Magneto- and electrocaloric effects in superconducting nanowire with Majorana zero
modes and electron correlations
The peculiarities of thermodynamic behaviour of an open superconducting nanowire with the strong Rashba spinorbit interaction and external magnetic field are considered both for the topological and for the topologically trivial phases. The main attention is paid to the magnetocaloric and electrocaloric effects that manifest themselves in changing the temperature of the system under adiabatic changes in external magnetic and electric fields. It is demonstrated the correspondence between the realization of the topological phase with Majorana edge states and the series of caloric anomalies. With the use of density matrix renormalization group method it is demonstrated that the established features of the open nanowires are preserved even when a strong electron correlations are taken into account. The question of possible manifestations of the caloric anomalies in the quantum computations with Majorana modes is discussed.
