Objectives

LEARNING OUTCOMES:
Knowledge of response function and static and dynamical correlation functions in simple and molecular liquids. Quantum effects on the microscopic properties of fluids. Microscopic response at low, intermediate and high wave vectors. Base knowledge of the principal experimental techniques for structure factor determination

KNOWLEDGE AND UNDERSTANDING:
Studenst will be able to acquire a comprehension of the methods to describe and characterize macroscopic and microscopic properties of liquids and glasses, including the relevance of nuclear quantum effects on the thermodynamical and microscopic properties. Verification of knowledge will be carried out at the final oral exam.

APPLYING KNOWLEDGE AND UNDERSTANDING:
Students will be able to identify the main connections between macroiscopic properties of liquids and theri microscopic structure and dynamics, relating these properties with the correspondig propoerties of other condensed phases.

MAKING JUDGEMENTS:
Students will be able to evaluate expected properties of liquid systems with increasing molecular complexity, relatong these with other condensed matter aggregation states (solid, gas). They also must be able to read and understand a scientific paper in the relevant sector

COMMUNICATION SKILLS:
Students will be able to manage and monitor their activity within their course while mantaining effective communication putting forward relevant questions and request of in depht explaination of specific subjects, and they must be able to communicate their results to apecialists as well as to a broader audience.
