined one-dimensional arrangement of
atoms that we describe by using the 2-dimensional CPN-1 model, restricted to an interval …

The Casimir effect is a quantum phenomenon rooted in the fact that vacuum fluctuations of
quantum fields are affected by the presence of physical objects and boundaries. Since the …
