Variance of the Casimir force in an ideal Bose gas
Marek Napiórkowski, Marcin Pruszczyk
We consider an ideal Bose gas enclosed in a -dimensional slab of thickness . Using the grand canonical ensemble we calculate the variance of the thermal Casimir force acting…
Non-universal Casimir forces at Bose-Einstein condensation of an ideal gas: effect of Dirichlet boundary conditions
M. Napiorkowski, J. Piasecki, J. W. Turner
We analyze the Casimir forces for an ideal Bose gas enclosed between two infinite parallel walls separated by the distance D. The walls are characterized by the Dirichlet boundary…
Lateral critical Casimir force in two-dimensional inhomogeneous Ising strip. Exact results
Piotr Nowakowski, Marek Napiórkowski
We consider two-dimensional Ising strip bounded by two planar, inhomogeneous walls. The inhomogeneity of each wall is modeled by a magnetic field acting on surface spins. It is equ…
Repulsive Casimir forces at quantum criticality
P. Jakubczyk, M. Napiórkowski, T. Sęk
We study the Casimir effect in the vicinity of a quantum critical point. As a prototypical system we analyze the -dimensional imperfect (mean-field) Bose gas enclosed in a slab…
Lateral critical Casimir force in 2D Ising strip with inhomogeneous walls
Piotr Nowakowski, Marek Napiórkowski
We analyze the lateral critical Casimir force acting between two planar, chemically inhomogeneous walls confining an infinite 2D Ising strip of width . The inhomogeneity of each…
Quantum criticality of the imperfect Bose gas in d dimensions
P. Jakubczyk, M. Napiórkowski
We study the low-temperature limit of the d-dimensional imperfect Bose gas. Relying on an exact analysis of the microscopic model, we establish the existence of a second-order quan…
