Random free-fermion quantum spin chain with multi-spin interactions
Francisco C. Alcaraz, José A. Hoyos, Rodrigo A. Pimenta
We study the effects of quenched disorder in a class of quantum chains with (p+1)-multispin interactions exhibiting a free fermionic spectrum, paying special attention to the case…
Ising analogues of quantum spin chains with multispin interactions
Francisco C. Alcaraz, Rodrigo A. Pimenta, Jesko Sirker
A new family of free fermionic quantum spin chains with multispin interactions was recently introduced. Here we show that it is possible to build standard quantum Ising chains -- b…
Free-parafermionic and free-fermionic quantum chains
Francisco C. Alcaraz, Rodrigo A. Pimenta
The relationship between the eigenspectrum of Ising and XY quantum chains is well known. Although the Ising model has a symmetry and the XY model a symmetry, both mod…
Integrable quantum spin chains with free fermionic and parafermionic spectrum
Francisco C. Alcaraz, Rodrigo A. Pimenta
We present a general study of the large family of exact integrable quantum chains with multispin interactions introduced recently in \cite{AP2020}. The exact integrability follows…
Free fermionic and parafermionic quantum spin chains with multispin interactions
Francisco C. Alcaraz, Rodrigo A. Pimenta
We introduce a new a family of multispins quantum chains with a free-fermionic () or free-parafermionic () eigenspectrum. The models have interacting spins…
Critical phases in the raise and peel model
D. A. C. Jara, F. C. Alcaraz
The raise and peel model (RPM) is a nonlocal stochastic model describing the space and time fluctuations of an evolving one dimensional interface. Its relevant parameter is the…
