Ambiguity problem of the Bootstrap Method in Quantum Mechanics
Takeshi Morita, Worapat Piensuk, Pushkar Soni
The bootstrap method for quantum mechanics is a powerful tool for computing the energy eigenvalues of a Hamiltonian. However, we point out that this method suffers from an ambiguit…
Defining the type IIB matrix model without breaking Lorentz symmetry
Yuhma Asano, Jun Nishimura, Worapat Piensuk +1
The type IIB matrix model is a promising nonperturbative formulation of superstring theory, which may elucidate the emergence of (3+1)-dimensional space-time. However, the partitio…
Geodesic compatibility: Goldfish systems
Worapat Piensuk, Sikarin Yoo-Kong
To capture a multidimensional consistency feature of integrable systems in terms of the geometry, we give a condition called \emph{geodesic compatibility} that implies the existenc…
Integrable Hamiltonian Hierarchies and Lagrangian 1-Forms
Chisanupong Puttarprom, Worapat Piensuk, Sikarin Yoo-Kong
We present further developments on the Lagrangian 1-form description for one-dimensional integrable systems in both discrete and continuous levels. A key feature of integrability i…
Quantum resonant systems, integrable and chaotic
Oleg Evnin, Worapat Piensuk
Resonant systems emerge as weakly nonlinear approximations to problems with highly resonant linearized perturbations. Examples include nonlinear Schroedinger equations in harmonic…
