Hollow Lattice Tensor Gauge Theories with Bosonic Matter
José M. Cruz, Masafumi Udagawa, Pedro Bicudo +2
Higher rank gauge theories are generalizations of electromagnetism where, in addition to overall charge conservation, there is also conservation of higher rank multipoles such as t…
Tricriticality in 4D U(1) Lattice Gauge Theory
Rafael C. Torres, Nuno Cardoso, Pedro Bicudo +2
The 4D compact U(1) gauge theory has a well-established phase transition between a confining and a Coulomb phase. In this paper, we revisit this model using state-of-the-art Monte…
Higgs Phases and Boundary Criticality
Kristian Tyn Kai Chung, Rafael Flores-Calderón, Rafael C. Torres +3
Motivated by recent work connecting Higgs phases to symmetry protected topological (SPT) phases, we investigate the interplay of gauge redundancy and global symmetry in lattice gau…
Dissipation-induced long-range order in the one-dimensional Bose-Hubbard model
Afonso L. S. Ribeiro, Paul McClarty, Pedro Ribeiro +1
Understanding the stability of strongly correlated phases of matter when coupled to environmental degrees of freedom is crucial for identifying the conditions under which these sta…
Mean-field approach to Mid-spectrum Eigenstates of long-range interacting Quantum Systems
Bojan Žunkovič, Pedro Ribeiro
We study the equilibrium properties of the spin- XY chain with an infinite-range transverse interaction. At zero temperature, competition between the XY- and the -ordered p…
