Magnetic properties of the frustrated decorated Ising chain
D. V. Laptiev, O. O. Krivchikov, Yu. V. Savin +1
Using the Kramers-Wannier transfer matrix method we studied several decorated Ising chains. The exact expressions for thermodynamic characteristics, including the ground state char…
Giant caloric effects in spin chain materials
A. A. Zvyagin, V. V. Slavin
The giant electro- and elasto-caloric effects in spin chain materials are predicted. The theory is based on the exact quantum mechanical solution of the problem. It is shown that t…
Entanglement Entropy of Free Fermions with a Random Matrix as a One-Body Hamiltonian
L. Pastur, V. Slavin
We consider a quantum system of large size and its subsystem of size assuming that is much larger than , which can also be sufficiently large, i.e., $1 \ll L \lesssi…
On the Area Law for Disordered Free Fermions
L. Pastur, V. Slavin
We study theoretically and numerically the entanglement entropy of the -dimensional free fermions whose one body Hamiltonian is the Anderson model. Using basic facts of the expo…
