Quantum Solitons in any Dimension: Derrick's Theorem v. AQFT
A powerful tool for studying the behavior of classical field theories is Derrick's theorem: one may rule out the existence of localized inhomogeneous stable field configurations (solitons) by inspecting the Hamiltonian and making scaling arguments. F...

Edge mode dynamics of quenched topological wires
The fermionic and Majorana edge mode dynamics of various topological systems is compared, after a sudden global quench of the Hamiltonian parameters takes place. Attention is focused on the regimes where the survival probability of an edge state has...
Nonstop is the perfect Act 1 finale!!
Seriously Lin is so genius. I once thought that Battle of Yorktown was the perfect finale for Act 1. There were many months where I actually thought this was the case. The end of the song just seeme...
Classifying Order-Two Spatial Symmetries in Non-Hermitian Hamiltonians: Point-gapped AZ an…
Crystalline topological insulators and superconductors have been a prominent topic in the field of condensed matter physics. These systems obey certain crystalline (spatial) symmetries that depend on the geometry of the lattice. The presence of spati...
Existence of periodic orbits near heteroclinic connections
We consider a potential $W:R^m\rightarrow R$ with two different global minima $a_-, a_+$ and, under a symmetry assumption, we use a variational approach to show that the Hamiltonian system \begin{equation} \ddot{u}=W_u(u), \hskip 2cm (1) \end{equatio...
Rigorous screened interactions for realistic correlated electron systems
We derive a widely-applicable first principles approach for determining two-body, static effective interactions for low-energy Hamiltonians with quantitative accuracy. The algebraic construction rigorously conserves all instantaneous two-point correl...
The Loring--Schulz-Baldes Spectral Localizer Revisited
The spectral localizer, introduced by Loring in 2015 and Loring and Schulz-Baldes in 2017, is a method to compute the (infinite volume) topological invariant of a quantum Hamiltonian on $\ZZ^d$, as the signature of the (finite) localizer matrix. We p...
Conditions for Unitarity in Timeless Quantum Theory
Quantum timeless approaches solve the problem of time by recovering the usual unitary evolution of quantum theory relative to a clock in a stationary quantum Universe. For some Hamiltonians of the Universe, such as those including an interaction term...

Dressed Qubits
Inherent gate errors can arise in quantum computation when the actual system Hamiltonian or Hilbert space deviates from the desired one. Two important examples we address are spin-coupled quantum dots in the presence of spin-orbit perturbations to...
What is the Simplest Linear Ramp?
We discuss conditions under which a deterministic sequence of real numbers, interpreted as the set of eigenvalues of a Hamiltonian, can exhibit features usually associated to random matrix spectra. A key diagnostic is the spectral form factor (SFF) -...
Struggling with the concept of spinor
Hey, everyone! I have been studying tight-binding approximations, and have got to a point of writing the TB hamiltonian using second-quantized field operators is the norm. So, I can understand the m...
Variational ansatz for quasispecies in the Eigen model
We investigate the error threshold for the emergence of quasispecies in the Eigen model. By mapping to to an effective Hamiltonian ruled by the "imaginary-time" Schrödinger equation, a variational ansatz is proposed and applied to calculate various...

Rosedon Hotel offers convenient location in Hamilton, Bermuda, just 1.9 miles from Elbow Beach and 0.5 miles from a variety of restaurants offering grilled food and international dishes and the Historical Society Museum. Victoria Park is a 2 minutes’ drive from this 4-star hotel,…
Wilson Lines Near the Light Cone
We study the dynamics of Wilson lines near the light cone in QCD. Lattice simulations of the near light cone Hamiltonian in SU(2) show that the correlation mass at strong coupling vanishes at intermediate coupling, which signals a continuum transit...
(Beware) Brass Beacon Tattoo
Brass Beacon recently opened on Elm St. in OTR. The owner Jacob (Michael) Wilson was formerly, as of 2025, a tattoo artist at Glass Ink in Hamilton, OH and was let go after response due to Nazi imager...
The Loschmidt Spectral Form Factor
The Spectral Form Factor (SFF) measures the fluctuations in the density of states of a Hamiltonian. We consider a generalization of the SFF called the Loschmidt Spectral Form Factor, $\textrm{tr}[e^{iH_1T}]\textrm{tr} [e^{-iH_2T}]$, for $H_1-H_2$ sma...
