The functional-integral approach to Gaussian fluctuations in Eliashberg theory
Mason Protter, Rufus Boyack, Frank Marsiglio
The Eliashberg theory of superconductivity is based on a dynamical electron-phonon interaction as opposed to a static interaction present in BCS theory. The standard derivation of…
The bound-state solutions of the one-dimensional hydrogen atom
Rufus Boyack, Frank Marsiglio
The one-dimensional hydrogen atom is an intriguing quantum mechanics problem that exhibits several properties which have been continually debated. In particular, there has been var…
Thermodynamics of Eliashberg theory in the weak-coupling limit
Sepideh Mirabi, Rufus Boyack, F. Marsiglio
The weak-coupling limits of the gap and critical temperature computed within Eliashberg theory surprisingly deviate from the BCS theory predictions by a factor of . Int…
Critical properties of the valence-bond-solid transition in lattice quantum electrodynamics
Nikolai Zerf, Rufus Boyack, Peter Marquard +2
Elucidating the phase diagram of lattice gauge theories with fermionic matter in 2+1 dimensions has become a problem of considerable interest in recent years, motivated by physical…
