Phase transitions of antiferromagnetic Ising spins on the zigzag surface of an asymmetrical Husimi lattice
Ran Huang, Purushottam D. Gujrati
An asymmetrical 2D Ising model with a zigzag surface, created by diagonally cutting a regular square lattice, has been developed to investigate the thermodynamics and phase transit…
Correcting the Mistaken Identification of Nonequilibrium Microscopic Work
P. D. Gujrati
The energy change dE_k for the kth microstate is erroneously equated with the external work done on the microstate. It ignores the ubiquitous internal energy change d_iW_k due to f…
Hierarchy of Relaxation times and Residual Entropy: A Nonequilibrium Approach
P. D. Gujrati
We consider nonequilibrium (NEQ) states such as supercooled liquids and glasses that are described with use of internal variables. We classify the latter by state-dependent hierarc…
The Role of the Communal Entropy and Free Volume for the Viscosity Divergence near the Glass Transition: A New Conceptual Approach
P. D. Gujrati
The conventional approach to study glasses either requires considering the rapid drop in the excess entropy ΔS_ex or the free volume V_f. As the two quantities are not directly rel…
Jarzynski Equality and its Special Trajectory Ensemble Average Demystified
P. D. Gujrati
The special trajectory ensemble average (TEA), denoted by a subscript 0, in the Jarzynski Equality (JE) results in the Jensen inequality <R>_0 GT-EQ delta(F) for the work R done on…
