PT-symmetric quantum mechanics
Carl M. Bender, Daniel W. Hook
It is generally assumed that a Hamiltonian for a physically acceptable quantum system (one that has a positive-definite spectrum and obeys the requirement of unitarity) must be Her…
Exploring confinement in SU(N) gauge theories with double-trace Polyakov loop deformations
Michael Ogilvie, Peter Meisinger
Recent results applying resurgence theory to finite-temperature field theories yield a detailed analytic structure determined by topological excitations. We examine finite-temperat…
The sign problem and Abelian lattice duality
Peter N. Meisinger, Michael C. Ogilvie
For a large class of Abelian lattice models with sign problems, including the case of non-zero chemical potential, duality maps models with complex actions into dual models with re…
The Sign Problem, PT Symmetry and Abelian Lattice Duality
Peter N. Meisinger, Michael C. Ogilvie
Lattice field theories with complex actions are not easily studied using conventional analytic or simulation methods. However, a large class of these models are invariant under CT,…
PT Symmetry in Classical and Quantum Statistical Mechanics
Peter N. Meisinger, Michael C. Ogilvie
PT-symmetric Hamiltonians and transfer matrices arise naturally in statistical mechanics. These classical and quantum models often require the use of complex or negative weights an…
PT Symmetry and the Sign Problem
Peter N. Meisinger, Michael C. Ogilvie, Timothy D. Wiser
Generalized PT symmetry provides crucial insight into the sign problem for two classes of models. In the case of quantum statistical models at non-zero chemical potential, the free…
