On the trivalent junction of three non-tachyonic heterotic string theories
Yuji Tachikawa
Recently, Altavista, Anastasi, Angius and Uranga discussed a method to construct junctions and bouquets of different perturbative string theories. Following this analysis, we here…
What happens to wavepackets of fermions when scattered by the Maldacena-Ludwig wall?
Yuji Tachikawa, Keita Tsuji, Masataka Watanabe
We study wavepackets of exotic excitations after two-dimensional fermions are scattered by the boundary condition constructed by Maldacena and Ludwig, which turns elementary excita…
On invariants of two-dimensional minimally supersymmetric field theories
Yuji Tachikawa, Kazuya Yonekura
We construct a new invariant of two-dimensional supersymmetric quantum field theories (SQFTs), under a couple of assumptions on the general properties of such…
On non-supersymmetric heterotic branes
Justin Kaidi, Yuji Tachikawa, Kazuya Yonekura
A uniform construction of non-supersymmetric 0-, 4-, 6- and 7-branes in heterotic string theory was announced and outlined in our letter \cite{Kaidi:2023tqo}. In this full paper, w…
Frozen
Yuji Tachikawa
We revisit the duality between ALE singularities in M-theory and 7-branes on a circle in F-theory. We see that a frozen M-theory singularity maps to a circle compactification invol…
