Ground states, symmetries and dynamics of quantum many-body lattice systems

Project description

Study explores phase transitions on the quantum level

Phase transitions are commonly encountered in everyday life. A typical example is how water evaporates or freezes at 100 and 0 degrees Celsius, respectively. Such transitions also occur on the mechanical level, between different phases of matter at zero temperature that are primarily driven by quantum fluctuations. Detecting those transitions is fundamental for quantum information storage, where data is stored in the ground state of a system with many-body interactions. Funded by the Marie Skłodowska-Curie Actions programme, the QUANTLATTICE project aims to study the ground-state phases of quantum lattice systems, for example the stability of spectral gaps and the existence of symmetric invariants in 2D quantum spin systems.

Objective

This project proposes a study of ground state phases of quantum lattice systems. The problem of detecting and describing quantum ground state phase transitions is a fundamental problem in the theory of quantum computing, where quantum information is stored in the ground state space of a many-body interaction. This study focuses on three avenues of research. The first is to investigate the stability of spectral gaps and the existence of symmetric invariants in 2D quantum spin systems. Such a program has already been carried out in frustration free models with local topological quantum order such as models with projected entangled pair ground states, but there remain important and open questions in more general models. The second direction is to study applications of quasi-adiabatic continuation methods to quantum lattice systems with unbounded Hamiltonians. These results would extend known results be applicable to models such as the quantum rotor and yield information about the adiabatic theorem in previously unknown cases. Lastly, the study focuses on propagation velocities and quasi-locality of many-body quantum dynamics.

Programme(s)

Multi-annual funding programmes that define the EU’s priorities for research and innovation.

Topic(s)

Calls for proposals are divided into topics. A topic defines a specific subject or area for which applicants can submit proposals. The description of a topic comprises its specific scope and the expected impact of the funded project.

Funding Scheme

Funding scheme (or “Type of Action”) inside a programme with common features. It specifies: the scope of what is funded; the reimbursement rate; specific evaluation criteria to qualify for funding; and the use of simplified forms of costs like lump sums.
