Dissipation alters modes of information encoding in small quantum reservoirs near criticality
Krai Cheamsawat, Thiparat Chotibut
Quantum reservoir computing (QRC) has emerged as a promising paradigm for harnessing near-term quantum devices to tackle temporal machine learning tasks. Yet identifying the mechan…
A Surprising Similarity Between Holographic CFTs and a Free Fermion in Dimensions
Krai Cheamsawat, Sebastian Fischetti, Lucas Wallis +1
We compare the behavior of the vacuum free energy (i.e. the Casimir energy) of various -dimensional CFTs on an ultrastatic spacetime as a function of the spatial geometry. T…
A new energy bound for Einstein-Scalar theory in AlAdS and holographic bound for deformed CFT
Krai Cheamsawat
In this work, we derive an upper bound on energetic quantities, namely vacuum energy and free energy, for static solutions of Einstein-Scalar theory in four dimensional asymptotica…
A new energy upper bound for AdS black holes inspired by free field theory
Krai Cheamsawat, Gary Gibbons, Toby Wiseman
We consider the toroidally compactified planar AdS-Schwarzschild solution to 4-dimensional gravity with negative cosmological constant. This has a flat torus conformal boundary met…
Free energy dependence on spatial geometry for (2+1)-dimensional QFTs
Krai Cheamsawat, Lucas Wallis, Toby Wiseman
We consider (2+1)-QFT at finite temperature on a product of time with a static spatial geometry. The suitably defined difference of thermal vacuum free energy for the QFT on a defo…
The minimum mass of a charged spherically symmetric object in dimensions, its implications for fundamental particles, and holography
Piyabut Burikham, Krai Cheamsawat, Tiberiu Harko +1
We obtain bounds for the minimum and maximum mass/radius ratio of a stable, charged, spherically symmetric compact object in a -dimensional space-time in the framework of genera…
The minimum mass of a spherically symmetric object in -dimensions, and its implications for the mass hierarchy problem
Piyabut Burikham, Krai Cheamsawat, Tiberiu Harko +1
The existence of both a minimum mass and a minimum density in nature, in the presence of a positive cosmological constant, is one of the most intriguing results in classical genera…
