Casimir and Helmholtz forces in one-dimensional Ising model with Dirichlet (free) boundary conditions
D. M. Dantchev, N. S. Tonchev, J. Rudnick
Attention in the literature has increasingly turned to the issue of the dependence on ensemble and boundary conditions of fluctuation-induced forces. We have recently investigated…
Casimir versus Helmholtz forces: Exact results
D. M. Dantchev, N. S. Tonchev, J. Rudnick
Recently, attention has turned to the issue of the ensemble dependence of fluctuation induced forces. As a noteworthy example, in systems the statistical mechanics underlyin…
Membrane Stretching Elasticity of Lipid Vesicle and Thermal Shape Fluctuations
Isak Bivas, Nicholay S. Tonchev
One of the most widely used methods for determination of the bending elasticity modulus of model lipid membranes is the analysis of the shape fluctuations of nearly spherical lipid…
Monotone Riemannian metrics and dynamic structure factor in condensed matter physics
N. S. Tonchev
An analytical approach is developed to the problem of computation of monotone Riemannian metrics (e.g. Bogoliubov-Kubo-Mori, Bures, Chernoff, etc.) on the set of quantum states. Th…
On the statistical mechanics of shape fluctuations of nearly spherical lipid vesicle
I. Bivas, N. S. Tonchev
The mechanical properties of biological membranes play an important role in the structure and the functioning of living organisms. One of the most widely used methods for determina…
Mixed-state fidelity susceptibility through iterated commutator series expansion
N. S. Tonchev
We present a perturbative approach to the problem of computation of mixed-state fidelity susceptibility (MFS) for thermal states. The mathematical techniques used provides an analy…
