چکیده
Thermodynamics of quantum systems and thermal machines are rapidly developing fields, which have already delivered several promising results, as well raised many intriguing questions. Many-body present new opportunities stemming from many-body effects. At the same time, they pose challenges related to physics. In this short review we discuss some recent developments on technologies based systems. We mainly focus effects in machines. also briefly address role played by development batteries probes.

Quantum Many Body System at Integer Coupling
The 1/r2 quantum many body problem, and the closely related Haldane-Shastry 1/r2 Heisenberg chain, are the subject of intense theoretical study at present, due in part to their relationship to an ideal gas obeying fractional statistics (see [1] for a review). One direction of study has been the exact calculation of some ground state correlation functions [1-5]. Let us briefly summarize the main...
متن کاملQuantum Many–Body Problems and Perturbation Theory
We show that the existence of algebraic forms of exactly-solvable A−B− C−D and G2, F4 Olshanetsky-Perelomov Hamiltonians allow to develop the algebraic perturbation theory, where corrections are computed by pure algebraic means. A classification of perturbations leading to such a perturbation theory based on representation theory of Lie algebras is given. In particular, this scheme admits an ex...
متن کاملQuantum Computation, Complexity, and Many-body Physics
By taking advantage of the laws of physics it is possible to revolutionize the way we communicate (transmit), process or even store information. It is now known that quantum computers, or computers built from quantum mechanical elements, provide new resources to solve certain problems and perform certain tasks more efficiently than today’s conventional computers. However, on the road to a compl...
متن کاملConvexity and the quantum many-body problem
We recall some properties of convex functions and, in particular, of the sum of the largest eigenvalues of a Hermitian matrix. From these properties a new estimate of an arbitrary eigenvalue of a sum of Hermitian matrices is derived, which in turn is used to compute an approximate associated spectral projector. These estimates are applied for the first time to explain generic spectral features ...
متن کاملQuantum information in many-body systems
ABSTRACT: Quantum information sheds new light on quantum systems, complementary to the traditional point of view of energy. A key notion is entanglement, which measures quantum correlations within the system. Understanding entanglement of ground states is crucial to efficiently represent such many-body states using a small number of variational parameters. This is but one example of very powerf...
