In this thesis, we study generalizations of well-known Majorana fermion models, including the SYK model and the Klebanov-Tarnopolsky tensor model. The models are compared at finite and large N, where we find that the models simplify considerably and can even become solvable.
Spin qubits housed in silicon quantum dots are rapidly emerging as a viable quantum computing platform. In recent years, there have been single- and two-qubit gate demonstrations, which showed high fidelities to the extent that implementing quantum error correction codes appears to be within reach.
This dissertation explores various generalizations of global symmetries and ’t Hooft anomalies. Chapter two is based on work with Po-Shen Hsin and Nathan Seiberg . It is dedicated to the study of one-form global symmetries in three and four dimensions. We investigate their physical implications, classify their ’t Hooft anomalies and analyze...
A promising avenue for studying the origin and evolution of the universe is to measure the Cosmic Microwave Background (CMB), the thermal radiation remaining from the Big Bang after billions of years of expansion. Today, this remnant takes the form of an extraordinarily uniform thermal blackbody of ~2.7 K in temperature.
This thesis is devoted to studies of quantum field theories with dynamical fields in the vector, matrix or tensor representations of O(N) symmetry groups. These models provide interesting classes of exactly solvable models that can be examined in detail and give insights into the properties of other, more complicated quantum field theories.
Over the last six years, the LIGO and Virgo gravitational wave detectors have revolutionized gravitational wave astronomy by discovering the first compact binary mergers. There is much to learn about how these systems form in nature, and these discoveries have allowed to start characterizing the astrophysical population of binary black holes....
Ultracold atomic gases in optical lattices are an ideal platform for studying quantum many-body physics. The long timescales and isolated nature of these systems makes them particularly suited for exploring the dynamics of nearly closed quantum systems and their relaxation towards thermal equilibrium.
Physics defined on real manifolds and equipped with locality has achieved many successes theoretically as well as in describing our universe. Nevertheless, from a mathematical point of view, it is not as privileged. This thesis explores the possibility of non-Archimedean and non-local physics by studying a range of discrete and continuous...
