• Title: The virial theorem and the method of multipliers in spectral theory
• Authors: Lucrezia Cossetti, David Krejcirik,
• Abstract summary: We show how to use the techniques to deduce the absence of eigenvalues and other spectral properties of electromagnetic quantum Hamiltonians. We focus on our recent developments in non-self-adjoint settings, namely on Schroedinger operators with matrix-valued potentials, relativistic operators of Pauli and Dirac types, and complex Robin boundary conditions.

• Abstract: We provide a link between the virial theorem in functional analysis and the method of multipliers in theory of partial differential equations. After giving a physical insight into the techniques, we show how to use them to deduce the absence of eigenvalues and other spectral properties of electromagnetic quantum Hamiltonians. We focus on our recent developments in non-self-adjoint settings, namely on Schroedinger operators with matrix-valued potentials, relativistic operators of Pauli and Dirac types, and complex Robin boundary conditions.

• Oscillators with imaginary coupling: spectral functions in quantum mechanics and quantum field theory [0.0]
  Non-hermitian hamiltonians with $calPT$-symmetry can have both real spectra and unitary time evolution. We analyze two-point correlation functions and their associated K"allen-Lehmann representation. We conjecture that positivity violation of some spectral functions of the theory could be a generic sign of the existence of complex pairs of energy eigenvalues.

• Entanglement Hamiltonian and orthogonal polynomials [0.0]
  We study the entanglement Hamiltonian for free-fermion chains with a particular form of inhomogeneity. We show that this deformation is interpreted as a local inverse temperature and can be obtained in the continuum limit. Using this prediction, the properly rescaled eigenvalues of the commuting operator are found to provide a very good approximation of the entanglement spectrum and entropy.

  We use a generalized tanh shaped hyperbolic potential to investigate bound state solutions of the Dirac equation. Results indicate that the energy eigenvalues are strongly correlated with the potential parameters. Using this potential to model mass spectra of charmonium and bottomonium, we show that results for the calculated quark mass spectra align closely with experimentally observed values.

  This work provides an introduction and overview on some basic mathematical aspects of the single-flux Aharonov-Bohm Schr"odinger operator. The whole family of self-adjoint realizations is characterized by means of four different methods. Special attention is devoted to those self-adjoint realizations which preserve the same rotational symmetry and homogeneity under dilations of the basic differential operator.

  We reformulate the technique of third quantization in a way that explicitly connects all three methods. We first show that our formulation reveals a fundamental dissipative symmetry present in all quadratic bosonic or fermionic Lindbladians. For bosons, we then show that the Wigner function and the characteristic function can be thought of as ''wavefunctions'' of the density matrix.
